Boiler 7 has 100 ton/h capacity. High pressure steam is produced at 38 bar and 440°C which represents 79 Gcal/h of thermal power. When this boiler works at 90% efficiency, the thermal power is 71 Gcal/h. Due to the high stack gas temperature of the boiler, a 3.5% efficiency loss occurs and the thermal power reduces by 2.4 Gcal/h to 68.6 Gcal/h.

27/10/2020 · Take the 3-ton gas-fired boiler as an example, the power is 1.4MW, the calorimetric value of fuel is 35.53MJ/Nm3, and the thermal efficiency of ZOZEN gas-fired boiler is between 98%. Then, the gas consumption of the 3-ton gas-fired boiler is: 2.1MW*3600s/35.53MJ/Nm3/88%=242m3/h.
11/10/2018 · 3. Determine the thermal efficiency of the boiler. Fuel consumption gas gas consumption formula=boiler output/fuel heat value/boiler thermal efficiency. So, can calculate the gas consumption of 10 tons of gas steam boiler = 6 million kcal ÷ 0.98 ÷ 8400kcal / m3 = 716m3. boiler consumpt gas fuel.
16/09/2020 · Electricity cost: The hourly power consumption of a 1 ton natural gas steam boiler is 3.5kw. Based on the calculation of 1 yuan per kilowatt-hour of industrial electricity, it needs to consume 3.5*1*8=28 yuan for eight hours a day. Water cost: 1 ton of natural gas steam boiler produces 1 ton of steam per hour, which requires 1.1 tons of water.
fraction and enthalpy of the exhaust steam. CONDENSER PROCESS (3) to (4) HEAT OUTPUT The third process is the condenser where the wet steam at point 3 is ideally turned into saturated water at the lower pressure (point 4). Condensers usually work at very low pressures (vacuums) in order to make the turbine give maximum power. The heat
A common definition of one boiler horsepower is the amount of energy required to produce 34.5 pounds (15.65 kg) of steam per hour at pressure and temperature 0 psig (0 bar) and 212oF (100oC) - with feed water at pressure 0 psig and temperature 212oF. One boiler horsepower is about 33479 Btu per hour (about 9812 watts, 8437 kcal/hr).
