[0047] Example: Application of Greenhouse Biomass Fuel Burner

[0048] The biomass fuel burner designed and manufactured by the present invention has a power of 350KW and an internal combustion chamber diameter of 50cm. The invention is applied to a facility greenhouse in Daxing, Beijing, which covers an area of ​​3000 square meters. The biomass fuel burner of this invention is installed in a 350KW biomass boiler, and is equipped with a silo, a feeding mechanism, etc., to realize automatic feeding, automatic ignition, automatic control, etc., and provide heating and hot water for the greenhouse ,Such as Figure 13 shown.

[0049] The biomass fuel burner of the present invention is installed in the biomass boiler. When working, the biomass solid shaped fuel entering the feeding cylinder 3 is propelled into the inner combustion chamber 8 through the feeding screw 2, and the slag cleaning motor 6 passes through the crank 11 provides power for the slag removal device 10, the pri...

Abstract

The invention discloses a burner for a biomass fuel and belongs to the technical field of renewable energy sources. According to the technical scheme, the burner comprises a feeding motor (1), a slag-removing motor (6) and an inner combustion chamber (8), wherein the feeding motor (1) is used for conveying a biomass solid formed fuel to the inner combustion chamber (8) through a feeding screw (2); a slag-removing device (10) which is connected with the slag-removing motor (6) through a crank (11) is mounted in the inner combustion chamber (8); first inlet air during the igniting, air-heating and burning processes is supplied by a first fan (5); and secondary inlet air is supplied by a secondary fan (4). According to the burner for the biomass fuel provided by the invention, a slag-bonding phenomenon during the burning process of different biomass fuels, such as biomass formed fuel, shredded straws, and sawdust, is effectively avoided by using the slag-removing device (10), the operations of conveying the formed fuel, breaking the slag, deashing, and the like, are realized, the burning efficiency is increased, and the burner for the biomass fuel is suitable for the combustion equipment, such as biomass boilers and hot blast stoves,.

Description

technical field [0001] The invention belongs to the technical field of renewable energy, and is a biomass fuel burner, specifically applied to biomass boilers, hot blast stoves, etc. A burner on the combustion equipment to realize automatic feeding, automatic combustion, automatic slag breaking, and automatic ash cleaning. Background technique [0002] my country is the world's second largest energy producer and consumer. In 2009, my country's primary energy production reached 2.8 billion tons of standard coal, and its total energy consumption was 3.1 billion tons of standard coal. my country is also a country that is very short of fossil energy. Per capita coal resources are about 90t, only 55.4% of the world average; per capita recoverable oil reserves are 2.6t, only 11.1% of the world average; per capita exploitable natural gas is 1074m3, only 4.3% of the world average. The production and consumption of fossil energy has caused serious environmental pollution and ecolog...
