Abstract
The utility model provides a water heating boiler at atmosphere and with high chamber and closed arrangement of pipelines, comprising an inner boiler casing, an outer boiler casing, a water inlet pipe, a water outlet pipe, a boiler chamber, a heating pipe bundle, a throat pipe, a towering pipe and auxiliary equipment. The volume of the boiler chamber is enlarged; the top of the boiler chamber is staggerly provided with two to four rows of radiation heating pipe banks which are formed into 15 DEG with the horizontal line; the number is larger than the 1/3 of the pipe of the whole heating surface of the boiler; the high temperature fume in the boiler chamber can be absorbed fully. Simultaneously, because of the impact effect of the fume in the boiler chamber and the radiation heating pipe banks, before the fume enters the throat pipe, the soot particles in the fume are settled in the boiler chamber to be burnt fully. Therefore, compared with the ordinary boiler at atmosphere, the heat efficiency and the discharge concentration of the fume of the utility model are improved obviously.
Description
The utility model relates to a kind of improved normal-pressure hot-water boiler.
At present general normal-pressure hot-water boiler mainly is made up of be heated tube bank, trunnion, impact tube and appurtenances of interior outer boiler hull, radiation heated calandria, interlayer board, convection current.Although this boiler form difference, specification is different, all has compact conformation, advantage such as easy to manufacture, easy to operate.Also ubiquity following deficiency simultaneously, because combustion space is little, the radiation heated calandria is few, heat can not get abundant absorption, and boiler thermal output does not increase, therefore, most applying units adopt the building of the less heating area of boiler supplying of capacity bigger than normal, exist the situation of " low load with strong power ".
The purpose of this utility model is by improving the boiler internal topology layout, rationally adjust each heating surface ratio of boiler, make boiler that heat energy is provided to greatest extent, improve the thermal efficiency, reducing heat loss, for the user provides a kind of energy-efficient normal-pressure hot-water boiler.
For achieving the above object, the utility model has been taked following measure on the basis of existing boiler structure: grate area is increased by 1/3 with the normal-pressure boiler of capacity, furnace height increases 1/3 with the normal-pressure boiler of capacity, become the width of cloth at 15 ° of angles to penetrate heated calandria be staggered 2-4 row of roof of the furnace with level, its quantity is greater than 1/3 of the whole heating surface pipes of boiler, unaffected for guaranteeing coal-fired ignition temperature, the bottom width of cloth is penetrated the distance of heated calandria and fire grate greater than 800mm, to keep the smooth combustion in coal seam.Like this, make burner hearth reach big volume, high swing pipe, solid matter pipe, both guaranteed the abundant burning in coal seam in the burner hearth, guaranteed the abundant absorption of heat in the burner hearth again.
After above-mentioned improvement, because upper furnace is covered with the width of cloth and penetrates heated calandria, high-temperature flue gas can fully be absorbed, simultaneously because the collision effect of high-temperature flue gas and heated calandria, before entering trunnion, soot particle in the flue gas can be deposited in the burner hearth, makes full combustion of fuel, so the thermal efficiency of this boiler and all more common normal-pressure boiler of smoke dust discharge concentration have clear improvement.
Below in conjunction with accompanying drawing this practicality is newly further described.
Accompanying drawing is the cutaway view of the high burner hearth solid matter of the utility model pipe normal-pressure hot-water boiler.
Four rows that are being staggered in the burner hearth 2 of this boiler become 15 ° the width of cloth to penetrate heated calandria 3 with level, this part pipe has constituted the main width of cloth of boiler and has penetrated heating surface, the width of cloth is penetrated the heating surface comb and is accounted for 1/3 of whole heating surface pipe sums, establish a smoke baffle plate 7 in the upper back of burner hearth, smoke-box is divided into vertical smoke-box and horizontal smoke-box, lower furnace portion is an ashcan 1, high-temperature flue gas washes away the width of cloth in burner hearth 2 penetrate heated calandria 3 after, turn back downwards, wherein the soot particle in the flue gas is deposited in the burner hearth and burns away, it is burning chamber 5 that flue gas enters vertical smoke-box through trunnion 4, and upwards wash away burning chamber's convection calandria 6 (at this moment, because flow velocity reduces suddenly, micronic dust lands once more in burning chamber's bottom collection ashcan in the flue gas), high-temperature flue gas enters horizontal smoke-box 8, with after the 9 abundant heat exchange of convection calandria in the smoke-box (hindered settling once more of the micronic dust in the flue gas), enters chimney through impact tube 10.The utility model boiler is because abundant with each heating surface heat exchange, and exhaust gas temperature obviously reduces, and boiler thermal output obviously improves.
Claims (1)
1, a kind of high burner hearth solid matter pipe normal-pressure hot-water boiler, comprise that interior outer boiler hull, burner hearth, water inlet pipe and water outlet pipe, the width of cloth penetrate heated calandria, convection current be heated tube bank, trunnion, impact tube and auxiliary equipment, it is characterized in that, grate area increases by 1/3 than the boiler with capacity, furnace height increases 1/3 with the normal-pressure boiler of capacity, become 15 ° the width of cloth to penetrate heated calandria be staggered 2-4 row of roof of the furnace with level, its quantity is greater than 1/3 of the whole heating surface pipes of boiler, and the width of cloth of the bottom is penetrated the distance of heated calandria and fire grate greater than 800mm.
