Embodiment Construction

[0028] The present invention will be further described in detail below in conjunction with the accompanying drawings, which are explanations rather than limitations of the present invention.

[0029] refer to Figure 1-3 , a system for reducing carbon emissions by blending ammonia gas, comprising an ammonia source, a gasification device 2, a hydrogen preparation device and a furnace.

[0030] The ammonia source is connected to the input end of the gasification device 2, and the output end of the gasification device 2 is divided into three outputs, the first output is connected to the input end of the hydrogen preparation device, the second output is the output of the hydrogen preparation device One end is connected with the ammonia-hydrogen mixed burner 7 on the furnace, and the third output is connected with the ammonia nozzle on the furnace.

[0031] The ammonia-hydrogen mixed burner 7 is installed above the burnt-out air in the furnace, and the ammonia gas nozzle 8 is loca...

Abstract

The invention discloses a system for reducing carbon emission by blending combustion of ammonia gas and a control method. The system comprises an ammonia gas source, a gasification device, a hydrogen preparation device and a hearth; an ammonia gas nozzle and an ammonia-hydrogen mixed burner are arranged above the over fire air of the hearth; and the ammonia gas source is connected with the input end of the gasification device, the output end of the gasification device is divided into three paths of output, the first path of output is connected with the input end of the hydrogen preparation device, the second path of output is connected with the output end of the hydrogen preparation device and the ammonia-hydrogen mixed burner, and the third path of output is connected with the ammonia gas nozzle on the hearth. The combustion characteristic of ammonia gas is improved by doping hydrogen, the hydrogen is doped in a direct current mode, the investment cost is reduced, the application risk is reduced, emission of CO2 is reduced by doping ammonia gas into an active-service coal-fired unit to replace fire coal with the same heat value and replacing carbon-containing fuel with non-carbon fuel; and meanwhile, active-service thermal power unit resources are fully utilized, so that the survival status of a thermal power generating unit is improved.

Description

technical field [0001] The invention relates to the field of energy and environmental protection, in particular to a system and a control method for reducing carbon emissions by mixing ammonia gas. Background technique [0002] In recent years, the world's energy consumption has been increasing, and the consumption of fossil fuels will bring a series of environmental problems while bringing social and economic benefits. Therefore, it is very urgent to develop new fuels and their combustion technologies to replace fossil fuels. The development and utilization of high-efficiency and low-pollution combustion technology can effectively solve environmental problems such as the shortage of fossil energy and the greenhouse effect, and is of great significance to the sustainable development of society. Scholars at home and abroad have proposed many alternative fuels, such as ethanol, dimethyl ether (DME), biodiesel and hydrogen. Among them, hydrogen is generally favored by people ...
