Coal fired power plant applications
In coal fired power plant duty the dosing device for boiler coal fired power plant works continuous power plant auxiliary service. We size the shaft, bearings and actuator for the actual dust load and temperature of the duct, not just the nominal cross-section, because a gate that jams during a shutdown trip costs far more than the difference in purchase price. Critical welds are inspected 100% on the first unit and by sampling (AQL 1.0) afterwards.
