Embodiment Construction

[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0027] As shown in Figure 1, Figure 2, and Figure 3:

[0028]A circle of coaming 2 is welded around the top of the base 1. The front of the coaming 2 is an ash chamber 42. The front of the ash chamber 42 leads to the ash chamber door 3, and the ash removal grate is installed above the ash chamber 42. 23. Above the ash removal grate 23 is the furnace 27, and above the rear and upper part of the ash removal grate 23 is the secondary combustion chamber 34 adjacent to the furnace 27, separated by a fire baffle 36 with a sandwich structure in the middle, and the fire baffle There is a flue gas channel between the lower end of 36 and the ash removal grate 23, and the surrounding and top of the furnace 27, the fire baffle 36 and the secondary combustion chamber 34 are interconnected interlayer water jackets, which constitute the main body of the boil...

Abstract

The invention discloses a biomass gasification automatic control boiler. A furnace is arranged above an ash removal grate. A secondary combustion chamber is arranged above the back of the ash removal grate. The middle is equipped with a fireproof plate with a sandwich structure. A flue gas channel is arranged between the lower end of the fireproof plate and the ash removal grate. Sandwich water jackets, which are mutually communicated, are arranged on the periphery and the top of the furnace, the fireproof plate and the secondary combustion chamber. A primary air is supplied into the furnace from a plurality of directions of the furnace. A secondary air is supplied into the secondary combustion chamber through a secondary air channel and a ventilating hole on a spoiler. An upper settling chamber is arranged above the furnace, which is communicated with the secondary combustion chamber through a fire tube. In addition, a settling and flue conversion chamber and a lower settling chamber, which are communicated through a fire tube is arranged above the furnace. The ash removal grate is a lifting grate, which can rotate around an anterior location pin and is used to adjust the height of the opening arranged between the lower end of the fireproof plate and the ash removal grate. A microcomputer control device can automatically control the operation of the boiler according to the set requirements. Using biomass fuels and coals, the invention has the advantages of high efficiency and low emission, which accords with the requirements of environmental protection and energy saving.

Description

technical field [0001] The invention belongs to the technical field of hot water heating boilers, and in particular relates to a biomass gasification automatic control boiler. Background technique [0002] Invention patent "a coal-fired water heating furnace" (patentee: Zaozhuang Duole Heating Equipment Co., Ltd., patent number: ZL 01127545.6) discloses a coal-fired water heating furnace. Both are equipped with air inlet plates, and the secondary air is introduced from above and below the entrance of the flue gas channel at the lower rear of the furnace. The combined heat exchange device of the structure can fully absorb the heat generated by coal combustion, and the combustion and temperature of the furnace can be controlled by adjusting the temperature adjustment damper and the opening and closing of the furnace air inlet. device, this kind of water heating furnace has low emission of air pollutants and high thermal efficiency. But it also has some points worthy of impro...
