3. The high-temperature gas flow (self-circulating flow) in the furnace and the slag flow-down promoting nozzle were used to insulate and heat the molten ash (slag) tapping hole, in order to cause slag to flow down stably. These measures solved the problems associated with the oxygen-blown gasifier.

Pulverized coal-fired boiler - Wikipedia

A pulverized coal-fired boiler is an industrial or utility boiler that generates thermal energy by burning pulverized coal (also known as powdered coal or coal dust since it is as fine as face powder in cosmetic makeup) that is blown into the firebox.. The basic idea of a firing system using pulverised fuel is to use the whole volume of the furnace for the combustion of solid fuels.

Non Destructive Testing - Hydrostatic testing of pressure

Hot work includes everything related to welding or the post weld heat treatment (PWHT). All radiographic and ultrasonic inspections should be carried out before the pressure test is started. Conducting radiography of all the weld joints assure that your weld joints are defect free but can never provide you with the assurance of mechanical

Cyclone furnace - Wikipedia

Due to Whirling action of coal and air, a large amount of heat is generated (1500-1600°C) and that covered the surface of cyclone and ashes are transformed into molten slag. The molten slag drained from the boiler furnace through a slag tap.
