摘要
Provided is a hydrogen gasifying reaction apparatus of coal to produce synthetic natural gas through a direct reaction between hydrogen/steam and coal without using a catalyst, and to minimize the generation of hydrogen and carbon monoxide. The hydrogen gasifying reaction apparatus of coal for production of synthetic natural gas is constituted by an entrained flow gasifier(17) where a hydrogen/steam gasifying reaction occurs, compressed gas input units(7,14), a compressed steam input unit(3), a compressed coal input unit(11), non-incinerated residue and ash collection units(22,24,26), and a gas analyzer(20). To control concentration of hydrogen and pressure of a reactor, nitrogen and helium gas(12) are directly injected to the gasifier(17) through pressure controllers(6,13). If the pressure of the gasifier(17) is higher than a certain value, a signal is sent to automatic valves(4,8,15,18,25) so as to stop the gas injection or to release the gas into outside.
