Abstract

The utility model discloses a boiler which is directly heated by a water-flowing wall as a heating element instead of a fire-proof wall. The direct combustion water-flowing wall boiler is composed of main components assembled by a boiler barrel (1), cooling wall pipes (2), a lower connecting box (3), water-flowing wall monomers (4), etc. On the basis of original boilers, only the structure of the fire-proof wall is altered. The solid fire-proof wall bricked by fire-proof bricks is altered into the water-flowing wall soldered by steel plates and composed of a plurality of the water-flowing wall monomers (4). Due to the adoption of the water-flowing wall instead of the fire-proof wall, the temperature of the boiler is enhanced, the heat absorption is added, the heat efficiency is enhanced and the energy is saved. The boiler has the advantages of reasonable structure, easy installation, easy rebuilding, high safety, etc. Not only heating and heat conducting areas are enlarged, but also the circulating mode, the boiler type and the inner structure of the original boilers are kept unchanged.

Description

The direct combustion and water wall type hot air boiler

The utility model relates to and a kind ofly replaces refractory wall with the water flowing wall, and with it as the direct-fired boiler of a kind of original paper that is heated.

Our common boiler that adopts at present, no matter how its model and form change, refractory wall has all been built in its cold wall pipe outside, its effect is the savings heats, improve the temperature of burner hearth, prevent scattering and disappearing of heat, its weak point is itself can not conduct heat to the outside as the original paper that is heated to come, and has caused the loss of lot of energy.

The purpose of this utility model is will provide a kind of to make refractory wall into the water flowing wall, directly burns as the original paper that is heated, and the wind that machine is sent in the drum is the New-type boiler of hot blast.

The purpose of this utility model is achieved in that this directly burns water flowing wall boiler is by drum, cold wall pipe, lower collecting box, critical pieces such as water flowing wall monomer assemble, it is the structure that only changes refractory wall on the basis of original boiler, to make a plurality of water flowing wall monomers of being welded into steel plate with the solid refractory wall that refractory brick is built into into, each water flowing wall monomer is arranged on the periphery of cold wall pipe, and the composition water flowing wall that arrays from left to right, the top of water flowing wall monomer connects by bend pipe and drum flange, be connected with the lower collecting box flange below by connecting tube, have reinforcement on each water flowing wall monomer to prevent that heating the back expands, it is except playing refractory wall savings heat like this, improve the temperature of burner hearth, prevent outside the scattering and disappearing of heat, play simultaneously and directly make the water increase gas production of being heated, improve the effect of water temperature, thereby reached this bright purpose.

The utility model is owing to adopt the water flowing wall to replace refractory wall, improved the temperature of stove, increase the absorption of heat, improved the thermal efficiency, saved the energy, have rational in infrastructure simultaneously, transform easy for installation, advantage such as security is good, it has not only increased and has been heated and heat-conducting area but also kept the operation endless form of former boiler constant, the type of furnace is constant, and internal structure is constant.

Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.

Fig. 1 is a direct combustion and water wall type hot air boiler overall structure schematic diagram.

Describe the novel specific embodiment of this usefulness in detail below in conjunction with accompanying drawing: this directly burns water flowing wall boiler is by drum 1, cold wall pipe 2, lower collecting box 3, water flowing wall monomer 4 critical pieces such as grade assemble, it is the structure that only changes refractory wall on the basis of original boiler, the water flowing wall that a plurality of water flowing wall monomers 4 that will make to be welded into steel plate with the solid refractory wall that refractory brick is built into into are formed, its water flowing wall monomer 4 is to be welded with the thick steel plate of 20G (10～14), each water flowing wall monomer 4 is arranged on the periphery of cold wall pipe 2, and the composition water flowing wall that arrays from left to right, building insulating brick around the whole water flowing wall.The top of water flowing wall monomer 4 connects by bend pipe 5 and drum 1 flange, be connected with lower collecting box 3 flanges below by connecting tube 6, have reinforcement 7 on each water flowing wall monomer 4 to prevent that heating the back expands, it is except playing refractory wall savings heat like this, improve the temperature of burner hearth, prevent outside the scattering and disappearing of heat, play simultaneously and directly make the water increase gas production of being heated, improve the effect of water temperature, thereby reached this bright purpose.
