Efficient non-pressure hot water and steam dual-purpose boiler
Technical field
The present invention relates to non-pressure coal-fired multipurpose furnace, belong to the boiler technology field.The present invention specifically is a kind of efficient non-pressure hot water and steam dual-purpose boiler.
Background technology
Hot water and the steam two-purpose boiler that uses on the market is steam boiler in fact at present, its heat exchange is that flue gas and heated medium directly carry out heat exchange generation steam, steam boiler can not be realized the steam alliance, needs special steam supply equipment during promptly with its steam supply, needs special water tank during water supply.And all need independent heating, during consumption energy consumption.In order to solve this technical problem, on March 4th, 2009, Chinese utility model patent notification number CN201203253Y disclosed a kind of dual purpose steam water boiler, comprise vertical steam boiler, heat exchanger tube, heat exchanger tube is arranged at vertical steam boiler top by gripper shoe, the heat exchanger tube both sides are respectively equipped with end socket and Inlet and outlet water end socket, are respectively equipped with backhaul baffle plate and water inlet pipe and water outlet pipe at the Inlet and outlet water seal head end.Though this boiler is realized the steam alliance, the independently heat exchanger tube of heat production water and the independently steam boiler of producing steam, heat exchanger tube is at the horizontal right horizontal stroke in a left side, stove the inside, stop up burning gallery, make burning not smooth, strong air blast and exhausting must be installed, structure is obviously complicated.Simultaneously, heat transfer efficiency neither be very high.
Summary of the invention
At the above-mentioned defective that exists in the prior art, the present invention aims to provide a kind of simple in structure, energy-conservation, efficient non-pressure hot water and steam dual-purpose boiler that heat transfer efficiency is high, uses the present invention, can produce steam and hot water separately.
The present invention adopts following technical proposals to realize: a kind of efficient non-pressure hot water and steam dual-purpose boiler, comprise stove and main stove down, and main stove is placed in down the top of stove; Following stove has the burner hearth of a band water jacket, puts into honeycomb briquette or little coal briquette in the burner hearth; Burner hearth bottom has hand movable grate, burner hearth air door and connect blower tube; Water inlet pipe and blow-off pipe are arranged at the water jacket bottom of following stove; Above-mentioned main stove is mainly by main water box, and the welding of the damping pyrotechnics bellows chamber one of two or more series connection in pyrotechnics pipe and the main water box is formed up and down; Between the water jacket of following stove and the main water box cross current of connection is arranged; On the dome head of described main water box top smoke exhaust pipe is arranged, the hot-water line outlet, steam pipe and minute-pressure safety valve, main water box has water surface line of demarcation in the upper end, there is the water-level probe mouth side outside of the corresponding main water box in top, water surface line of demarcation, and there is the temp probe mouth side outside of the corresponding main water box in below, water surface line of demarcation; The main water box bottom surface is the heat affected zone of an indent, described damping pyrotechnics bellows chamber is to use two block sizes up and down, the enclosure body of the relative seam of metallic plate of the parabolic shape of shape unanimity or square concave shape is communicated with sparse equally distributed pyrotechnics pipeline more than 5 between the adjacent damping pyrotechnics bellows chamber; And a relative complete damping pyrotechnics bellows chamber, between the pyrotechnics pipeline through hole up and down not over against, the arbitrary sectional area of damping pyrotechnics bellows chamber level is greater than the area of described 5 above pyrotechnics pipe level cross section sums; The following pyrotechnics pipeline of a damping pyrotechnics bellows chamber connects the heat affected zone of main water box bottom surface indent bottom, and topmost the last metallic plate connection smoke exhaust pipe of a damping pyrotechnics bellows chamber passes from the central authorities of main water box heading shape end socket.
The present invention puts into honeycomb briquette or little coal briquette, and when burning, the size of fire is by the burner hearth air door and the air blast control of bottom.Water in the waste heat heating lower hearth water jacket of following stove burner hearth fire coal.The damping pyrotechnics bellows chamber that coal-fired main fire passes through the pyrotechnics tube passage and connects up and down, master's fire stream is blocked by damping pyrotechnics bellows chamber the time slowly passes through; It is long that the coal-fired pyrotechnics that produces is trapped in the stove time by damping pyrotechnics bellows chamber, is beneficial to heat and fully absorbed by bellows chamber metallic plate and pyrotechnics pipeline, heats the water of main stove rapidly, and cigarette is discharged out of the furnace by smoke exhaust pipe.And cinder is discharged by hand movable grate.Water stream channel during heat production water is: cold water → water inlet pipe → hearth water sleeve → connection water pipe → main water box heat exchange → hot-water line outlet.
If when wanting steam, as long as it is following that the water of main water box is reduced to water surface line of demarcation, steam will constantly be assembled on main water box top, discharges continually by steam pipe.
Furnace roof is equipped with the minute-pressure safety valve, guarantees safety.
So this stove both can be made water heater, can make steam oven again, but in use, switch can not be installed at steam pipe and hot-water line outlet.
But the also spontaneous firing of damping pyrotechnics bellows chamber of the present invention's design designs a plurality of resistance pyrotechnics bellows chambers, and its purpose allows heat absorption more abundant exactly.Bellows chamber two ends pyrotechnics pipe is staggered to link to each other, and also is straight-through in order to reduce pyrotechnics.
Compared with the prior art, the present invention has following characteristics: compact conformation, and the easy-to-clean ash maintenance, thermal efficiency height, energy-conserving and environment-protective, flexible to operation; Can realize mutual impregnable steam and hot water on same stove, the departments such as bathing pool, restaurant, hotel, hospital that are very suitable for use.
