How to calculate the gas consumption of a gas steam boiler

How to calculate the gas consumption of a gas boiler? Gas consumption = Gas boiler power /Fuel calorific value / Gas boiler heat value utilization. For example, we operate 1 ton gas boiler for 1 hour (full load). The boiler output is 600,000 kcal (fixed value), the natural gas calorific value is 36.22 MJ/Nm3 (fixed value), and the thermal efficiency is 92% (non-fixed value).

Calculator: Flue Gas Analysis | Thermodyne Boilers

Combustion of fuel release flue gases which is a mixture of Carbon Dioxide, Carbon Monoxide, Sulfur Dioxide, H 2 O Vapor, Nitrogen or Nitro-Oxides, Oxygen and ash particles. The quantity of flue gases is also calculated using stoichiometry calculation when air reacts with the fuel. You can also refer to Thermodyne's Boiler Bible that provides you the general composition of above elements for various …

Flue Gas Temperature and Heat in the Flue Gas Flow (Btu

and the weight of flue gas per pound of coal burned will be .80 × 23.42 = 18.74 pounds. The heat lost in the flue gases per pound of coal burned will be from formula and the value 18.74 just determined. Loss = .24 × 18.74 × (500 - 60) = 1979 B. t. u. The percentage of heat lost in the flue …
