The Applied Research on the Small Oil Gun Ignition

2020-12-21 · As an oil-saving measure in benchmarking management activity, the technical reformation of the burner of boiler No. 2 in Hubei Xisaishan Generation Corporation Limited was introduced, in which the gasified small oil gun ignition technology and combustion stabilizing device were used. According to the pulverized coal burning theory, combining with coal quality fired in the plant practically

Computational Study of 16 kWth Furnace Cofired

This paper presents a computational study on air-fuel combustion of bituminous coal and liquified petroleum gas (LPG) in a 16 kW th test facility with a coflow-swirl burner. The performance of three turbulence models is investigated for the furnace operated under both air-staged and un-staged conditions by comparing their predictions with the reported measurements of temperature and species

The coal is ground so that about 70 will pass through 200 mesh 0.075 mm and 99 will pass through 50 mesh 0.300 mm. A pulverized coal boiler can be easily adapted for other fuels like gas if required later without much difficulty. with demonstrated operating experience at this value with the 550 MW bituminous coal-fired unit at Rostock

What Causes Clinkers in Coal Fired Boilers? | Hunker

Clinkers resemble volcanic ash and lava. They occur in the high-temperature furnace area of the boiler. Clinkers form as a result of interaction among coal quality, boiler design and boiler operation. Coal boilers draw their combustion air from the bottom, up through the combustion grate.
