Description

Technical Field

[0001] The utility model belongs to the technical field of biomass boilers, and more specifically, it particularly relates to a modular biomass boiler. Background Art

[0002] Due to the limitations of power, natural gas supply, and gas pipelines, it is impossible to convert all coal-fired boilers in our country into electric boilers or gas boilers. However, biomass boilers are more acceptable and popular among users because of their low price and low operating cost, which exactly fills this gap. Biomass energy pellet fuel is made from all waste crops such as straw, rice straw, firewood, wood chips, peanut shells, melon seed shells, beet pulp, and bark through processes such as crushing, mixing, extrusion, and drying, and finally made into pellet fuel.

[0003] Based on the prior art, it is found that when the existing biomass boilers are in use, generally, biomass fuel is directly put into the boiler interior, resulting in low combustion efficiency. After the biomass fuel burns, a large amount of soot is generated, and the soot is likely to adhere to the tube bundles, causing blockage and affecting the filtering effect of the soot. Moreover, generally, only one economizer is installed in a biomass boiler. If it needs to be repaired or replaced, it will lead to poor energy-saving efficiency of the boiler. Summary of the Utility Model

[0004] In order to solve the above technical problems, the utility model provides a modular biomass boiler to solve the problems that when the existing biomass boilers are in use, generally, biomass fuel is directly put into the boiler interior, resulting in low combustion efficiency. After the biomass fuel burns, a large amount of soot is generated, and the soot is likely to adhere to the tube bundles, causing blockage and affecting the filtering effect of the soot. Moreover, generally, only one economizer is installed in a biomass boiler. If it needs to be repaired or replaced, it will lead to poor energy-saving efficiency of the boiler.

[0018] Compared with the prior art, the utility model has the following beneficial effects:

[0019] 1. In this device, a rotating part and a conveying part are provided. Here, the rotating part is connected to the motor on the main body, and the conveying part is connected to the main body through a hydraulic telescopic rod. Thus, when in use, biomass fuel is poured into the feeding part, and the motor on the main body drives the rotating part to rotate. The rotating part is arranged in a spiral structure, so that when rotating, it drives the biomass fuel to be conveyed, and thus the biomass fuel falls onto the grate of the fixing part. The hydraulic telescopic rod on the main body expands and contracts to drive the grate on the conveying part to reciprocate. The grates on the conveying part and the fixing part are arranged crosswise, so that the biomass fuel can be pushed, making the conveyed fuel burn more evenly, and the residues after combustion can be discharged orderly, ensuring the combustion efficiency of the biomass fuel.

[0020] 2. In this device, a tube bundle and an economizer are provided. The tube bundle is installed inside three chambers within the main body, enabling the dust in the flue gas to be intercepted by the tube bundle. Some dust can directly fall through the tube bundle. The three groups of tube bundles are arranged in a staggered manner, and the spacing between the tube bundles is set relatively large, which can better prevent a large amount of slagging on the tube bundles, affecting the flue gas emission, reducing the cleaning and maintenance cycle of the tube bundles, and improving work efficiency. The economizer can ensure that any two of the other groups can continue to operate when one group is under maintenance by being slidably installed inside the card slots on the discharge part. Moreover, the installation and disassembly are more convenient, and three groups are provided, with a higher energy-saving efficiency compared to existing boilers. BRIEF DESCRIPTION OF THE DRAWINGS
