A wood-burning pellet stove

Abstract

The invention provides a wood particle combustion furnace comprising a charging device arranged inside a shell, a combustion device arranged at an outlet of the charging device and an operation panel arranged on the shell. The charging device comprises a charging hopper fixed on the upper portion of the inner side of the shell and a conveying belt arranged under the charging device. The combustion device comprises a combustion chamber and a combustion box arranged inside the combustion chamber. An ignition bar stretches into the combustion box from the exterior of the combustion chamber. An air supplying motor and an air suction motor are arranged on the two sides of the combustion chamber correspondingly. The wood particle combustion furnace further comprises a water circulation system connected with the shell, a safety door arranged at the front end of the shell and a control system used for controlling turn-on or turn-off a switch, operation of the conveying belt, heating of the ignition bar and operation of the air supplying motor and the air suction motor. According to the wood particle combustion furnace, automatic changing, automatic ignition, frequency conversion regulation and control, automatic dust removing and easy operation can be achieved, and meanwhile intelligent growth of the control system can be achieved.

Description

technical field [0001] The invention relates to the field of biomass furnaces, in particular to an intelligent wood-burning pellet furnace capable of automatic feeding and frequency conversion control. Background technique [0002] Biomass stove refers to the indoor heating equipment that is independent or built on the wall, uses combustibles as energy, and has a chimney inside. According to the different burning materials, it can be divided into the following four types: 1) coal-burning type; 2) wood-burning type; 3) wood-burning pellet type; 4) alcohol-burning type. [0003] The wood-burning pellet stove mainly uses the combustion of wood, straw, corn stalks, garbage and other particles to generate heat and achieve heating effects. It is suitable for families in areas without gas supply. [0004] There are many problems in the use of wood-burning pellet stoves, the most prominent ones are: [0005] 1) Due to the different sources and different storage and transportation ...

AI Technical Summary

Problems solved by technology

[0005] 1) Due to the different sources and different storage and transportation conditions of the pellet fuel used for combustion, the calorific value of different fuels is different, and the combustion efficiency affected by the fireplace air flow and oxygen content is also different, so the fireplace cannot fully adapt to the fuel and Control the environment, the combustion temperature of the fireplace fluctuates greatly, and the fuel burnout rate is low, resulting in fuel waste

[0006] 2) When the pellet fuel is burned, due to the covering of ashes on the surface of the fuel, the full contact between the fuel and the oxygen in the air is affected, and the fuel cannot be burned well, resulting in fuel waste

[0007] 3) If the original components such as ignition rods and sensors fail, they will be completely unusable or out of control, resulting in continuous heating and even fire risks

[0008] 4) Existing wood-burning pellet stoves have hot air motors and feeding motors, but no suction motors, so that oxygen-containing air cannot be replenished into the furnace in time, resulting in insufficient fuel combustion, slow combustion, and even harmful gases such as carbon monoxide.

[0009] 5) The current control system of combustion and feeding is only based on the difference between the indoor temperature and the set temperature. If the fuel lacks oxygen and is not fully combusted or the temperature in the furnace is high but the hot air is not sent out of the furnace in time, it will only lead to fuel waste and later stages. The high temperature overshoot of the air outlet is too large, and the user is extremely uncomfortable

[0010] 6) If the furnace door is not closed or opened by minors unintentionally, there is a potential risk of fire or scald
