Embodiment Construction

[0027] Below in conjunction with accompanying drawing, invention is described in further detail.

[0028] Such as Figure 1-3 As shown, a biomass semi-gasification combustion equipment includes a combustion chamber 04, a gasification chamber 03 communicated with the combustion chamber 04 is provided at the upper part of the combustion chamber 04, and a combustion chamber 03 communicated with the combustion chamber 04 is provided at the lower part of the combustion chamber 04. An ember chamber 05, and a burner 02 communicating with the gasification chamber 03 is provided on the gasification chamber 03. A mixer 01 is provided at the front end of the burner 02 . The main body of the entire combustion device is arranged in a horizontal or vertical arrangement. The mixer 01 includes a nozzle for feeding air and a feed pipe 14 for feeding biomass pulverized material or biomass molding pellets on the nozzle. The nozzle is designed with reference to the structure of the Lafal nozzle...

Abstract

The invention discloses a biomass semi-gasification combustion equipment. This includes combustion chambers, gasification chambers, ember chambers, and burners. A mixer is provided at the front end of the burner. The mixer consists of a spray pipe and a feed pipe. The nozzle includes a shrink tube, a throat suction tube, and a diffuser tube. The burner includes primary air pipe, secondary air pipe, impeller and spiral blade, and center pipe. The gasification chamber is a conical cavity. The combustion chamber includes a first barrel, a tertiary air box, and a nozzle. The nozzle is to deliver the tertiary air tangentially into the first cylinder. The invention is suitable for woody and herbaceous biomass fuels, and can be fully burned, and the particle size used at the same time can meet the requirements of wide sieving fuels, no coking, no ash after burning, and significantly reduce fuel drying and molding processes. The effect of manufacturing costs.

Description

technical field [0001] The invention belongs to the field of thermal energy power equipment, and in particular relates to a biomass semi-gasification combustion equipment which uses biomass pulverized material or biomass shaped granular material as fuel and applies a semi-gasification combustion process. Background technique [0002] Biomass energy has the characteristics of renewability, wide distribution, low pollution (zero emission of carbon dioxide) and huge total resources. Biomass carbon fixed by plant photosynthesis every year on the earth reaches 1.8×10 11 t, contains heat energy up to 3×10 21 J, equivalent to 10 times of the world's total annual energy consumption. Similarly, in my country, there are still various agricultural and forestry wastes equivalent to 700 million tons of standard coal that have not been utilized every year. Guangdong Province, which accounts for nearly 50% of the domestic consumption of biomass pellets, only used 500,000 tons of biomass ...
