Firing Systems | ERK Energy Systems

Our first combustion system dates back to the 1950's and had a 2 megawatt water-cooled inclined grate for biomass firing. Thanks to our experience with in-house water circulation, the combustion system was integrated into the boiler's natural circulation to achieve optimal cooling of all components exposed to high temperatures.

Vibrating Grate. The vibrating action of this type of water cooled firing grate is created by the rotation of an eccentric shaft moves the whole fuel bed down towards the rear of the grate. The vibrating causes the bed material to be leveled and together with the air draft dislodges the ash particles from the live fuel.

Grate Limit as it relates to Boiler Efficiency | Advanced

A simple mathematical proof that, based on Fry's equation, boiler efficiency at the grate limit is exactly half the maximum efficiency, is as follows:. Fry's Equation: E b = k 1 – k 2 x M/G, where:. E b = Boiler Efficiency; M = Firing Rate; G = Grate Area; k 1 = predicted boiler efficiency at zero firing rate; k 2 = the slope of the graph relating boiler efficiency to firing rate.
