Liquid methanol heating furnace

Abstract

The invention discloses a liquid methanol heating furnace which is a device integrating liquid methanol low-temperature start, methanol vaporization, methanol catalytic combustion and water preheating. The device is composed of a liquid methanol start cavity, a methanol and water preheating cavity, a methanol vaporization cavity, a methanol catalytic combustion cavity and a methanol exhaust gas secondary combustion cavity. In normal operation, liquid methanol is completely converted into carbon dioxide and water after being subjected to preheating, vaporization, catalytic combustion and secondary catalytic combustion; released heat is used for heating water, and hot water is used for civil heating or sanitary purposes. The device is compact in structure, sufficient in methanol combustion and high in thermal efficiency; no by-products such as CO are generated, hot and cold fluids are alternately distributed, local hot spots in a system can be effectively avoided, system operation is safe, the device can be widely applied to civil heating or sanitary facilities with methanol or other liquid fuel as fuel, and the device has the advantages of being clean, safe, hygienic, reliable and the like.

Description

technical field [0001] The invention belongs to the technical field of new energy, and in particular relates to a liquid methanol heating furnace. Background technique [0002] Coal-fired heating has become the most important source of pollution in Beijing-Tianjin-Hebei and surrounding areas in winter. In these areas, the consumption of civilian coal is large and widespread, and the phenomenon of coal quality exceeding the standard is common, resulting in a large amount of pollutant emissions from civilian coal combustion. Burning the same ton of coal, the air pollutants emitted by civilian stoves may be several times or even ten times that of coal-fired boilers with efficient air pollution control measures. Residential coal-fired heating emissions still have the characteristics of "rigid demand, high pollutant discharge, multiple points and scattered and difficult to control", especially for rural residents' heating in winter. Burning is difficult to manage". [0003] Ac...

AI Technical Summary

Problems solved by technology

[0006] It can be seen that alcohol-based liquid fuel stoves or alternative combustion devices mostly use preheating or complex structural systems to realize gasification, and preheating is still required to start ignition, which is inconvenient to use and wastes energy and time.
