Problems solved by technology

On the one hand, the use of the automatic feeding device improves the stability of the combustion in the furnace, and on the other hand, it cancels the nighttime fire sealing link, thereby improving the combustion efficiency and reducing the generation of pollutants and tar; however, the automatic feeding device is arranged obliquely, The frictional resistance between the straw briquette fuel in the silo and the wall of the silo is relatively large, which will inevitably increase the power consumption of the low-speed motor
In addition, the combustion chamber and the silo are connected by a material channel, and the flame in the furnace has a strong thermal radiation effect on the straw briquette fuel in the silo, which will promote the thermal decomposition of the fuel, and in extreme cases, smoke will appear

Abstract

The invention relates to a household direct-fired heating appliance using compressed straw as fuel. The household direct-fired heating appliance comprises a heating furnace and an automatic feeder, which form an H-shaped structure and which are connected through a material pass. The upper structure of the heating furnace comprises the material pass, a smoke pass, a smoke window, a water jacket, a water-cooled grate, a convection bank, a balance tube, a water-cooled partition, an anti-radiation retainer, and a waste heat recovery water jacket. The lower structure of the heating furnace comprises a rocking grate, a combustion pass, a secondary air chamber, an insulation layer and an ash hopper. A combustion chamber comprises a main chamber and a secondary chamber. The automatic feeder comprises a speed control motor, a coupling, a screw, stirring blades, a tray, rollers, a limiting switch, a control circuit box, a motor box, and a fuel box. The automatic feeder can continuously and automatically convey the compressed straw for 12 hours; the compressed straw slips into the heating furnace through the material pass; the heating furnace combusts efficiently and stably. The household direct-fired heating appliance is high in combustion efficiency, low in pollutant emission, simple to operate, low in cost and widely applicable.

Description

technical field [0001] The invention relates to a high-efficiency and clean burning biomass fuel heating furnace and its auxiliary automatic feeding device, in particular to a household direct-fired heating equipment which uses straw briquettes as fuel and has a twelve-hour continuous automatic feeding function. Background technique [0002] Smog has become one of the main factors affecting the quality of life of Chinese people. Although the main components of particulate matter in smog are PM2.5 from motor vehicle exhaust emissions, coal combustion emissions, dust and industrial emissions, according to the National Environmental Protection According to the information provided by the Key Laboratory of Pollution Prevention and Control, “PM2.5 produced by straw burning accounts for about 5% of the total PM2.5, but PM2.5 produced during concentrated straw burning may account for the total PM2.5 in the air that day. 30% or even 40% of the total.” Therefore, local governments at...
