Water cover skirt cage type rapid heat storage heat preservation heating boiler

Abstract

The invention relates to a straw-burning water cover skirt cage-shaped rapid heat storage and heat preservation heating boiler. The boiler is placed in the kang stove to recover waste heat and store heat preservation for standby. The boiler is like a "cover" and "skirt" in the middle of the stove The "cage" of the boiler allows the straw to be fully and efficiently burned. The "water cover-skirt" structure of the boiler can cover and absorb the convective rising hot air flow when the straw burns, and the "cage" structure of the boiler fully covers the flame and absorbs the flame efficiently. The radiated heat can absorb the last sliver of heat from the charcoal fire, and quickly and continuously store hot water to the hot water storage tank with a volume of more than 185 liters through the boiler water pipe and return pipe with a diameter of more than 75 mm, and keep it warm for standby, once a day The normal heating of the kang can ensure that the boiler can provide good heat to the room and the kang for 24 hours. The boiler has a rapid discharge of water vapor and an anti-overflow device, and can also overcome the adverse effects of thermal expansion and contraction on the boiler. It is widely applicable, efficient and safe Low cost, saving time and effort, low pollution and many other advantages.

Description

Technical field: [0001] The invention relates to a straw-burning water cover skirt cage-shaped rapid heat storage and heat preservation heating supply boiler. The boiler is placed in a kang stove to recover waste heat for storage and heat preservation for standby, and the stove can also be designed separately for use. Background technique: [0002] After extensive social investigation and research, it has been found that most of the heating equipment actually used by families in winter in the vast rural and pastoral areas of China in recent years is to install a kang grate on the top of the heated kang stove and connect the heating system externally to provide heat. Some kang grate boilers are A plurality of water pipes are connected in parallel in plane, and some kang grate boilers are bent into a "manger" shape, and the latest practical kang grate boiler is a flat double-layer, placed above the flame; in addition, through detailed search, it is found that: The technology c...

Problems solved by technology

[0003] The existing straw boilers are unable to fully burn straw fuel and release heat, cannot fully absorb the heat released after straw combustion, and the absorbed limited heat cannot be quickly stored for heat preservation and backup, resulting in the main problem that the boiler cannot provide stable heat for a long time , in addition, the existing straw boilers still have the disadvantages of slow burning speed, high emission pollution, easy generation of water vapor and boiling water injection, and overheating of the kang surface by burning more fuel. In order to overcome all the above-mentioned shortcomings existing in the existing straw boilers, the present invention Provide a straw-burning water cover skirt cage-shaped rapid heat storage heat preservation heating boiler, the boiler can fully and efficiently burn the straw, release heat to the maximum, can efficiently absorb the heat released after the straw is burned, and make the absorbed heat The heat is quickly stored and kept for standby, so that the boiler of the invention can provide stable heat to the room for a long time, and solve the main problem that the straw boiler cannot supply heat stably for a long time; Heat loss, reducing pollutant emissions, can automatically and quickly discharge a large amount of boiler steam, and it is not easy to cause any water vapor burns and overflow accidents. After burning more straw fuel, the surface of the kang will not be overheated, and it can also realize heat preservation and heating for the surface of the kang; other On the one hand, the boiler also has the advantages of not causing damage to the boiler due to thermal expansion and contraction, and will not be damaged due to dry burning.
