how to crush coal for gasification:

Coal Gasification

Coal Gasification: Water Gas Reaction There are several steps in coal gasification. Let's focus on step 1: conversion of the solid coal to a burnable gas. In the gasifier, crushed coal is combined with steam at high pressure and temperature. The quantity of oxygen is limited to prevent complete combustion of the coal.

Gasification - an overview ScienceDirect Topics

Gasification. Gasification is also a thermochemical process in which the reactions between fuel and the gasification agent take place and syngas (also known as producer gas, product gas, synthetic gas, or synthesis gas) is produced. The syngas is mainly composed of CO, H2, N 2, CO 2, and some hydrocarbons (CH 4, C 2 H 4, C 2 H 6, etc.).
