Improving Efficiency of Boiler in Case of Coal Hydrotransport

Abstract

There are different schemes of utilization of heat of combustion products discharged from the boilers of CHP. The efficiency of heat recovery depends on the type of combustible organic fuel. This problem is the most relevant when using solid fuel dust and coal-water slurries. Gas recirculation boilers may be used. For the secondary use of incomplete combustion products, you can use boilers designed to burn industrial gases and coal-water fuel. A variant of an experimental system for physical modeling of coal-water fuel movement through a pipeline has been proposed. The plant improves the reliability of the existing systems of inspection and monitoring of the flame burning in the furnace of the boiler unit by simulating real processes and determining the air excess factor. The use of non-standard ways to improve the efficiency of thermal schemes of CHP and boiler rooms is possible with the use of alternative types of fuel, which include the considered coal-water slurries and coal-water fuel.
