A Study of the Features of a Novel Vortex Arch Suited for the Combustion of Anthracite Coal

Presented is a kind of new technology incorporating a vortex arch suited for the burning of anthracite coal in a traveling grate boiler. Through modeling tests an experimental investigation was conducted of the features of the vortex arch along with an analysis of its working mechanism. As a result, identified are the key conditions to be met for achieving the optimum structural dimensions of a vortex arch. The results of study indicate that the vortex arch can effectively increase the suction and transport quantity of gas flow from a rear arch to a front one, contributing to an increase in the front arch temperature. During its practical use for the first time it has been found that the vortex arch is conducive to the timely ignition of a furnace firing flaxseed coal of category III accompanied by an intensified combustion.
