Embodiment Construction

[0014] See figure 1 and figure 2 , there is a secondary air blowing device at the front arch 6 of the furnace of the biomass boiler, and a drug delivery structure is also arranged in the secondary air spraying device. While the flue gas is disturbed, the dosing structure sprays combustion aids into the furnace. The combustion aid can be one or a combination of combustion aids, catalysts, and cracking agents

[0015] Wherein, the secondary blowing device comprises a secondary blowing pipe 3 and several nozzles 8, and several nozzles 8 are vertically installed on the secondary blowing pipe 3 along the length direction of the secondary blowing pipe air pipe 3, and several nozzles 8 pass through the furnace The front arch 6 communicates with the furnace 9;

[0016] The dosing structure includes a dosing tube 4, the dosing tube 4 is set in the secondary air spray pipe 3, and the dosing pipe 4 is provided with a number of drug delivery connectors 10, which are in one-to-one comm...

Abstract

The invention provides a secondary air blowing and chemical feeding combined structure of a biomass boiler. The secondary air blowing and chemical feeding combined structure of the biomass boiler can effectively solve the problem that by the adoption of a biomass boiler formed by transforming a traditional coal-fired boiler, biomass fuel has a negative influence on a heated surface in the combustion process and can also guarantee that biomass particle fuel is fully combusted. A secondary air blowing device is arranged at a front arch of a hearth of the biomass boiler. A chemical feeding structure is further arranged in the secondary air blowing device. The secondary air blowing device blows secondary air into the hearth so as to accelerate smoke disturbance in the hearth, and a combustion assistant is sprayed to the hearth by the chemical feeding structure at the same time.

Description

technical field [0001] The technical field of the biomass boiler structure of the present invention is specifically the combined structure of the secondary air and the drug delivery of the biomass boiler. Background technique [0002] Most of the existing biomass boilers are transformed from traditional coal-fired boilers. The biomass combustion is sent from the hopper to the front of the grate through the conveying air pipe, where it is gradually affected by the high-temperature flue gas and conveying wind at the front of the grate. Preheating, drying, burning, and at the same time, driven by the fire grate, it burns and moves to the rear until it burns, and finally the ash falls into the slag outlet behind the furnace. Due to the light weight of biomass fuel, when burning in the furnace, it is easily carried to the upper space of the furnace by the flue gas in the furnace, which will cause wear and tear on the heating surface and easily ash on the heating area; and because...
