Description
Affiliated technical field
The utility model provides a kind of lower feeding coal-fired normal-pressure boiler, belongs to lower feeding coal-burning boiler technical field.
Background technology
The many upper and lower sides in the boiler back of existing lower feeding coal-burning boiler are provided with two drums, by many cross currents, and around body of heater Inner Front End combustion chamber the side's of setting water tank, the water tank upper edge has one deck water pipe to be connected with upper drum, has water inlet pipe to be connected with lower drum below the water tank.Defective is: upper drum is too far away apart from the combustion chamber, be unfavorable for absorbing heat, the side's of setting water tank is easy to generate the dead angle around in the combustion chamber, dead angle place coal-fired nonflammable or burn insufficient, waste energy, it is little around in the combustion chamber one deck water pipe endotherm area to be set, and heat utilization efficiency is not high, and its service behaviour needs further improvement.
The utility model content
The purpose of this utility model provides a kind ofly can overcome above-mentioned defective, heating surface area is big, the thermal efficiency is high, the coal-fired normal-pressure boiler of the lower feeding of excellent working performance.Its technical scheme is:
Comprise body of heater, be arranged on the drum of body of heater upper and lower side, water tank and some water pipes, it is characterized in that: upper drum is arranged in the middle of the body of heater inner top, lower drum is positioned at a side of body of heater inner combustion chamber, add the truncated cone-shaped hydroecium around in the combustion chamber, the top of combustion chamber is provided with water tank, being provided with two-layer water pipe around the upper edge of truncated cone-shaped hydroecium is connected with water tank, at water tank and upper drum, also be communicated with between two drums with the multilayer water pipe, and between the outer water pipe that truncated cone-shaped hydroecium upper edge is provided with, be connected to form seal chamber with exotic material between the outer water pipe in the whole body of heater, the top of cavity wall is provided with outlet flue, also be connected to form partition wall with exotic material at the middle one deck water pipe that is communicated with two drums, flue is left in the bottom of partition wall.
The coal-fired normal-pressure boiler of described a kind of lower feeding, the upper horizontal of combustion chamber is provided with three vertical water tanks, is communicated with between the water tank with horizontal water tube, is communicated with two-layer water pipe between the top of each water tank and the upper drum.
For realizing the coal-fired normal-pressure boiler of described a kind of lower feeding, between the seal chamber of body of heater and outer water pipe, exotic material formation, be provided with heat-insulation layer.
The coal-fired normal-pressure boiler of described a kind of lower feeding, upper drum is provided with delivery port and exhaust outlet, and lower drum is communicated with water inlet pipe.
The utility model compared with prior art has following advantage:
1, adds the truncated cone-shaped hydroecium around in the combustion chamber, make the cross section of combustion chamber rounded, avoided square water tank to produce the coal-fired nonflammable or inadequate defective of burning at dead angle, place, dead angle, saved the energy, and around the upper edge of truncated cone-shaped hydroecium, be provided with two-layer water pipe and lead to upper drum, the flame heat regulating of combustion chamber;
2, upper drum is changed by the back and is located in the middle of the body of heater inner top, has reduced the distance with the combustion chamber;
3, three water tanks are set above the combustion chamber, are communicated with between the water tank with horizontal water tube, water inlet is advanced from the water tank of both sides, enters through horizontal water tube then to be positioned at middle water tank, enters upper drum through vertical water pipe again after the heating, has strengthened endotherm area;
4, be connected to form partition wall at the middle one deck water pipe that is communicated with two drums with exotic material, flue is left in the bottom of partition wall, make flame and the ascension of cigarette elder generation in the combustion chamber, and then down return, by ascension again behind the flue, after its heat is fully absorbed by the water pipe in the body of heater, after outlet flue discharge, wherein the dust in the flue gas also falls, and has both improved the thermal efficiency, has reached the dust discharge effect again.
