In order to convert an existing air-fired boiler to oxy-coal firing flue gas recirculation (FGR) is required, as discussed in other chapters. In fact all of the proposed oxy-coal boiler conversion projects are based on FGR to control the flame temperature and to maintain proper balancing of heat transfer to different parts of the steam cycle.

Adiabatic Flame Temperature - an overview | ScienceDirect Topics

Shell boilers, also known as flue boilers, have a long water tank configuration with fire tubes. The heat from the furnace or combustion chamber passes through these fire tubes to heat the water. The earliest form of this type of boiler was the Cornish boiler, which consisted of a long cylinder with a single large flue or pipe that contained the heat or fire.

Boiler Efficiency and Combustion | Spirax Sarco

Combustion efficiency, defined as the ratio of heat released by the fuel to the heat input by the fuel, is generally high in FBC systems. The combustion efficiency is typically higher than stoker-fired systems and is comparable to pulverized coal-fired systems. It is generally higher in a CFB boiler than in a BFB boiler because of the use of

Improve Your Boiler's Combustion Efficiency - Energy

On well-designed natural gas-fired systems, an excess air level of 10% is attainable. An often-stated rule of thumb is that boiler efficiency can be increased by 1% for each 15% reduction in excess air or 40 F reduction in stack gas temperature. Boilers often

1. ENERGY PERFORMANCE ASSESSMENT OF BOILERS

Using coal and other mineral solid fuels for home heating will usually result in higher emissions of both local air pollutants (such as particles and sulphur dioxide) and carbon dioxide (the greenhouse gas) than an equivalent natural gas fired system, and therefore coal fired heating will normally have a higher environmental impact than gas.
