boiler vs furnace in thermal power plant

Plant Engineering | Understanding boiler bypass lines

Consider an old gravity installation. It has a high-volume system and a low-volume boiler. If the returning water is cool (less than 140 F for a cast-iron boiler), flue gases condense inside the boiler and cause corrosion. The possibility of thermal shock also exists, although this condition is usually less of concern than condensation.

Air preheater - Wikipedia

Types. There are two types of air preheaters for use in steam generators in thermal power stations: One is a tubular type built into the boiler flue gas ducting, and the other is a regenerative air preheater. These may be arranged so the gas flows horizontally or vertically across the axis of rotation.


In this boiler, even after stopping the fuel supply, coal on the bed continues to remain present in the furnace unless boiler is cooled and those materials are taken out. ü The only parameter that would indicate whether combustion is being established in a CFBC boiler is the reducing oxygen / increasing CO2 % in flue gas at furnace outlet.
