Electronic temperature-control constant temperature boiler for biomass fuel and coal

Abstract

The invention relates to a boiler, in particular to an electronic temperature-control constant temperature boiler for biomass fuel and coal. The constant temperature boiler comprises a boiler housing, an inner tank, a furnace hearth and a smoke outlet, and is characterized in that a furnace grate, a combustion chamber and a material feeding bin are arranged on one side in the inner tank in sequence from the bottom up; the transversal S-shaped furnace hearth formed through vertical up-down-staggered inner tank clapboard water jackets is arranged on the other side of the inner tank; a water outlet, a water return opening, a water inlet and a sewage outlet are formed at the back part of the boiler housing in sequence from the top down; a safe gas outlet is formed at the top of the boiler housing; a furnace door is arranged at the upper part of a furnace grate; and primary air matching holes traversing the inner part of the furnace hearth are formed above the furnace grate and at the lower part of the front wall of the material feeding bin. The constant temperature boiler has a unique structure, can solve the problem that only the coal can be burnt in the traditional boiler and the biomass fuel cannot be burnt in the traditional boiler, and runs at a constant temperature.

Description

technical field [0001] The invention relates to a boiler, in particular to an electronic temperature-controlled constant temperature boiler for both biomass fuel and coal. Background technique [0002] At present, the fuel commonly used in boilers is coal. Due to the lack of energy, and with the development of the economy and the improvement of people's living standards, the requirements for the environment are getting higher and higher. The pollution of coal as a fuel is still a long-term problem. solved problem. The demand for energy saving and biomass energy as fuel to replace coal as fuel is also becoming more and more urgent. At present, although there have been many improved technologies for environmental protection and energy-saving coal-fired boilers, most of the effects are not very satisfactory. For boilers that can burn both coal and biomass fuel, it is extremely rare; if the fuel is changed from coal to biomass fuel, the traditional boiler must be completely ch...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art, to provide a unique structure, which can solve the problem that the traditional boiler can only burn coal but not biomass fuel, adopts the principle of primary and secondary air matching, realizes gasification combustion, and Equipped with an electronic temperature controller, the boiler is operated at a constant temperature, and it is an electronic temperature-controlled constant temperature boiler for both biomass fuel and coal.
