Problems solved by technology

[0002] Most of the existing coal-fired boilers adopt the structure of increasing the heating area of ​​the boiler or increasing the flow of flue gas in the furnace in order to improve thermal efficiency and reduce pollution. However, the problems of insufficient coal combustion and low heat utilization rate cannot be completely solved. Smoke and combustible gas are discharged, seriously polluting the environment. Therefore, the core of solving ambient air pollution caused by boilers is to enable coal to fully burn in boilers

Embodiment Construction

[0010] Taking a one-ton boiler as an example, the drum is welded with a 3.0 mm thick steel plate, with a total height of 1500 mm and a diameter of 1000 mm. The automatic circulation pipe is welded with a seamless galvanized iron pipe with a diameter of 32 mm. The air guide pipe between the bottom of the furnace and the combustion chamber is welded with a seamless steel pipe with a diameter of 25 mm, and its length is 100. There are 200 air guide pipes in total. The combustion chamber is welded with a 5 mm thick iron plate, the combustion chamber is supported by the air duct, and suspended in the drum, and there is one recombustion chamber, and the outer wall of the outer honeycomb cylinder of the recombustion chamber is welded with a 2.0 mm thick iron plate, with a diameter of 150 mm, height 150 mm, the outer honeycomb cylinder is welded with thick 2.0 iron plate, diameter 130 mm, height 150 mm, holes of φ5 mm are evenly distributed on the wall of the cylinder at intervals of 2...

Abstract

In the after-combustion type boiler with low power consumption, high efficiency and no smoke, the combustion chamber has air pipe connected to atmosphere in the bottom to "suspend" it in the boiler barrel, burning port in the top communicated to a re-combustion chamber and at least one heat conducting medium box; and the re-combustion chamber has one heated device on the upper part. The present invention has simple structure and high heat efficiency, and its re-combustion chamber produces secondary combustion to make the boiler possess complete combustion, no smoke, no environmental pollutionand no need of chimney.

Description

technical field [0001] The invention belongs to a coal-fired boiler. Background technique [0002] Most of the existing coal-fired boilers adopt the structure of increasing the heating area of ​​the boiler or increasing the flow of flue gas in the furnace in order to improve thermal efficiency and reduce pollution. However, the problems of insufficient coal combustion and low heat utilization rate cannot be completely solved. The exhaust of smoke and combustible gas seriously pollutes the environment. Therefore, the core of solving the ambient air pollution caused by boilers is to enable coal to fully burn in the boiler. Contents of the invention [0003] The purpose of the present invention is to provide a recombustion type low-consumption and high-efficiency smokeless green boiler with sufficient coal combustion, high thermal efficiency and no smoke discharge, so as to solve the problems existing in the prior art. [0004] The purpose of the present invention is achieve...
