The calorific value of different types of fuels will also vary. The calorific value of natural gas combustion is 8600 kcal/m3, and the calorific value of diesel is 10240 kcal/kg. However, the cost of fuel should also be considered. comprehensive. 3. Boiler thermal efficiency The thermal efficiency of the boiler is also closely related to the heating area.

Oct 22, 2019 · New technologies are constantly improving the fuel efficiency of gas boilers. In general, gas boilers more than 15 years old are far less energy efficient than newer boilers. Older boilers are also more likely to fail during a cold snap. 3. Excess Air. Extra air in the combustion chamber of a boiler absorbs energy from the gas, causing the boiler flue gases to rise in temperature.

A boiler operates for 8,000 hours per year and annually consumes 500,000 million Btu (MMBtu) of natural gas while producing 45,000 lb/hour of 150-psig steam. Stack gas measurements indicate an excess air level of 44.9% with a flue gas minus combustion air temperature of 400°F. From the table, the boiler combustion efficiency is 78.2% (E1).
