Embodiment Construction

[0036] See attached picture. The hydrogen production system disclosed in this embodiment is a coal combustion coupled with steam gasification of garbage, including a circulating fluidized bed coal combustion system, a fixed bed garbage gasification system, and a synthesis gas treatment system. Among them, the design of the coal-fired system is based on the HG-480 / 13.7L.MG31 circulating fluidized bed boiler with a power of 135MW, and the design of the gasification system is based on the experimental data of the fixed bed.

[0037] The circulating fluidized bed coal combustion system includes: a fluidized bed combustion furnace 1 , a cyclone separator 3 at the outlet of the combustion furnace, a return leg 4 , a screw feeder 14 for the combustion furnace and a waste heat boiler 16 . The lower part of the left wall of the fluidized bed combustion furnace 1 is provided with a pulverized coal feeding port, which is connected with the screw feeder 14 of the combustion furnace, and t...

Abstract

The invention discloses hydrogen production system and method by coupling coal combustion with garbage water vapor gasification. The system comprises: a circulating fluidized bed coal firing system used for burning garbage coke and pulverized coal to generate hot sand and hot flue gas and producing steam for heat supply or power generation; a fixed bed garbage gasification system used for converting the household garbage into coke and hydrogen-rich synthesis gas; a synthesis gas treatment system is used for cooling and purifying the synthesis gas, separating out tar impurities and obtaining high-quality hydrogen-rich synthesis gas. According to the system, the garbage is gasified under the reducing condition, and the gas production rate and the gas production quality are improved through steam reforming reaction of water vapor, tar and coke, so that the hydrogen-rich synthesis gas is obtained, and the garbage hydrogen production function is realized.

Description

technical field [0001] The invention belongs to the field of solid waste disposal, and in particular relates to a hydrogen production system and method for coal combustion coupled with steam gasification of garbage. Background technique [0002] In order to reduce the damage to the human environment caused by the pollutants produced in the process of energy use, people pay more and more attention to the development and utilization of hydrogen energy. As a relatively ideal secondary energy source, hydrogen energy is clean and pollution-free, has a high calorific value of combustion, and is convenient for storage and transportation. It is regarded as the energy source with the most development potential in the future. [0003] With the acceleration of urbanization, the problem of "garbage siege" has become increasingly prominent, and how to realize the recycling and harmless disposal of garbage has become an urgent problem to be solved. The organic components of municipal sol...
