Biomass boiler

Abstract

The invention provides a biomass boiler, belongs to the technical field of boiler equipment and solves the problems that according to an existing biomass boiler, the flue is burnt incompletely and heating efficiency is low. The biomass boiler comprises a boiler body and a storage basin. The boiler body comprises an upper water storage cavity and a lower water storage cavity. A supporting disc is rotationally connected into the boiler body. A first rotary disc and a second rotary disc are rotationally connected into the boiler body, a first heat exchange tube and a second heat exchange tube are connected between the first rotary disc and the second rotary disc, the other end of the first heat exchange tube is communicated with the upper water storage cavity, and the other end of the second heat exchange tube is communicated with the lower water storage cavity. A material conveying mechanism is arranged between the storage basin and the boiler body. A first transmission mechanism is arranged between the first rotary disc and the material conveying mechanism, and a second transmission mechanism is arranged between the supporting disc and the material conveying mechanism. The supporting disc is further provided with a ventilation mechanism. The biomass boiler has the advantages that flue can be burnt completely, and heating efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of boiler equipment and relates to a biomass boiler. Background technique [0002] Boiler is a kind of energy conversion equipment. The energy input to the boiler is in the form of chemical energy in fuel, electric energy, heat energy of high-temperature flue gas, etc. After conversion by the boiler, it outputs steam, high-temperature water or organic heat carrier with certain heat energy. . The original meaning of the pot refers to the water container heated on the fire, and the furnace refers to the place where fuel is burned. The boiler includes two parts: the pot and the furnace. The hot water or steam generated in the boiler can directly provide the required heat energy for industrial production and people's life, and can also be converted into mechanical energy through a steam power device, or converted into electrical energy through a generator. Boilers that provide hot water are called hot water bo...

Problems solved by technology

This invention mainly changes the form of air supply to form three types of combustion-supporting air in the burner: the upper direct ventilation, the middle spiral wind, and the bottom lift-up wind. The bottom lift-up wind suspends biomass particles in the burner, and the middle spiral wind Make the biomass fuel more dispersed and burn more fully, and the upper direct ventilation provides secondary oxygen supply to make the combustion more thorough, but because the water is concentrated in the water storage room, the efficiency of absorbing heat is low
