1. First of all, the largest proportion is the cost of boiler fuel, that is, gas boiler consumption * gas unit price, accounting for about 90% of the total cost. Acoording to unit tonnage boiler gas consumption and natural gas unit price, it can be calculated; 2. The cost of power consumption, running time, electricity costs.If it is steam boiler, should add feed water pump power consumption, then calculate electricity costs; 3. Steam boiler water consumption (water charges); 4. Labor cost
How to Calculate Gas Consumption in a Gas Boiler Burner?
Base model - Values represent a 1,000,000 Btu/hour gas-fired, hot-water boiler operated for 1,500 full-load hours per year with a thermal efficiency of 80%. The performance of this standard unit is based on ASHRAE 90.1-2007. Thermal efficiency (E t) - Represents a boiler's energy output divided by energy input as defined by ANSI Z21.13. A boiler's thermal efficiency rating should be used to
The AFUE Savings Calculator is designed to help you compare the heating costs of furnaces, boilers and heat pumps with different efficiency ratings (expressed in AFUE or HSPF) and fuel types. The calculator estimates your heating cost savings over a one, five, ten and fifteen year period.

Different Types of Boilers | Steam & Hot Water Boiler | How Electric
Power of 10 tons gas boiler is 7MW, the fuel calorific value calculated according to 35.53MJ / Nm3, boiler thermal efficiency 90%. Therefore, 1 hour consumption of 10 tons natural gas boiler = 7MW * 3600s / 35.53MJ / Nm3 / 90% = 788m3 / h. Fuel costs: …
