Abstract

The utility model discloses a coal-fired pressureless multi-purpose steam boiler, which comprises a furnace body, a chamber and a heating fire pipe. The key points lay in that the furnace body consists of an upper furnace body and a lower furnace body. All round of the chamber of the lower furnace body is equipped with a water jacket. The heating fire pipe communicates with the water jacket and the upper end of the water jacket communicates with the steam pipe through a gas outlet. The water heater is equipped inside the upper furnace body. About 1 to 5 longitudinal flue heating pipes communicating with the flue outlet and flue are equipped in the middle of the water heater. The exhaust pipe and the water charge line communicating with the water charge fountain are equipped on the top of the water heater; and the hot water valve is equipped on the bottom of the water heater. The insulating layer is equipped between the furnace body and the water heater, also among the water jacket. The utility model has the advantages of reasonable design, novel structure, safety, saving energy and many functions. From firing to ejecting only takes 10 minutes steam. The temperature of the water in the water heater can keep above 40 Celsius system for 12 hours after extinguishing fire. The pressureless steam boil can be spread to use in the places such as home, school, dining hall, etc.

Description

A kind of coal-fired steam of pressure multipurpose furnace that do not have

Affiliated technical field

The utility model relates to the steam boiler technical field, the civilian steam oven of vertical double that specifically a kind of fire-tube type and water pipe type combine.

Background technology

The no pressure steam boiler of fire coal of the prior art, though kind is a lot, structure more complicated mostly, it is very inconvenient to operate, and energy input is also bigger, and waste heat is difficult to make full use of.Particularly the function ratio of some pressure-less boiler is more single, and the heating air feed is used boiling water with life, and both often can not take into account mutually.

Summary of the invention

In order to overcome the deficiency that existing coal-fired no pressure steam boiler structurally exists, the utility model provide a kind of simple in structure, energy consumption is low, the fire coal of multi-use does not have pressure steam multipurpose furnace.

The technical scheme that its technical problem that solves the utility model adopts is: this coal-fired steam of the pressure multipurpose furnace that do not have, comprise body of heater and be arranged on the outlet flue at body of heater top and the combustion chamber of body of heater bottom, fire grate, coal feed point, ash accepting box and supporting leg, be provided with laterally staggered heating fire-tube in the combustion chamber, be that mainly said body of heater is connected and composed by lower furnace body and upper furnace body two parts, leave flue between lower furnace body and the upper furnace body, be provided with water jacket around the lower furnace body combustion chamber, heating fire-tube is connected with water jacket, the upper end of water jacket connects steam pipe by the gas outlet, the automatic water replenishing device that the lower end is provided with sewage draining exit and is connected with water-adding bucket and water jacket; In upper furnace body, be provided with boiler, the centre of boiler is provided with 1～5 longitudinally and the flue heating tube that is connected with top outlet flue and following flue, the filler pipe that the top of boiler is provided with blast pipe and is connected with water-adding bucket, the bottom is provided with hot water valve; On the furnace body wall of lower flue on the boiler, be respectively equipped with two cleaning doors up and down; Between body of heater and boiler, water jacket, be provided with heat-insulation layer.

Fire coal according to the utility model design does not have the steam of pressure multipurpose furnace, and main advantage is a novel structure, energy-saving safe, multi-use.On the one hand, do not have to press the vertical double structure owing to adopted, lower furnace body to be producing steam, and the steam that utilizes burning to produce can solve life heating, steamed sweet bun, cook etc.Upper furnace body utilizes the boiling water of upper furnace body can solve shower, drinks boiling water etc. so that the boiling water of life usefulness to be provided.On the other hand, be provided with heat-insulation layer between body of heater and boiler, water jacket, so the heat insulation effect of boiler is relatively good, ceased fire 12 hours, the water temperature in the boiler still can remain on more than 40 ℃.Simultaneously, because in the boiler of upper furnace body, be provided with 1～5 longitudinally and the flue heating tube that is connected with outlet flue, in the lower furnace body combustion chamber, be provided with heating fire-tube, and be connected, so igniting is convenient with water jacket, quick heating, lighting a fire just can spray steam in 10 minutes.
