out of the boiler to maintain a given furnace pressure. When the fuel input is terminated, this balance no longer exists. The flue gas being pulled out f the furnace by the ID fan is now being replaced only by preheated air rather than by the products of combustion in the firing zone. The average temperature of the gases resident in

and fuel pressure. Smart thermostats can estimate burner on -time by knowing how long the "heat demand" command was sent to the HVAC unit, and by measuring the corresponding increase in room temperature. The HeetMeter detects burner timing with a furnace-mounted vibration sensor. The amount of fuel burned over a period of time is

Increase Pressure and Heat in your Boiler Furnace DIY

For a burner that is 95-percent efficient, divide by 0.95. In the example: 40,000 BTU divided by 1,075 = 37.21. Adjusting for burner efficiency: 37.21 divided by 0.95 = 39.17 cubic feet of natural gas consumed in one hour. Keyword: Industry steam boiler,Gas Boiler Burner,Calculate Gas Consumption.
