Description
Technical field
The utility model belongs to the coal-burned industrial boiler field, and being specifically related to a kind of is fuel with various other water-coal-slurry of level, for generation of the vertical type module water-coal-slurry corner tube boiler of steam.
Background technology
The energy resource structure of China is based on coal, and in the following long duration, coal-burned industrial boiler will be the leading products of Industrial Boiler.
Traditional industry coal-boiler is based on grate firing boiler, and shortcoming is that efficiency of combustion is low, and is seriously polluted, is difficult to satisfy energy-saving and emission-reduction and pollutant emission requirement.
Cool water mixture burning is one of high performance clean burning mode of coal, and its efficiency of combustion can reach more than 98%, is the combustion technology of a maturation, is widely used at large-sized station boiler.In recent years, the burning of water-coal-slurry powder also is applied on Industrial Boiler, all adopts the two drum bulk water pipe boiler structures of SHS type or the two drum water pipe structures of D type.But there is certain deficiency:
1) burning is even inadequately, and the front and back temperature difference is bigger, is unfavorable for reducing NO
XContent.
2) load regulation range is little, can only use single rank coal water slurry fuel.
3) Boiler Ash, slag cleaning inconvenience.
4) boiler steel, furnace wall material consumption are big.
5) floor space big, civil engineering in boiler room is set as high.
6) the boiler seal performance is not good, the brick wall inleakage is big, boiler heat loss big, the air-introduced machine power consumption is big.
7) the two drum bulk water pipe boiler manufacturings of SHS type are installed inconvenient.
Summary of the invention
The utility model provides a kind of novel vertical type module water-coal-slurry corner tube boiler at the deficiency of existing bulk water pipe boiler and horizontal coal water slurry boiler.
The utility model is achieved through the following technical solutions: a kind of vertical type module water-coal-slurry corner tube boiler, comprise boiler body, burner hearth, burner, stable burning room, furnace hopper, air preheater, economizer, convection bank, upper collecting chamber, top collection case, drum and next part case, described next part case is arranged on the bottom of boiler body; Described upper collecting chamber and top collection case are arranged on the top of boiler body, and by vapour communicating pipe UNICOM; It is anterior to it is characterized in that described stable burning room is arranged under the boiler body; Described burner is arranged on the front wall of described stable burning room; Described boiler body comprises 4 down-comers and the fin panel casing that is arranged in four jiaos; The two ends of described down-comer and fin panel casing respectively with described upper collecting chamber and next part case UNICOM; Described convection bank is arranged on the outside of described fin panel casing, top and pot thorax outlet flue UNICOM, the end UNICOM of bottom and described air preheater; The top UNICOM of described economizer and described air preheater; Described furnace hopper is arranged on the bottom of boiler body.
Vertical type module water-coal-slurry corner tube boiler of the present utility model, various other water-coal-slurry of level spray into vertical L shaped burner hearth by the front wall firing device, simultaneously, the high temperature air after air preheater heating also enters burner and water-coal-slurry and is mixed into burner hearth and carries out fierce suspension combustion.
High-temperature flue gas behind the burner hearth combustion heat-exchange enters convection bank downwards for 180 ° from the turnover of burner hearth outlet flue and carries out heat convection, and flue gas enters flue gas purification system after entering air preheater and economizer successively again.
The utlity model has following advantage:
1) boiler body adopts vertical corner tube type structural configuration, arranges 4 heavy caliber down-comers for four jiaos, and this down-comer namely is water circulation pipe, also support simultaneously whole boiler, therefore do not need to establish in addition supporting steel frame, compact overall structure, profile are arranged simply, floor space is little, and the steel consumption is low.
2) burner hearth adopts membrane wall structure, and furnace wall only needs insulation material, integral sealing, good heat insulating, and boiler leaks out few, and the air-introduced machine power consumption is few.
3) boiler divides several big film pieces such as stable burning room, furnace hopper, drum, convection bank, fin panel casing to make and install, and efficiently solves the problem of boiler transportation clearance restriction boiler capacity development, and simple and fast is installed in the boiler manufacturing.
4) boiler membrane wall structure intensity height, boiler operatiopn is reliable.
5) but the comprehensive maintain and replace of boiler, the advantage that tool maintenance is easy.
6) boiler water cycle pressure reduction is big, and safe water circulation is reliable.
7) upper collecting chamber is connected with vapour communicating pipe with top collection case and inserts drum simultaneously, and steam water interface enters upper collecting chamber from heating surface, and in upper collecting chamber the carbonated drink pre-separation takes place, and steam collects the air space that case enters drum top through vapour communicating pipe to pushing up.Because upper collecting chamber all inserts at the high water level place of drum, then steam does not directly insert drum by the hydrospace, thereby has avoided the generation of foam, adds the steam that enters drum and has carried out pre-separation, therefore, has improved the quality of steam greatly.
As further improvement of the utility model, described burner is single or multiple burner arrangement.The benefit of a plurality of burner arrangement is that each burner can control separately, improves the stability of burning and the adjusting function of load greatly, can use two or more fuel simultaneously.
Further improve as of the present utility model, the flag facial canal is adopted in described convection bank again, and described flag facial canal press that certain angle is vertical to be arranged along row, the heating surface abundance, circulation reliably, sweep of gases is smooth and easy, is difficult for dust stratification, prolonged boiler service life.
Further improve as of the present utility model, described preceding bottom in burner hearth is provided with the one-level secondary air channel of combustion-supporting usefulness.Describedly be respectively equipped with secondary secondary air channel combustion-supporting and that denitration is used in the left and right sides, burner hearth middle part.Adopt grading combustion technology, send into two-stage secondary wind in the burner hearth successively, whole temperature field is even, the generation that can guarantee effectively to stop the burner hearth coking under the clean-burning prerequisite of uncombusted product and reduce nitrogen oxide.
