boiler mass and energy balance calculation. Boiler efficiency The boiler efficiencyis a measure of the goodness of the chosen process and equipment to transfer the combustion heat to the heat in steam. For the best solid fuel boilers, the boiler efficiencyis 86 … 90% [8]. Oil and natural gas

Read More12/5/2020 · This loss is calculated by subtracting the heat used in increasing steam and heat losses from the heat supplied. Heat Balance Sheet A heat balance sheet shows the complete account of heat supplied by 1 kg of dry fuel and heat consumed. The heat supplied

Read More12/2/2021 · Heat loss in terms of fuel = Heat loss / (Fuel GCV X Boiler efficiency) = 17500 / (4500 X 0.9) =4.32 kg/hr So extra coal consumption to compensate the heat loss = 4.32 X 24 =103.7 kg/day 33-A boiler of generates 85 TPH of steam at pressure 65 kg/cm2 & temperature 490 deg C, calculate the velocity of this steam if it passes through 150 NB steam line.

Read MoreBoiler Heat & Mass Balance. The program helps to make heat- mass balance of steam boiler such as the feed-water part, steam part and blow-down part. In addition, it is possible to calculate quickly for various pull-in conditions (boundary conditions).

Read More26/8/2011 · The heat losses are less at higher loads. If we consider the additional boiler duty and the additional fuel input for this additional steam generation, the HRSG comes out a winner hands down. At 50% load, the steam generation is 50,000 lb/hr, and additional boiler
