PREMAC S.A.

B. El Diseñador del horno le ha pedido a usted que usted ponga dos quemadores, dos a cadalado con líneas de centro escalonadas. (Ver dibujo) Usted elije quemadores TJ de alta velocidad porque su alta velocidad es perfecta para esta aplicación.

1. Si se basa usted en el Data Sheet del quemador TJ, que modelo escogería? (Escriba elmodelo en el dibujo) __________________________________________________________

2. Cuál es la máxima potencia de este quemador? _________________________________

3. Cuál es la mínima potencia de este quemador quemando proporcional? _____________

4. Asumiendo que la potencia total de los cuatro quemadores será equivalente a la máximapotencia requerida, cuál es la máxima potencia a la cual serán operados los quemadores?

____________________________________________________________________________

C. Rangeabilidad del Quemador

Uno de los factores mas importantes en la selección de quemadores es la selección de unsistema de control que garantice suficiente rangeabilidad al quemador. La rangeabilidaddel quemador debe igualar o superar la rangeabilidad calculada en la página 3, de locontrario, el horno tendrá problemas manteniendo las ratas de producción o en condicio-

nes de vacío, o en ambas.

Hay dos maneras de controlar las ratas de potencia de los quemadores: proporcional o con aire en exceso (airefijo) hagamos el ensayo con un sistema proporcional primero:

1. Rangeabilidad Proporcional

Los caudales de aire y de combustible se mantienen en la misma relación, por ejemplo 10:1 para el gas naturalen todo el rango de potencias.

Usando los resultados que calculó en la parte B, pasos 3 y 4, calcule la rangeabilidad del quemador proporcio-nal.

Potencia máxima del Quemador= ___________________ = ___________________ =__________________________

Potencia mínima del quemador

Compare el resultado con el resultado del horno, cuál es mas alto? ____________________________________

Si la rangeabilidad del quemador es igual o igual a la del horno, bien. De lo contrario, hay mucha potencia en

bajo fuego y el temperatura en vacío se subirá. Usted tiene que encontrar una manera de operar estos quema-dores en bajo fuego.

Mire nuevamente las especificaciones en el catálogo del quemador. En este momento vemos que tipo derangeabilidad podemos lograr con exceso de aire.

2. Rangeabilidad con Exceso de aire

La relación Aire/Combustible es correcta en alto fuego. El caudal de aire se mantiene constante, únicamente secontrola el caudal de combustible.

De la página 1 de este taller, cuál es la temperatura en vacío del horno? ________________________________

Refierase a la temperatura teórica de llama en la parte de debajo de la página 52 de la guía de ingeniería , a quéporcentaje de exceso de aire corresponde 1800°F? ____________________________________________________

PREMAC S.A.

Si un quemador se opera con este exceso de aire, la temperatura promedio de los gases de salida del quemadorson similares a la temperatura del horno. Ellos serán capaces de mantener la temperatura del horno, pero no laincrementarán. En otras palabras, la rangeabilidad del quemador igualará la rangeabilidad del horno, aunqueel flujo total de gas sea mas alto que el que requiere el horno de acuerdo a nuestros cálculos de la página 3.

Ahora observe el catálogo del quemador TJ. Este nos muestra cuanto exceso de aire tolera el equipo en variaspotencias. Puede este quemador operar con el exceso de aire requerido? __________________________________

Se logran las necesidades de rangeabilidad del horno? __________________________________________________

Para poner a operar el quemador proporcional en alto fuego y con exceso de aire en bajo fuego, sólo senecesitan cambiar los ajustes del proporcionador en bajo fuego.

Air, gas and mixture piping systems should be sized todeliver flow at a uniform pressure distribution and withoutexcessive pressure losses in transit.

Two factors cause air pressure loss and consequent pres-sure variations:

1) Friction in piping and bends, and2) Velocity pressure losses due to changes in direction.

