Get a QuoteThe combustion air fed into air preheater, is taken from upper part of the boiler room. The temperature of the combustion air before the air preheater is therefore between 25 and 40°C (in Finnish conditions). The flue gases 9 fexiting the boiler are usually kept above 130-150 °C in order to prevent corrosion.

Get a QuoteWell, we choose a boiler that's able to meet the heat loss of the building on the coldest day of the year, based on the heat loss load calculation we just finished. Sounds easy, but if you're not sure of the terms or the number of manufacturer terms that mean the same thing, you're heading for a world of hurt.

Then, the gas volume required for the operating hours of a 1 ton natural gas boiler = 0.7 MW * 3600 s / 36.22 MJ / Nm3 / 92% = 75 m3 / h. Note: The actual power of the boiler is generally not equal to the rated power, so the consumption of gas is only a rough estimate.
