Slagging and fouling in coal-fired boilers, CCC/147 | IEA

Excessive ash deposits on a coal-fired boiler's heat transfer surfaces will reduce its efficiency, and in extreme cases a boiler can be shut down by ash-related problems. Ash deposits are known as slagging and fouling deposits according to their location within the boiler, and have the most serious impact on boiler operation in terms of cost.

Boilers Resources for Engineers, Conferences and Careers

Boilers. are closed steel vessels for heating and vaporizing water (or other fluid) into steam, often driving turbines or generators, or heating buildings. Most boilers are welded alloy-steel structures (but not stainless steels), per many industry codes. Most are fired (fueled) with oil, coal, or natural gas.

Numerical Study on the Imbalanced Flue Gas Temperature at

This work presents the numerical study on the boiler temperature stability on a tangentially-fired 700MW coal power plant. The prime objective of the project is to identify the causes of imbalance flue gas temperature at boiler rear pass and to recommend the appropriate solutions to the problem. In order to achieve the objective, technical analysis utilizing the Computational Fluid Dynamics

Lay-up of Heating Boilers

Dry lay-up should be used when the boiler will be shut down for an extended period or when there is no urgency to restart (as with a standby boiler). This method also works in areas where the idle boiler may be exposed to subfreezing temperatures. Unlike the wet lay-up method, it requires a minimal amount of monitoring.

Influence of Inner Secondary Air Vane Angle on Combustion

Industrial experiments were also performed on a down-fired pulverized-coal 300 MWe utility boiler with swirl burners. Gas temperature, concentrations of gas components (O 2, CO, and NO x ) in the burning region, and carbon content in the fly ash were measured with inner secondary air vane angles of 42°, 47°, 53°, and 60°.