In combustion work, piping runs are usually short (under50 ft.), but often have many bends. By assuming that allvelocity pressure is lost or dissipated at each change of direc-tion and by using a pipe size to give a very low velocity pres-sure, other losses can be disregarded. In general, a velocitypressure of 0.3 to 0.5″ w.c. satisfies this need. This is equiva-lent to air velocities of about 2200 to 2800 ft/minute. Forother gases, this velocity is inversely proportional to theirgravities; consequently, higher velocities can be toleratedwith natural gas, but propane and butane piping should besized for lower velocities than air.

The accuracy of orifice meters is also sensitive to pipevelocity, so every effort should be made to keep velocity pres-sure below 0.3″ w.c. in metering runs.

The graph below shows the relationship between velocity,velocity pressure and flow for various pipe sizes handling air,natural gas, propane, and butane. Because the specific gravi-ty of most air-gas mixtures is close to that of air, mixture pip-ing can be sized the same as air piping. The error will beinsignificant.

Example:A burner requires 10,000 cfh air at a static pressure

of 13″ w.c. The blower supplying this burner develops 15″ w.c. static pressure. Piping between the two will run 15 feet,including four 90° bends. What size piping is required?

Solution: Total pressure available for piping losses is15″ w.c. - 13 ″ w.c. = 2″ w.c.

This allows a velocity pressure loss of:2 ÷ 4 = 0.5″ w.c. for each of the four elbows.

Under the “Air” column on the left-hand side of the Pvgraph, locate 0.5″ w.c. velocity pressure. This is equivalent toabout 2800 ft/minute air velocity. Locate the intersection of the 2800 ft/minute line and the 10,000 cfh line, then dropdown to the first curve below this point, in this case, 4″ pipe.This is the pipe size that should be used.

SIMPLIFIED SELECTION OF AIR, GAS AND MIXTURE PIPING SIZE

If pipe sizing charts or tables aren’t available, you canquickly estimate the maximum air flow capacity of a pipewith these simple equations:

Maximum cfh air = (Nominal pipe size)2 x 1000

The result will correspond to a velocity pressure of about 0.5″ w.c., the maximum recommended for low pressure air systems.

Optimum cfh air = (Nominal pipe size)2 x 750

This will produce a flow rate equivalent to about 0.3″ w.c.velocity pressure.

Example: What is the maximum air flow rate for 2 1 ⁄ 2" pipe?

(21 ⁄ 2)2 = 6.256.25 x 1000 = 6,250 cfh air.

% Excess Air

Oxygen curves are plotted for 1002 Btu/cu ft Birminghamnatural gas. These curves can be used for all common fuelgases and fuel oils with no more than 0.2% error in oxygencontent.

Use the “O2 – dry sample” curve with flue gas analyzersthat use dryers or condensers to remove water from the flue

gas sample. For analyzers which add water to produce a satu-rated sample, use the “O2 – saturated sample” curve.

% CO2 curves are based on typical propane and fuel oilanlyses. If the fuel composition differs, actual CO2 curvesmay vary slightly from those shown.

THEORETICAL FLAME TIPTEMPERATURE VS. EXCESS AIR

The maximum theoretical temperature of combustion gasesat the tip of a flame decreases with increasing amounts of excess air. The curve bleow shows this relationship for natur-al gas completely burned in 60°F combustion air, but is reaon-sably accurate for most other common hydrocarbon fuels.

High PerformanceVelocity Burners

New standards for velocity,emissions and flexibility

Designed to deliver more

ThermJet Burners represent a techno-

logical leap forward in every area of

design and performance that counts.

• ThermJet has the highest operating

velocity of any burner available.

• Comparison tests with competitive

models prove ThermJet delivers the

lowest emissions.

• Integrated gas and air orifices simplify

burner piping, set-up and adjustment.

• Air and gas inlets are independently

adjustable in 90° increments to suit a

variety of piping alternatives.

• Installation, operation, and

maintenance are simplified and

less costly.

• Made to last…rugged Eclipse

Combustion dependability and

reliability are built in.

• Available in fourteen sizes with max-

mum capacities from 150,000 Btu/hr.

to 20,000,000 Btu/hr. All models are

available for use with preheated

combustion air, see Bulletin 206C.

