How to calculate boiler efficiency by Direct Method

Lexington Series gas-fired, direct-vent/sealed combustion boilers combine outstanding performance and efficiency in an easy-to-install and service design. Lexington Series direct vent boilers use outside air for combustion to reduce heating costs and provide safe, dependable operation.

What is the thermal efficiency of a gas fired boiler

(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). Tuning the boiler reduces the excess air to 9.5% with a flue gas minus combustion

Improve Your Boiler's Combustion Efficiency

Boiler efficiency may be indicated by. Combustion Efficiency - indicates a burners ability to burn fuel measured by unburned fuel and excess air in the exhaust; Thermal Efficiency - indicates the heat exchangers effectiveness to transfer heat from the combustion process to the water or steam in the boiler, exclusive radiation and convection losses; Fuel to Fluid Efficiency - indicates the

Steam boiler fuel to steam efficiency Clayton Thermal

Jan 08, 2021 · Natural gas steam boiler adopts all wet back structure, large diameter corrugated furnace, effective absorption of thermal expansion, radiation heating area is large, improve the boiler operating environment, improve the boiler service life.Industrial natural gas boiler is equipped with high-quality combustion equipment, fuel combustion is sufficient, thermal efficiency is up to 95% or more

Is a high efficiency, condensing gas boiler the best

Nov 24, 2016 · Boiler Efficiency:-Thermal efficiency of boiler is defined as the percentage of heat input that is effectively utilized to generate steam. There are two methods of assessing boiler efficiency. 1) Boiler Efficiency by Direct Method: Where the energy gain of the working fluid (water and steam) is compared with the energy content of the boiler fuel.

Boilers - Natural Gas Efficiency

The boiler efficiency is usually reduced to 84-85%, when a coal fired boiler is converted to natural gas. The biggest change is due to the combustion of Hydrogen. This is normally a 4% heat loss while firing coal and about a 11% heat loss while firing natural gas. When firing natural gas, other losses such as dry gas loss, moisture in fuel and

Boiler Efficiency -

Boiler 7 has 100 ton/h capacity. High pressure steam is produced at 38 bar and 440°C which represents 79 Gcal/h of thermal power. When this boiler works at 90% efficiency, the thermal power is 71 Gcal/h. Due to the high stack gas temperature of the boiler, a 3.5% efficiency loss occurs and the thermal power reduces by 2.4 Gcal/h to 68.6 Gcal/h.


Aug 13, 2018 · Condensing boilers produce heat by burning natural gas or propane fuel. The word "condensing" refers to the fact that these appliances are able to extract heat from the combustion process so efficiently that the flue gases leaving the boiler are at a much lower temperature than in a conventional boiler.
