Boiler Efficiency and Combustion | Spirax Sarco

This is the calorific value of the fuel, excluding the energy in the steam discharged to the stack,and is the figure generally used to calculate boiler efficiencies. In broad terms: Accurate control of the amount of air is essential to boiler efficiency: Too much air will cool the furnace, and carry away useful heat.

BOILER EFFICIENCY GUIDE - Cleaver-Brooks

key factor is fuel usage or boiler efficiency. Boiler efficiency, in the simplest terms, represents the difference between the energy input and energy output. A typical boiler will consume many times the initial capital expense in fuel usage annually. Consequently, a difference of just a few percentage points in boiler efficiency between units can translate into substantial savings.

how to calculate the fuel consumption of the boiler-zozen boiler

How to Calculate the Fuel Consumption of the Boiler-Zozen Boiler

The calorific value of the fuel is calculated according to 35.53 MJ/Nm3, then the gas consumption of the 10 ton boiler hour = 7MW*3600s/35.53MJ/Nm3/90%=788m3/h, If the calculation is carried out for 8 hours per day, then the 10 ton gas fired boiler consumes 6304 cubic meters of natural gas per day.

boiler heat calculation for fire tube boiler

Fire Tube Boiler Capacity Calculation 2018-08-03 08:43:52. A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or (many) more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating

Fire tubeor “fire in tube” boilers; contain long steel tubes through which the hot gasses from a furnace pass and around which the water to be converted to steam cir-culates. (Refer Figure 2.2). Fire tube boilers, typically have a lower initial cost, are more fuel efficient and easier to operate, but they are limited generally to capacities of 25 tons/hr and pressures of 17.5 kg/cm2.
