Integrated coal gasification combined cycle (IGCC) plants are an example of the hydrogen route. Coal is gasified to form synthesis gas ( syngas) of CO and H 2. The gas then undergoes the water-gas shift, where the CO is reacted with steam to form CO 2 and H 2. The CO 2 is then removed, with the hydrogen being sent to a gas turbine combined cycle.
1 Calculation of ball mill capacity. The production capacity of the ball mill is determined by the amount of material required to be ground, and it must have a certain margin when designing and selecting. There are many factors affecting the production capacity of the ball mill, in addition to the nature of the material (grain size, hardness, density, temperature and humidity), the degree of ...
The most common heat transfer method for coal-fired boilers is the watertube method in which the hot combustion gases contact the outside of the heat transfer tubes, while the boiler water and steam are contained within the tubes. Coal-fired watertube boilers include pulverized coal, cyclone, stoker, fluidized bed, and handfed units.
