A Large Horizontal Biomass Diversified Raw Material Burner

Abstract

The invention discloses a large horizontal biomass diversified raw material burning machine which comprises a plurality of stock bins, a plurality of feeders, a plurality of burning chambers, an igniter, a plurality of oxygen supply fans and a flame spraying port, wherein the feeders are connected with material discharging ports in the lower portion of the stock bin, the material discharging ends of the feeders are connected with the burning chambers, the igniter is arranged at the lower portion of the corresponding burning chamber, and the flame spraying port is formed in the corresponding burning chamber. The insides of the burning chambers are divided into upper burning parts and a plurality of lower air inlet chambers by fire grates serving as horizontal boundaries, the upper burning parts are communicated into a whole, and each air inlet chamber is connected with the corresponding oxygen supply fan. By means of the stock bins and the feeders, fuel can be conveyed uniformly and cannot be piled up in the burning chambers to form ebullition type burning. The burning chambers are arranged side by side longitudinally, occupy small transverse space and better adapt to operation conditions accordingly. The flame spraying port can be formed in a relative lower position in order to adapt to the operation condition of butt joint. The air inlet chambers are formed, and each air inlet chamber is connected with the corresponding oxygen supply fan, so that oxygen supply can be regulated separately and conveniently.

Description

technical field [0001] The invention relates to a biomass burner, in particular to a large horizontal biomass multiple raw material burner. Background technique [0002] The random stacking and burning of agricultural and forestry wastes has caused great pollution to the environment, and the ban on burning straw every year is also a problem; moreover, with the continuous deterioration of the environment and the continuous depletion of fossil energy, energy saving, consumption reduction, emission reduction, and the development of new clean Renewable energy is an inevitable trend of social development. [0003] Biomass burners use organic biomass such as biomass pellets, wood chips, wood powder, and sawdust as fuel to achieve sustainable energy utilization. Existing ordinary biomass burners are generally equipped with a set of feeding equipment and a combustion chamber, especially for large-scale biomass burners, there are often the following problems: 1. Large-scale burners ...

AI Technical Summary

Problems solved by technology

Existing ordinary biomass burners are generally equipped with a set of feeding equipment and a combustion chamber, especially for large-scale biomass burners, there are often the following problems: 1. Large-scale burners feed quickly, because there is only one feed, In a short period of time, the materials on the grate in the combustion chamber will be piled up into a conical mountain shape. At this time, the air given is not enough to penetrate the interior of the materials, and boiling combustion will be formed, and the materials accumulated in the center cannot be timely 2. The horizontal dimension of a single combustion chamber should be very large, which takes up a large horizontal space; 3. The materials of large biomass burners are easy to pile up in the fire grate in the combustion chamber. The material at a high place is easy to blow out from the crater, so the crater is usually located at a higher position. In practical applications, many docking conditions of the burner are relatively low, resulting in difficulties in the docking, and even need to dig. The height of the ground is lowered to meet the docking, which causes inconvenience in use

4. With the large-scale use of biomass burners, the amount of biomass particles is increasing. It is found that many raw material manufacturers purchase waste wood, building templates, tree roots, etc., because the existing conveyors cannot transport materials with complex structures. Therefore, the purchased waste must be crushed into powder and then compressed into granules, which increases the cost a lot and wastes manpower, material and financial resources
