PM 10 emissions from industrial coal-fired chain-grate boilers

 · Jul 13, 2017 · Industrial coal-fired boiler is an important air pollutant emission source in China. The chain-grate boiler is the most extensively used type of industrial coal-fired boiler. An electrical low-pressure impactor, and a Dekati® Low Pressure Impactor were applied to determine mass and number size distributions of PM 10 at the inlet and the outlet of the particulate emission control devices at six coalfired chain-grate boilers.

Stoker-type incinerators | Municipal solid waste treatment

Advanced combustion systems. Although combustion air must be supplied to the incinerator in order to ensure complete combustion of the waste, reducing the volume of air required makes it possible not only to increase heat recovery in the waste heat boiler and thereby boost the amount of electricity that can be generated, but also to design more compact flue gas treatment equipment.

Coal-Fired Industrial Boiler Inspection Guide

Coal and air feed to the pulverizer is controlled by one of two methods: 1) proportioning the coal feed to the load demand and adjusting the primary- air supply to the rate of coal feed, or 2) proportioning the primary air through the pulverizer to the load demand and adjusting the coal feed to the rate of air flow.

Underfeeding In underfeeding coal is fed from below

Chain grate stoker: It is similar to travelling grate stoker only difference is that a chain grate stoker consists of an endless chain which forms a support for the fuel bed. Vibrating grate stoker: The stoker shakes the fuel bed intermittently. The fuel bed is inclined so that the fuel moves towards the rear of the boiler y gravity with the progress of combustion and then falls into the ash pit.
