Read More15/4/2020 · Analyzed boiler with marked stream flows of fuel, air, ash, water, flue gas, and steam passed the boundary of control area: 1 – fuel, 2 – slag, 3 – ambient air, 4 – flue gas, 5 – feedwater, 6 – steam to reheat (from High-Pressure turbine), 7 – injection water tot FG1

Read More29/11/2015 · using the formula : boiler efficiency = m x (H2-H1) / fuel consumption x calorific value H1 is the feed water enthalpy and i am told not to use thermodynamic tables I got some help from a university lecturer and solved it. Last edited: May 1,

Read MoreIt is a well known fact that the initial cost of boiler is a small part of total costs associated with the boiler over its lifetime. In the operational life of a boiler, major costs arise out of the fuel costs. Ensuring efficient operation of boiler is critical to optimize the fuel costs.

Read MoreBoiler Capacity – 1000 kg/hr Steam Pressure – 10.5 kg/cm2(g) Steam can take this as reference and calculate fuel required for any capacity of Boiler for any fuel. Fuel Consumption = steam quantity* latent heat / Efficiency * Calorific Value.

Read More23/10/2018 · Calculation formula of fuel consumption: fuel consumption = boiler output/ fuel heat value/boiler thermal efficiency; According to the above introduction, the user can calculate the fuel consumption of the boiler according to the obtained value, so as to understand the operating cost of the boiler.

Read MoreBy taking the turbine heat consumption rate together with the boiler's net efficiency η1 and fuel efficiency η2 respectively to the common formula for calculating the coal consumption rate, the

Read More17/3/2015 · Steam, Boiler, and Blowdown Pressure are the same. Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure.

Read More11/10/2018 · 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. Of course, the above formula is applicable to boilers under an ideal working conditions.
