Problems solved by technology

However, the ignition of combustible gases such as propane and butane not only requires storage space, but also may cause explosion and other safety hazards if the molding material is on fire after leakage.
The electric pulse ignition proposed in the invention patent (application number 2014101512789) has the problem of intermittent ignition sparks when the electrode gap is too large, and the success rate of ignition when the electrode gap is small, because the formed pyrolysis gas changes the discharge characteristics of the electrodes
[0005] In addition, for molded fuels with high ash content, the combustible gas is relatively reduced during py

Abstract

The invention discloses an automatic fire-leading igniting device and an igniting method for biomass briquette. The automatic fire-leading igniting device comprises an ignition chamber, and is characterized in that a feeding device and an ignition device are arranged above the ignition chamber, a main combustion device is disposed below the ignition chamber, and a smoke discharge device is mounted on one side of the main combustion device. According to the automatic fire-leading igniting device and the igniting method for the biomass briquette, ignition of the biomass briquette is divided into ignition of leading fire and ignition of main fire, a fire-leading material is ignited and then a main material is ignited, forming materials are few during ignition of leading fire, the passing air amount is small, reliably rapid ignition can be achieved, ignition energy consumption is reduced, and smoke discharge amount and dust content are reduced.

Description

technical field [0001] The invention relates to the field of biomass briquette fuel combustion, in particular to an automatic ignition device and ignition method for biomass briquette fuel. Background technique [0002] With the acceleration of urbanization and the continuous improvement of farmers' living standards, rural energy consumption continues to expand, and the contradiction between rural energy supply and demand has become increasingly acute. Biomass with "recyclability" and "environmental protection" will become the main heating element for new rural buildings. One of energy. At present, biomass briquettes are mainly used for biomass power generation, building heating, and cooking, and the utilization method is mainly direct combustion, especially for household heating in Europe, Canada and other countries. [0003] Ignition in direct combustion is the key. Biomass ignition mostly adopts technical methods such as hot air ignition, solid or liquid fuel igniti...
