What is the difference between gas boilers and coal-fired

Jun 28, 2019 · After the coal is burned, heat is released, and sulfurized oxygen gas is generated, which is discharged into the atmosphere by the flue gas. These gases are very polluting the environment and cause harm to humans. The natural gas used in gas boilers is mainly composed of methane gas and contains a small amount of non-hydrocarbon gas.

Challenges when Converting Coal-Fired Boilers to Natural Gas

– Flue gas from the outlet of the boiler is mixed with the combustion air to the burners. – FGR reduces the combustion temperature and lowers the localized O2 concentration in the primary combustion zone to achieve a reduction in NOx. – Increasing the flue gas flow through the convective pass of the boiler increases heat transfer.

Coal-Fired Boiler - an overview | ScienceDirect Topics

Gas-side Problems. On coal-fired boilers, several kinds of deposit may be formed: slag type, alkali-matrix type (bonded), and the phosphate type, only obtained from coals with a high phosphate content (see Chapter 20). Alkali compounds and phosphates are volatilized and condensed on cooler metal surfaces; the alkalis react with sulphur dioxide and sulphur trioxide forming sulphates which bond to the metal …
