Abstract

The invention relates to a civil heating stove feeding automatically and taking haulm briquettes as fuel, which comprises two parts, namely, a stove body and an automatic feeding device. The stove body essentially comprises a combustion chamber, a wind box, a rocking grate, a flue channel and a water jacket. The automatic feeding device essentially comprises a motor, a screw rod, a stock driving groove, a limit switch and a hopper and can realize 8 hours to 12 hours of timed and rationed automatic feeding. The civil heating stove is applicable to the clean combustion process of biomass fuels, has the advantages of high combustion efficiency, high thermal efficiency, low emission of contaminants, low generation of tar and labor conservation and the like, does not cause problems like indoor contamination resulted from condensation of the tar, and has simple structure, low cost and broad application prospect.

Description

Technical field: [0001] The invention relates to biomass fuel clean combustion equipment, in particular to a civil heating stove that automatically feeds materials and uses straw briquettes as fuel. Background technique [0002] With the increasing price of coal and fuel oil and the improvement of national environmental protection policy requirements, the utilization of biomass fuel has been paid more and more attention by the state. Biomass fuels such as straws have the characteristics of zero carbon dioxide emissions during the combustion process, and are a clean and renewable energy source. However, due to the low energy density of biomass fuels, their applications are greatly limited. [0003] After the straw is compacted mechanically, the straw briquette is obtained. The straw briquette is a rectangular block material of 30×30×70mm, and its density is 750kg / m 3 Its calorific value reaches 3500kcal / kg, which is equivalent to 70% of the calorific value of anthracite. Str...
