Description

Environment-friendly boiler of high-efficient burning

Technical Field

The invention relates to the technical field of boilers, in particular to an environment-friendly boiler with efficient combustion.

Background

The boiler is an energy conversion device, and the boiler outputs steam, high-temperature water or an organic heat carrier with certain heat energy to the energy input to the boiler. The boiler consists of a boiler and a furnace, wherein the upper water-containing part is the boiler, the lower heating part is the furnace, and the boiler and the furnace are designed into an integrated structure and are called as the boiler.

Boilers are classified into coal furnaces, gas furnaces, oil furnaces, electric furnaces, and the like according to fuel, but boilers using coal as fuel are most widely used in view of cost. When a boiler using coal as fuel is used, firstly, a large amount of waste gases such as sulfur dioxide, carbon monoxide and smoke dust generated after lump coal is combusted cause environmental pollution. Secondly, when the coal is used as fuel to burn the boiler, the coal can be stacked to form a coal pile when the coal is added, and the coal in the center of the coal pile can not be fully burnt because the coal is covered by other coal, and can be disposed along with other completely burnt coal slag, thereby causing the waste of energy. When coal ash is used as fuel, the coal ash is also accumulated, so that the coal ash in the center of the coal pile cannot be combusted. Meanwhile, in the existing boiler, because the boiler is arranged at the upper part and the boiler is arranged below the boiler, when the boiler burns, one part of heat generated by flame directly heats water in the boiler, and the other part of heat is radiated to the surrounding environment through the boiler body, so that the utilization rate of the heat generated by the flame is not high.

Disclosure of Invention

The invention aims to provide an environment-friendly boiler with efficient combustion, and aims to solve the problem that fuel is easy to accumulate when the existing boiler works, so that the fuel is not combusted sufficiently.

In order to solve the technical problems, the invention provides the following technical scheme: an environment-friendly boiler with efficient combustion comprises a water containing pot and a combustion furnace, wherein the water containing pot is fixedly connected to the top of the combustion furnace, and a water inlet and a steam outlet are formed in the water containing pot; the combustion furnace is characterized in that a fan is arranged outside the combustion furnace, an air outlet of the fan is communicated with a fuel pipe, one end of the fuel pipe, which is far away from the fan, penetrates through the combustion furnace and is positioned in the combustion furnace, a feed pipe is communicated with the fuel pipe and is positioned outside the combustion furnace, and a dust exhaust pipe is arranged at the top of the side wall of the combustion furnace and is communicated with the interior of the combustion furnace.

The working principle of the invention is as follows: when water in a water containing boiler needs to be heated, bran powder which is ground by wastes such as chaff, straws or rice bran and the like is selected as fuel, a fire source is placed in a combustion furnace, the fuel is poured into a feed pipe when a fan is started, an air outlet of the fan is communicated with a fuel pipe, one end of the fuel pipe, which is far away from the fan, penetrates through the combustion furnace and is positioned in the combustion furnace, and the feed pipe is communicated with the fuel pipe, so that air is blown into the combustion furnace through the fuel pipe when the fan runs. And ash generated after the bran powder is combusted is discharged from the dust discharge pipe under the driving of hot air generated by combustion of the combustion furnace due to light weight.

The invention has the beneficial effects that: 1. this scheme blows in air and dust fuel in to the combustion furnace through the fan, makes the bran powder float in the combustion furnace under the drive of air current, and then the condition of piling up each other can not appear, and the bran powder that floats in the combustion furnace begins to burn in the combustion furnace after meetting the burning things which may cause a fire disaster, and the fan constantly blows in the bran powder to the combustion furnace and carries out the replenishment of fuel. Because the bran powder floats in the combustion furnace during combustion, mutual accumulation does not occur, so that the bran powder is combusted fully, and the problem of fuel waste caused by insufficient accumulation and combustion of the bran powder is avoided. 2. The combustion of the boiler by using the bran powder as the fuel reduces the emission of harmful waste gas, avoids the environmental pollution and achieves the beneficial effects of environmental protection and high-efficiency combustion.

Further, the vertical setting of inlet pipe is on the fuel pipe, and the bottom of inlet pipe is equipped with the valve. The device is characterized in that the bran powder automatically falls into the fuel pipe through the gravity action through the vertical feeding pipe, and the excessive bran powder passing through the vertical feeding pipe possibly causes dust explosion in the combustion furnace in the combustion process of the combustion furnace, so that the amount of the bran powder entering the fuel pipe is controlled by arranging a valve at the bottom of the feeding pipe, and the dust explosion is avoided.

Furthermore, a plurality of U-shaped pipes are uniformly distributed in the wall of the combustion furnace, two ends of each U-shaped pipe penetrate through the bottom of the water containing pot and are communicated with the inside of the water containing pot, and one end of each U-shaped pipe extends to the inner top of the water containing pot. When clean water is injected into the water containing pot, the clean water is filled into the furnace wall of the combustion furnace through the lower end of the U-shaped pipe, and the clean water in the U-shaped pipe is heated by heat received by the furnace wall of the combustion furnace, so that the purpose of fully utilizing the heat generated by the combustion furnace is achieved, and energy waste is avoided.

Furthermore, a protective shell is arranged on the outer wall of the combustion furnace, and a heat insulation layer is filled between the protective shell and the combustion furnace. The purpose is to prevent the heat loss of the combustion furnace.

Further, the heat insulation layer is made of ceramic fibers. The purpose is that the heat insulation layer made of the ceramic fiber has high temperature resistance, low heat conductivity coefficient and good heat insulation effect.

Further, the inner wall bottom of burning furnace is equipped with the arc, and the interior concave surface of arc is towards the fuel pipe. The aim is to guide the bran powder blown to the furnace wall to the upper space of the combustion furnace through the arc-shaped plate.
