The invention discloses novel equipment for producing hydrogen by using coal gas. The novel equipment comprises a box body A fixedly arranged on the ground; the box body A is internally provided witha reaction chamber; a pipeline A outwards extending out of an external space is arranged in the left end wall of the reaction chamber in a communication way; the upper end surface of the pipeline A isprovided with a valve A in a communication way; the upper end surface of the valve A is provided with a pipeline B in a communication way; an electric heating wire is fixedly arranged in the left endwall of the reaction chamber; a filter screen is fixedly arranged between the left and right end walls of the reaction chamber; and a diffusion box is fixedly arranged in the filter screen and is fixed together with the lower end wall of the reaction chamber. The equipment disclosed by the invention is simple in structure and convenient to use; according to the equipment, coal gas combusts to generate high-temperature steam, so that the aim of producing hydrogen from the coal gas and the high-temperature steam is achieved; and the reaction speed is regulated by adopting a structure capable ofcontrolling the reaction speed, and excess steam is recovered by using liquid water and a heat transfer medium in a reaction process, so that the reliability of the equipment is improved.