A performance leader

Valves are available for either manual or automaticcontrol and in either full port or reduced portconstruction in 1/2” through 4”, with NPT or Rcthreads. High pressure drop valves are also availablein 1/2”, 3/4” and 1”. Wafer type valves are available in6” and 8”.

Thread Connections

The 1/2” through 4” valves are available with eitherNPT or Rc threads. The 6” and 8” valves are wafertype butterfly valves designed to be sandwiched

between flanges on connecting pipes.Shutters

NPT versions : Furnished with beveled or nonbeveledshutters.

Rc versions: Furnished with nonbeveled shutters.

Indication

All Eclipse butterfly valves feature an easy to readindicator plate and a slot on the end of the shaft toprovide visual indication of the disc position.

ControlManual butterfly valves 4” and smaller have anadjusting cover for setting disc position. A lockingscrew secures the cover at the desired setting.

Automatic control butterfly valves are furnished witha control arm that can be attached to the shaft. Thisallows integration with a variety of position controldevices.

Manual wafer butterfly valves are adjusted byrotating a control arm which can be locked to theindicating plate after positioning.

Accessories

Eclipse stocks a selection of electric operators andmounting kits which can be ordered separately. Theextended shaft length on the automatic butterflyvalves allows the addition of either a second controlarm for simultaneous automatic operation in dualvalve applications, or a cam for a high/low firemicroswitch arrangement.

The ES-Series ratio regulators are used in

applications where gas to air proportional

flow is required. The gas flow is controlled as

a function of the air pressure through a

loading line which connects into the top of

the regulator. As the system air pressure

increases, it forces the ratio regulator valve

to open causing the outlet pressure to

increase until the two pressures balance. As

the load line pressure increases, the ratio of

the outlet pressure to the load line pressure

will be slightly less than 1:1.

The ratio regulators have a bias adjustment

for varying the gas flow when setting the

burner at low fire. It can be used to increase

or decrease the gas flow resulting in gas rich

or lean combustion. The adjustment is

restricted in the gas rich direction therefore

limiting the gas flow at zero air pressure.

Ratio Regulators are control valves only and

cannot be used as gas shut-off valves.

The ratio regulators are designed to optimize

performance as ambient temperature and

inlet pressure vary. Features include:

• UL recognized and CE approved for

natural gas, propane, and butane.

• Valve seat design for consistent low fire

repeatability.

• Balanced double diaphragm design

allows regulator to operate over a wide

range of inlet pressures while minimally

affecting outlet pressure.

• Rugged die cast aluminum housing.

• Corrosion resistant internal components.

• Synthetic rubber diaphragms for

excellent low temperature performance.

• Inlet pressure tap with connector (1-1/2”, 2” &3” NPT (Rp) models only).

• High turndown option available.

Note: These graphs are for natural gas (0.60 s.g.). For propane or butane, multiply the gas flow by the factor listed below to calculate the equivalent natural gas flow, then find the pressure drop from the above graphs.

Example: Find the pressure drop created by 15,000 scfh of propane through an ES369 ratio regulator.

1. Convert propane to the equivalent natural gas flow: 15,000 x 1.58 = 23,700 scfh.

2. Plot the point where 23,700 scfh crosses the ES369 curve on the above graph.

3. Translate the intersection point back to the Pressure Drop axis.

4. The pressure drop at 23,700 scfh natural gas, equivalent to 15,000 scfh propane, is approximately 23.5” wc.

Select a combustion system ratio regulator based on the followingconsiderations:

1. Ratio regulator selection based on flow:

• Define the maximum gas flow required for the system.

• Identify the ratio regulator for that flow based on the capacities listed in Model Specification Chart on page 2.

2. Minimum inlet pressure calculation:

• Define the pressure drop through the ratio regulator based on the Flow vs. Pressure Drop curves and conversion factors listed in the Specification section.

• Calculate the pressure losses through components mounted beween the ratio regulator and the burner.

• Define the gas pressure required at the burner.

• Calculate the minimum inlet pressure to ratio regulator by taking 125% of the

sum between the ratio regulator drop, component drops and burner pressure.

• Verify that the inlet pressure is within the ratio regulator limit. If not, make the necessary changes to the ratio regulator or the upstream pressure control.
