A biomass bundling fuel combustion test bench

Abstract

The invention discloses a combustion experiment table for biomass bale fuel. The combustion experiment table comprises a combustion device, weighing system, a temperature measuring system and a smoke component measuring system, wherein the combustion device comprises a combustion chamber of a vertical cylindrical structure, a fire grate is arranged at the bottom of the combustion chamber, and a position, close to the upper side of the fire grate, in the combustion chamber is provided with an ignitor; a smoke discharge pipe is connected to the top of the combustion chamber, and a dust remover and an induced draft fan are sequentially arranged on the smoke discharge pipe along the smoke discharge direction; an air inlet pipe is connected to the bottom of the combustion chamber, and an air blower is arranged on the air inlet pipe; the weighing system comprises a weighing meter connected with fire grate through an ejector pin; the temperature measuring system comprise a combustion temperature sensor, an indoor temperature sensor and a smoker temperature sensor; the smoke component measuring system comprises a smoke analyzer. By the combustion experiment table, the combustion feature of the biomass bale fuel can be obtained through actual combustion experiments, and accordingly combustion equipment parameters can be determined.

Description

technical field [0001] The invention belongs to the technical field of biomass combustion, and in particular relates to a biomass bundling fuel combustion experiment platform. Background technique [0002] Biomass bundling combustion technology is a better way of biomass combustion and utilization. It abandons the shortage of biomass briquettes, and has a moderate bundling density of biomass (100-500kg / m3) and low power consumption (30kWh / t ), compared with biomass briquette fuel, it can save electricity by 60-90kWh per ton and save electricity cost by 40-60 ¥ / t. At the same time, it has high production efficiency, good combustion effect and easy utilization. It has become a new technology for biomass combustion and utilization. important direction of development. [0003] However, there are few equipments that directly burn biomass bundled fuel, and the combustion equipment has not yet been finalized, and further research, experiment and development are needed.

Problems solved by technology

[0003] However, there are few equipments that directly burn biomass bundled fuel, and the combustion equipment has not yet been finalized, and further research, experiment and development are needed. When designing biomass combustion equipment, the parameter selection is analogous to the corresponding parameters of coal selection. Although the method is simple, its accuracy is not enough. The main reason is that the research on the combustion characteristics of biomass bundling fuel has not been in-depth.
