The boiler adopts an environmentally friendly combustion method - full premixed combustion, and the gas and air are precisely adjusted and premixed in advance to ensure more complete combustion.
The boiler adopts a double-drum longitudinal "D" type arrangement structure; water, steam or steam-water mixture flows in the pipe; flame burns and flue gas flows outside the pipe, forming extremely fast steam-water.
· Energy Energy Energy - Feedwater Energy Flow; Step 5: Determine Fuel Energy Fuel Energy; Assumptions Deaerator provides feedwater near the boiling temperature for the deaerator's set operating pressure (Saturated Liquid) Steam Boiler and Blowdown Pressure are the same
Divide the BTU output by the approximate conversion factor A natural gas burner rated at 40000 BTUs per hour divided by 1000 BTUs per cubic foot uses approximately 40 cubic feet of natural gas in one hour Exact Gas Consumption Step 1 Multiply the burner efficiency by the energy content of
The rated evaporation capacity of the boiler is 10 tons per hour the calorific value of natural gas is 35438 MJ/Nm3 and the boiler efficiency is calculated at 95% The gas consumption of the boiler The efficiency of gas fired boilers produced by different boiler manufacturers is different

For example The calculation formula of fuel demand for steam boiler(saturated steam boilers) is as follows: of mechanical incomplete combustion loss% B=100Q/ (Qdw*) B kg/h Q- effective heat utilization of boiler kj/h Qdw- Low calorific value of fuel kj/kg - boiler thermal
tion For example we operate 1 ton gas boiler for 1 hour (full load) The boiler output is 600000 kcal (fixed value) the natural gas calorific value is 3622 MJ/Nm3 (fixed value) and the thermal efficiency is 92% (non-fixed value) According to the actual situation of the boiler the calculation is carried out
