Description

A kind of pressure less high temperature steam boiler

The utility model relates to a kind of steam boiler, exactly is a kind of pressure less high temperature steam boiler.

Rapid development along with national economy, industrial fast development, the demand of boiler is increasing, the boiler of present various kind, specification is constantly introduced to the market, though people have done in various degree improvement on energy-conservation, efficient but are desirable not enough, bigger defective is the hidden danger that high temperature, high-pressure boiler always exist blast, can not ensure safety in production.

The purpose of this utility model provides no high pressure in a kind of stove, can avoid boiler explosion accident to take place, and ensures safety in production and thermal efficiency height fuel-saving pressure less high temperature steam boiler.

The purpose of this utility model is realized by following technical scheme.

The utility model is made up of furnace shell, combustion chamber, water tank and flue, it is characterized in that:

A, furnace shell internal upper part are provided with water tank, and the bottom is provided with the combustion chamber, and thermal insulation layer is arranged all around;

Be provided with fire grate in b, the combustion chamber, fire grate is by the water pipe of some joining water box and place one " U " type pipe that is communicated with tracheae to form therebetween;

The flue of one logical combustion chamber is arranged in c, the water tank, a tracheae is arranged in the flue, flue upper side wall joining water box top is passed in its upper end, and the lower end is communicated with " U " type Guan Yiduan, the perpendicular pneumatic tube that has outside the straight-through casing of water tank upper.

" U " type pipe other end of connectivity trachea is communicated with air supply pipe, and the air supply pipe middle part is communicated with water tank, and the air supply pipe upper end is provided with vapour booster pump.

During use, fuel is placed on the fire grate in the combustion chamber burning water pipe of fire grate is heated cause that water heats up in it, make water intensification gasification in the water tank by the heat conduction, produce steam, for people to use by the air supply pipe discharge again by " U " type pipe of tracheae in the middle of fire grate, the air pressure in the water tank is by straight-through its outer pneumatic tube control.

The utility model has the advantages that because the steam after the heating is carried out post bake and heated up by tracheae " U " type pipe of flowing through, so more existing Industrial Boiler vapor (steam) temperature height, general vapor (steam) temperature can be up to 300 ℃-600 ℃, so thermal efficiency height, place in the combustion chamber because of fire grate again, water in the fire grate water pipe not only can heat from top to bottom by the fuel that is placed on the fire grate, also can be by staying the fuel under fire grate to heat from bottom to top, thereby energy savings effectively, moreover water tank upper is provided with straight-through its outer pneumatic tube control water tank internal gas pressure, thereby got rid of the hidden danger of boiler, guaranteed safety in production.

Another advantage of the present utility model is reasonable in design, and is simple in structure, with low cost.

Fig. 1 is the utility model structural representation.

Fig. 2 is the fire grate structure schematic diagram.

By the following examples, in conjunction with the accompanying drawings, the utility model is done to describe further.

Embodiment 1:

(referring to Fig. 1,2) adopt aluminium to make furnace shell 1, add one deck thermal insulation layer 5 all around, furnace shell 1 internal upper part is put water tank 3, and combustion chamber 2 is established in the bottom, establish fire grate 6 in the combustion chamber 2, fire grate 6 is made up of with " U " type pipes 9 that are communicated with tracheae 8 putting water pipe 7 centres the water pipe 7 of some joining water box, and " U " type pipe other end is communicated with air supply pipe 11, and air supply pipe 11 middle parts are communicated with water tank, one valve 13 is housed on it, and the vapour booster pump 12 that control externally supplies steam is equipped with in the air supply pipe upper end.The flue 4 of one logical combustion chamber is arranged in the water tank 3, a tracheae 8 is arranged in the flue, flue upper side wall joining water box top is passed in its upper end, and the lower end is communicated with " U " type pipe 9 one ends.The perpendicular pneumatic tube 10 that has outside the straight-through casing in water tank 3 tops.Check-valves 14 and warning whistle 15 also are equipped with in water tank 3 tops in addition." U " type pipe port is equipped with one and is used for the gate valve 16 that steam produces preceding draining.2 bottoms, combustion chamber, one side also be equipped with one be convenient to keep in repair, change parts send out plate 17 blue.
