What is the difference between gas boilers and coal-fired ...

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.

Boiler Efficiency - an overview | ScienceDirect Topics

The flue gas loss depends on the final flue gas temperature and the amount of flue gases. Thus the higher the air ratio the higher the flue gas losses. The flue gases should leave the boiler at a temperature as low as possible to minimize the flue gas losses. Usually either economics equipment or corrosion issues limit the flue gas to 150 ...

Flue gas path of fire tube boiler - ZG steam boiler

Apr 11 2017 · A fire-tube boiler is a type of boiler in which hot gases from a fire pass through one or (many) more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction heating the water and ultimately creating steam. The fire-tube boiler developed as the third of the four major historical types of boilers: low-pressure ...

Coal-Fired Boiler - an overview | ScienceDirect Topics

A gas consisting mainly of CO 2 and water vapour is generated with a concentration of CO 2 between 70% and 90% depending on recycle mode (wet or dry). The recycled flue gas is used to control flame temperature and make up the volume of the missing N 2 to ensure that there is enough gas to carry the heat through the boiler.
