Abstract

The invention relates to a biomass combustion boiler, in particular to an underfeed type biomass combustion boiler to solve the problems that in the prior art, air distribution is not reasonable, reverse combustion is likely to happen, combustion is not sufficient, and the heat efficiency is low. A feeding cylinder is arranged in a hearth. The lower end of the feeding cylinder communicates with the interior of a spiral feeder. A primary air distribution pipe communicates with the feeding cylinder. A secondary air distribution pipe is located above the primary air distribution pipe and communicates with the hearth. A flue is arranged at the upper end of the hearth. A smoke outlet pipe is arranged at the outlet end of the flue. A chimney is arranged on the smoke outlet pipe. A settling chamber is arranged below the smoke outlet pipe and communicates with the smoke outlet pipe through a pipeline. An inflaming retarding plate is inserted in the side wall of the hearth, and one end, located outside the hearth, of the inflaming retarding plate is connected with an electric push rod. When the electric push rod is elongated, an upper port of the feeding cylinder is covered with the inflaming retarding plate, and when the electric push rod is shortened, the inflaming retarding plate disengages from the upper port of the feeding cylinder, and the chimney is provided with an induced draught fan. The biomass combustion boiler is used for combusting biomass fuel.

Description

technical field [0001] The invention relates to a biomass combustion boiler, in particular to a bottom feeding biomass combustion boiler, which belongs to the technical field of combustion equipment. Background technique [0002] The ignition process of biomass briquette refers to the process from the beginning of the reaction to the temperature rise to the intense combustion reaction after the biomass briquette fuel contacts and mixes with oxygen molecules. To realize the ignition of biomass briquette fuel, it must be satisfied that a certain concentration of volatile matter is precipitated on the surface of biomass briquette fuel, and there must be an appropriate amount of air around the volatile matter and a sufficiently high temperature. The ignition process of biomass briquettes is: [0003] (a) Under the action of the heat source, the water gradually evaporates and escapes from the surface of the biomass briquette fuel; [0004] (b) Subsequently, the organic matter i...
