The EGAS twostage coal gasification technology featured at the plant used an oxygenblown, entrainedflow, refractorylined gasifier with continuous slag removal. Source: DOE
Boiler slag from lignite coal was successfully used for street resurfacing work in parts of southern Texas for many years. The paving mixes consisted of a blend of 75 percent by weight of lignite boiler slag and 25 percent limestone screenings, with an asphalt content of 6 to 7 percent by weight of aggregate.
Wall Soot Blowers or Water Cannon for Furnaces during Combustion of Fossil Fuel – Coal Energy Power Plants / By Dr V T Sathyanathan / Mechanical Engineering Furnace wall cleaning is a requirement in any coal fired boiler.
In a slagging combustion system, some of ash/slag generated through the combustion of solid fuels is molten and adheres to tube surfaces or the refractory wall during operation. A submodel for predicting molten slag droplet deposition in the slagging combustion systems has been developed.
The processing of coal slag typically involves crushing and screening of coal slag, and storing and/or bagging of finished product granules. In addition to receiving coal slag from a neighboring power plant, unprocessed coal slag may be delivered from coalfired power plants .

The syngas cooler is one of the most crucial and highly loaded components in the gasification plants. Convective syngas coolers operate in a gas inlet temperature range between 1,400 °C and 400 °C and gasside pressures up to 70 bar.
Table VIII8: Compositions (in units of ppm) of coal, slag, inlet fly ash (in), and outlet fly ashes (out) from Thomas Allen Steam Plant (Klein et al., 1975), and logarithm of various ratios.
Flexibility to "Variety of Coal" Merits of IGCC (1) Combustor makes coal ash molten form and collects it on furnace wall by centrifugal force of tangential flow. (2) Molten cinder ash runs down through the slag tap into water. ⇒Preventing the slagging with low ash fusion temp without enlarged gasifier. Water surface Molten slag All Right ...

The performance of hightemperature slagging coalutilization systems depend on the collection of coal ash on the reactor surfaces and the flow of the slag out of the reactor through a slagtap hole. In order to develop an analytical model for flow of the slag on a reactor wall, existing data for slag viscosity were reviewed in light of new ...
