Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of boilers, in particular to a recycled biomass boiler. Background Art
[0002] A boiler is a device used to generate steam or hot water. It produces steam by burning fuel (such as coal, natural gas, oil, or biomass) or by using electricity to heat water. Steam can be used in a variety of industrial processes, such as heating, power generation, food processing, textiles, and papermaking. The design and size of a boiler can vary greatly depending on its use and the amount of steam required.
[0003] A biomass boiler is a type of boiler that uses biomass energy as fuel, converting biomass materials into heat for heating, power generation, or industrial production. Biomass materials include wood, crop residues, and organic waste. These boilers are typically designed to efficiently burn biomass fuels, reducing reliance on fossil fuels and lowering greenhouse gas emissions. When designing and operating a biomass boiler, factors such as combustion efficiency, emission standards, and fuel pretreatment and storage must be considered.
[0004] The biomass boilers currently on the market have low thermal efficiency when burning biomass fuel and cannot effectively recover waste heat, resulting in energy waste. To this end, we provide a biomass boiler that recycles and utilizes waste heat. Utility Model Content

[0007] A further technical improvement of the present invention is that the ventilation pipe comprises a ventilation pipe, one end of which is connected to the inside of the heating cylinder, and the other end of which is connected to the top of the reheat box.
[0008] A further technical improvement of the present invention is that the connecting pipe comprises two connecting pipes, one end of the two connecting pipes is connected to the water flow area of the installation box, and the other end of the two connecting pipes is connected to the interior of the reflux cylinder.
[0009] A further technical improvement of the present invention is that a feed pipe is provided at one end of the heating cylinder away from the ventilation pipe, the feed pipe is communicated with the outside of the installation box, and a plurality of air intake pipes are sequentially provided on the feed pipe.
[0010] A further technical improvement of the present invention is that a water inlet pipe is provided on one side of the bottom of the installation box, and a steam pipe is installed on the top of the installation box.

[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] (1) This device adds biomass fuel to the heating cylinder through a feed pipe. The biomass fuel burns in the heating cylinder and provides the oxygen required for combustion through multiple air inlet pipes, so that the heating cylinder heats the water in the water flow area of the installation box. The flue gas generated by the combustion of the biomass fuel reaches the reheat box through the ventilation pipe. The reheat box adds heating water to it through the water inlet pipe 2. The heating water mixes with the flue gas, which increases the temperature of the heating water, thereby heating the water in the reflow cylinder, thereby improving the heating utilization efficiency of the boiler and efficiently recovering and utilizing heat energy.

The mud formed by the combustion of biomass and water is usually called biomass ash mud or biomass ash mud. It can be used for many purposes. For example, it can be used as a soil conditioner to increase the fertility and water retention capacity of the soil. It can also be used to make building materials such as bricks and cement, or as an adsorbent for water treatment and air purification. In some cases, it can also be used as a fertilizer to provide plants with essential minerals. BRIEF DESCRIPTION OF THE DRAWINGS
