Conversion of Existing Coal-Fired Boilers to Natural Gas

2016-10-14 · Estimated Boiler Performance and Expected Plant Performance. Converting a boiler to natural gas typically decreases boiler efficiency because of the large quantity of hydrogen in natural gas. During combustion, the hydrogen is converted to water. Evaporating this water uses a portion of the flue gas energy, thus, lowering boiler efficiency.

Boiler pressure is a measurement of the pressure of the hot water passing through the central heating system. Should the boiler pressure drop too low then the central heating will fail to work. Your boiler will feature a pressure gauge that can be used to read the boiler pressure. If the needle is anywhere below 1 then the pressure is too low.
