Efficient novel biomass solid molded fuel combustion apparatus

Abstract

The invention discloses an efficient novel biomass solid molded fuel combustion apparatus. The efficient novel biomass solid molded fuel combustion apparatus comprises a hearth, a hopper and a feeding preheating channel, wherein a combustion chamber is arranged inside the hearth; a heat exchange tube is arranged inside the combustion chamber; one end of the heat exchange tube is communicated with a water inlet pipe, while the other end of the heat exchange tube is connected with a heat energy output device by use of an outlet pipe; a feeding hole is formed in the bottom of the sidewall of the hearth; a charging hole is formed in the top of the hopper, while a discharge hole is formed in the bottom of the hopper; the front and rear ends of the feeding preheating channel are connected to the discharge hole of the hopper and the feeding hole of the hearth, respectively; a conveying mechanism is arranged at the bottom of the feeding preheating channel; a heat conducting pipeline is arranged between the top of the feeding preheating channel and the top of the hearth; at least one stirring roller is arranged at the feeding preheating channel; rake teeth are arranged on the stirring roller. The efficient novel biomass solid molded fuel combustion apparatus is capable of increasing the heat energy utilization rate, advantageous for sufficient combustion of the fuel and capable of preventing coking.

Description

technical field [0001] The invention relates to the field of combustion equipment, in particular to a novel high-efficiency biomass solid shaped fuel combustion device. Background technique [0002] With the increasing calls for environmental protection in the society, various combustion furnaces that burn non-renewable resources such as coal have gradually faded out of the industrial and civil fields. This kind of combustion boiler not only brings serious environmental pollution, but also consumes the earth's energy day by day, which is not conducive to sustainable development. Biomass combustion device came into being, it uses the roots and stems of various natural crops as fuel, the combustion exhaust gas is mainly carbon dioxide, and the remaining substances only include some inorganic substances that can be used for fertilization. Therefore, the biomass combustion device has obtained Vigorously promoted by all walks of life. [0003] Existing biomass combustion device...

AI Technical Summary

Problems solved by technology

[0004] However, the existing combustion devices have the problems of insufficient combustion and low heat generation efficiency. The specific reasons are as follows: when the biomass fuel is poured into the combustion furnace, its own temperature is relatively low, and it needs to be absorbed in the furnace before reaching the ignition point. This process will reduce the heat production rate of biomass fuel; and in the existing combustion device, the fuel is poured into the furnace, and the fuel is piled up into agglomerates, and the contact area with the air is low, which not only causes the burning time If the length is longer, it is also very easy to cause coking, that is, the burned material on the periphery of the agglomerated fuel wraps the unburned fuel inside, resulting in insufficient combustion, low heat production rate, and waste of fuel.
