Abstract
The utility model discloses an efficient reverse-burning boiler, which comprises a boiler shell, a boiler inner container disposed inside the boiler shell, a cavity between the boiler shell and the boiler inner container, an upper hearth located above a lower hearth and an upper fire grate tube located inside the upper hearth. The upper hearth is provided with a water jacket cover cap which is communicated with the cavity between the boiler shell and the boiler inner container. An axial section of the water jacket cover cap is in the shape of a reverse U, and both ends of the reverse U shape are communicated with the cavity. The water jacket cover cap is arranged above the upper hearth, the cavity of the water jacket cover cap is filled with water for heat exchange, and therefore almost all of the heat produced by the upper hearth is absorbed by the water inside the cavity. The efficient reverse-burning boiler has the advantages of being high in heat utilization ratio, energy-saving and environment-friendly.
Description
Technical field
The utility model relates to a kind of boiler, is specifically related to a kind of efficient back firing boiler.
Background technology
To be the heat energy that utilizes fuel or other energy be heated as the equipment of hot water or steam with water to boiler, and back firing boiler wherein mainly is to utilize coal water heating back to be supplied with place such as bathroom to use.The common structure that adopts of back firing boiler is at present: be provided with furnace internal-lining in the stove outer covering, be the folder chamber between stove outer covering and the furnace internal-lining, be provided with down from the bottom to top cold water fire grate (or stove thin bamboo strip) in the furnace internal-lining, last cold water fire grate, be lower hearth between cold water fire grate (or stove thin bamboo strip) and the last cold water fire grate down, on be upper furnace, last cold water fire grate wherein is coated in the refractory material, the refractory material of last cold water fire grate and coating, its axial section is that the top is the sub-shape of semicircular door, this design, can only be in upper furnace with the heat energy shelves of a part, most of heat energy will be transmitted in the chamber on furnace internal-lining top by refractory material, and these heats will be discharged from the chimney that is arranged at the boiler top, not only surrounding environment be caused thermal pollution, what is more important has been wasted the energy, has strengthened user's cost expenditure simultaneously.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of efficient back firing boiler, and the heat energy in the burner hearth is fully used by heat-exchanger rig, and the utilization efficiency of heat energy of boiler is greatly improved.
The utility model is achieved through the following technical solutions:
A kind of efficient back firing boiler, comprise stove outer covering, the furnace internal-lining that is provided with in the stove outer covering, and the folder chamber between stove outer covering and the furnace internal-lining, also comprise the upper furnace that is positioned at the lower hearth top, be positioned at the upper fire-grating pipe of upper furnace, upper furnace is provided with the water leg cover cap, and the water leg cover cap is communicated with folder chamber between stove outer covering, the furnace internal-lining.
The further improvement project of the utility model is, water leg cover cap axial section is a reverse U shape, and the U-shaped two ends of reverse U shape are communicated with the folder chamber.
In order further to strengthen the combustion heat-exchange effect, upper furnace suitably can be increased, two row's upper fire-grating pipes (every grate furnace comb all is furnished with hearth door) are set in the burner hearth.
The utility model compared with prior art has following obvious advantage:
The utility model is full of the water of heat exchange owing to be provided with the water leg cover cap above upper furnace in the folder chamber of water leg cover cap, therefore, the heat energy that upper furnace produces is almost all absorbed by the water in the folder chamber.Through facts have proved, heat energy utilization rate of the present utility model improves more than 30 ﹪ than going up the structural design that the cold water fire grate is coated in the refractory material.
The utlity model has the advantage of energy-saving and environmental protection.
