Three Ways to Optimize Solid Fuel Combustion - Hurst Boiler

Continuous and Uniform Fuel Feed Is Key. A boiler system lives and dies (so to speak) by the flow of fuel into the furnace. Boilers that have the most problems are ones that do not have very good control over how uniform and consistent this flow is. This principle is even more important in applications with frequent load fluctuations.
