ABSTRACT:
A system for utilizing a fuel having a high ash content, water content in excess of 50% and large particles of combustibles is shown which includes a holding tank for the fuel. Fuel is circulated in the holding tank to maintain the consistency of the fuel and a metered portion is removed, strained and fed to a combustion device. The combustion device is a fire tube boiler for generating steam and includes a furnace tube insulated with refractory material extending for its entire length. The system mixes a preselected amount of atomized fuel with combustion air and natural gas. Special ash and particulate accumulation means are provided in the boiler. The boiler also has a water spraying system in its combustion chamber to reduce combustion temperature and increases water content of the combustion mixture based on the temperature of the combustion gases at the end of the furnace tube. Finally, when the boiler is shut off, the entire system, including a bypass system, may be purged by air or water.
