### Efficiency factors in natural gas fired steam boilers

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 temperature of the a 3.5% efficiency loss occurs and the thermal reduces by 2.4 Gcal/h to 68.6 Gcal/h.

A natural gas burner rated at 40000 BTUs per hour divided by 1000 BTUs per cubic foot uses approximately 40 cubic feet of natural gas in one hour. Exact Gas Consumption Step 1 Multiply the burner efficiency by the energy content of the gas being used. Natural gas contains 1075 BTUs per cubic foot; propane contains 2570 BTUs per cubic foot. Step 2

How much gas your boiler consumes will depend on its size efficiency and how many hours its in use per day. Boiler sizes are measured in kilowatts (kW) and range from 24-27 kW 28-34 kW and 35-42 kW. A house with one bathroom and 10 radiators would need a 24-27 kW boiler whereas a large house with over 20 radiators and three bathrooms or more would need a 35-42 kW 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 600000 kcal (fixed value) the natural gas calorific value is 36.22 MJ/Nm3 (fixed value) and the thermal efficiency is 92% (non-fixed value).
