Combustion adjustment test of circulating fluidized bed boiler

Sep 01, 2017 · 1. Introduction. In China, the requirements for energy conservation and emission reduction are increasingly urgent,, especially for coal-fired boilers.One of the major concerns associated with coal combustion is the emission of NO x (including NO 2 and NO). In order to improve the boiler efficiency and reduce NO x emission, many methods and techniques have been applied to new boilers and

A Control Strategy of the Air Flow Rate of Coal-Fired

Reference gives an approximate view that the annular fuel air should be controlled by the boiler load. For combustion in a coal-fired boiler, the total air flow rate should be adjusted based on the fuel amount. Therefore, studies should focus on the control strategy of the air demand in a coal-fired boiler.
