Description

Form the vertical drinking water boiler of steam of the vertical reentrant pathway of flue gas and steam heating cavity

Technical field

The utility model belongs to heating art, is specifically related to the drinking water boiler generating superheated vapour.

Background technology

For reducing the consumption of non-renewable energy resources, the biological particles Substitute coal of China's vegetable material such as popularization agricultural crop straw compacting is as greatly, the fuel of arcola, but its caloric value is on the low side not as good as coal furnace temperature, on the other hand, the furnace shell that the existing water jacket that surrounded by steel plate and grey room are formed, be horizontally arranged in the heat exchanger tube in intermediate water chamber, water jacket inner space furnace shell side, fire grate in furnace shell, above fire grate combustion chamber composition the vertical drinking water boiler of steam, flame and flue gas are all the water vapours that water in the process once risen in heating water jacket and heat exchanger tube and ascension go out the water surface.Flue gas and water and water vapour transfer path short, low because of biological particles calorific value again, fuel thermal energy windage is also many, the water vapour generated is heated up slow, limiting temperature is low, the fuel using biological particles as above-mentioned drinking water boiler, the instructions for use of more difficult satisfied production superheated vapour.

Utility model content

The purpose of this utility model is to provide a kind of vertical drinking water boiler of steam forming the vertical reentrant pathway of flue gas and steam heating cavity, is main fuel with biological particles, the aforementioned deficiency that the vertical drinking water boiler overcoming existing production superheated steam exists.

The vertical drinking water boiler of steam of the present utility model comprises: the furnace body outer wall and the inwall that surround water jacket, be positioned at the fire grate of the combustion chamber of water jacket inner chamber bottom, lower end, combustion chamber, the horizontal heat exchanger tube of connection water interlayer that beyond the grey room below fire grate, water jacket inner combustion chamber, part is arranged, the smoke exhaust pipe of water jacket upper end, the water-level gauge being welded on filler pipe joint and blowoff valve joint on outer wall, being arranged on upper of furnace body.The improvement done is: several times strengthen the lateral dimensions of body of heater, amplify in water jacket and direction is provided with water interlayer and the flue gas partition by mouth, formed and flue gas is vertically turned back the transversely arranged water jacket group of current multistage, combustion chamber is reserved as first section of water jacket bottom selected, top is established, the steam heating calandria of lower leaf arrangement, in one end of steam heating calandria with a box body by the port closed of whole steam heating calandria same with in the cavity of combustion chamber isolated, at the other end of steam comb, use, lower two box bodys or with the box body of median septum by upper, lower floor's steam heating calandria port is enclosed in respectively, in lower two cavitys, upper, lower floor's steam heating calandria is closed connection on a cavity of one end respectively and is passed water jacket inwall and the emersed steam input pipe of port, another cavity connects the steam output pipe passing body of heater.Establish with in the middle part between steam-heating pipe and first section of water jacket following section of water jacket the horizontal heat exchanger tube being communicated with water interlayer first section of water jacket combustion chamber.Smoke exhaust pipe is located at the upper end of latter end water jacket.Flue gas is flowed through to the partition of its lower end, flue gas is located in the grey room on the partition of partition lower end or beyond partition by mouth, flue gas is located to the structure in grey room by mouth, grey room need be carried out grouping isolation.

Running of the present utility model is: water filling in furnace shell, the water surface and furnace shell top reserve spacing as steam cavity volume and first heating clamber, during fuel combustion, the upper end of the water jacket of combustion chamber is extremely surrounded in flame and flue gas ascension, by the passage of the upper end, intermediate layer of water-flowing next door between the water jacket that is adjacent, enter the descending water jacket of flue gas, after flue gas comes downwards to the lower end of this water jacket, the grey room isolated with atmospheric exposure shared by the passage of the lower end, intermediate layer of water-flowing next door between the next stage water jacket that is adjacent or the descending water jacket of flue gas and next stage water jacket, proceed to next stage water jacket, the water jacket entering this section is up, discharge from smoke exhaust pipe or enter one section of water jacket again.By the water in the flame of water jacket and flue gas jacket sidewall and heat exchanger tube to boiling, gather in the steam cavity volume of the water vapour generated above the water surface, along with the steam pressure in vapor chamber be increased over atmospheric pressure time, water vapour in cavity volume enters steam input pipe under the effect of the pressure and form downward vapor stream in pipe, vapor stream to enter after after enclosed cavity dispersion train through the steam comb of port in this enclosed cavity, after flowing to the other end, turn back under the constraint of enclosed box body, flow through another part steam comb, after the enclosed cavity of this some vapor comb port converges, steam outlet through drinking water boiler transports to steam application apparatus or place.

Good effect of the present utility model is: when not increasing body of heater height, is added to the heat exchange space of flame and flue gas and water, improves the utilization rate of heat value of fuel.By being located at the steam comb that the steam that generates in the pressure stove in the water jacket of combuster passes.Improve the tapping temperature of steam.Using biological particles as fuel, the steam of the warmer be rapidly heated can be produced.
