The available heat for the boiler at 500°F and theoretical combustion equals 9, 150,000 BTU per hour. If 20 percent excess combustion air was used, the available heat at 500°F would be decreased to about 79 percent of the gross heating value for natural gas (calculated from Figure 4).
Read MoreSteam at the rate of 70,000 kg/hr from the boiler drum enters the superheater inlet header at 8.3 Mpa and 485oC. Combustion products at 980oC enters the superheater proper at the rate of 160,000kg/hr. Superheater elements are made of 60 mm O.D. by 8 mm thick tubing of 30 m length.
Read MoreDec 01, 2016 · The biogas fuel supply to the boiler was adjusted according to digester-heating needs by regulating gas pressure at the burner with a throttling valve. The pressure was manually adjusted between 0.8 and 5 in (20 and 125 mm) water gage, which corresponded to 35 to 95 ft 3 /hr (1 to 2.7 m 3 /hr) of biogas, depending on outside temperatures and

Read MoreClearly if a boiler is operating over a wide temperature/pressure range, such as when boilers are on night set-back, or even a boiler with a wide burner control band, then compensation is required, since conductivity is the controlling factor. The benefits of automatic TDS control. The labour-saving advantages of automation.
Read MoreA high pressure watertube boiler (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which boils water in the steam-generating tubes.In smaller boilers, additional generating tubes are separate in the furnace, while larger utility boilers rely on the water-filled tubes

In systems of this type (an example is shown in Figure 6.5.6), where a two-port feedwater control valve varies the flowrate of water, the pressure drop across the control valve will vary with flow. This variation is caused by: The pump
