FIELD: power industry.
SUBSTANCE: effect is achieved by changing the location of refractory bricks in the wall between waterwall and waterwall-circulation sections of the boiler. At that, strong flow turbulence of combustion products appears, which decreases its speed, and therefore it increases the action tine of combustion products on heating surface. In order to achieve the effect, the device for enlarging the action time of combustion products on heating surface of boiler plant is proposed, which includes partial demolishing of front and rear walls of the boiler, removal of refractory brick of the wall, which serves for uniform and complete action of combustion products on the boiler sections. Then, the wall is restored again, but one row of bricks is laid in common way, and the next row is laid with their edges.
EFFECT: reducing fuel consumption.
