Abstract
The utility model discloses a direct combustion and water injection type boiler, which does not alter integral structure of the original boiler and just changes the original furnace arch into water injection to connect the front and the back of arches with a boiler barrel and a lower connecting box to form a hot and cold circulation system so as to add heating elements, lower heat loss rate, and save coal by 40%. In addition, owing to adding an air heating apparatus, wind entering a boiler chamber becomes hot air to ensure normal temperature in the boiler chamber and save a great amount of fuel.
Description
The utility model relates to a kind of boiler, particularly a kind of with after the chimney arch water flowing as the direct-fired boiler of a kind of original paper that is heated.
How our common boiler that adopts, its model and form change and all have chimney arch (comprising: face arch, hogging, rear arch) in its burner hearth at present, their effect is the savings heats, adjust combustion centre, improve the temperature of burner hearth, quicken new coal combustion, next is the prolong smoke flow process, promotes fully burning; The arch that we adopted is to adopt reinforcing bar, refractory cement, refractory aggregate now, and fire-resistant fines is made, and its weak point is itself can not conduct heat to the outside as the original paper that is heated to come, and has caused a large amount of heat loss.The air themperature that original in addition its air blast of boiler is sent at burner hearth bottom lower (being the temperature of winter environment basically), because the low temperature that has reduced in the stove of temperature, need to consume the normal temperature that a large amount of fuel could guarantee that burner hearth is interior, so also caused a large amount of energy loss.
The purpose of this utility model is will provide a kind of to make arch into the water flowing arch, directly burns in burner hearth as the original paper that is heated, and the wind that air blast is sent to is the New-type boiler of hot blast.
The purpose of this utility model is to realize like this, this direct-burned water-through arch boiler is by drum, cold wall pipe, lower collecting box, lower collecting box communicating pipe, the water flowing arch, tube connector, critical pieces such as air heating apparatus are formed, it is the structure that has only changed arch on the basis of original boiler, solid arch is made into the arch of water flowing, be that the water flowing arch is designed to cuboid, short side direction has radian, the water flowing arch is provided with three water reserves, right-hand member three water reserves has three tube connectors respectively and links to each other with drum, left end has three tube connectors respectively and links to each other with lower collecting box communicating pipe, the front and back of arch and drum and lower collecting box are connected to form cooling and heating circulation system, have reinforcement on the water flowing arch to prevent that heating the back expands, this water flowing arch is to adopt the shell plate of 24K (14-16mm is thick) to be welded.It is except playing the heat accumulation of chimney arch, improve furnace temperature, promote fully burning, outside the effect such as prolong smoke flow process, played simultaneously and directly made the water increase gas production of being heated, improve the effect of water temperature, a floss hole place in burner hearth is provided with an air heating apparatus in addition, there was four communicating pipes on these device both sides in the middle of having two connection casees, have two air turnover pipes at the two ends that are communicated with case, one links to each other with air blast, and another root leads to burner hearth bottom, continuously supplies the purpose that enough hot-airs have so just been finished invention in burner hearth.
The utility model is changed system into the water flowing arch with chimney arch (comprising: face arch, hogging, rear arch), and is provided with air heating apparatus owing to adopted above-mentioned structure, improve the temperature of stove, increased the absorption of heat, saved the energy, this arch economizes on coal 40% after changing the water flowing experiment into.
Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.
Fig. 1 is a direct-burned water-through arch boiler overall structure schematic diagram;
Fig. 2 is a direct-burned water-through arch boiler water flowing arch structure schematic diagram;
Fig. 3 is a direct-burned water-through arch boiler air heating apparatus structural representation.
Describe concrete structure of the present utility model and operating position in detail below in conjunction with accompanying drawing.This direct-burned water-through arch boiler is by drum 1, cold wall pipe 2, lower collecting box 3, lower collecting box communicating pipe 4, water flowing arch 5, tube connector 6, air heating apparatus 7 critical pieces such as grade are formed, it is the structure that has only changed arch on the basis of original boiler, solid arch is made into the arch of water flowing, be that water flowing arch 5 is designed to cuboid, short side direction has radian, water flowing arch 5 is provided with three water reserves 8, right-hand member three water reserves 8 has three tube connectors 6 respectively and links to each other with drum 1, left end has three tube connectors 6 respectively and links to each other with lower collecting box communicating pipe 4, the front and back of arch and drum 1 and lower collecting box 3 are connected to form cooling and heating circulation system, have reinforcement 12 on the water flowing arch 5 in case go up the expansion of heating back, this water flowing arch 5 is to adopt the shell plate of 24K (14-16mm is thick) to be welded.It is except playing the heat accumulation of chimney arch, improve furnace temperature, promote fully burning, outside the effect such as prolong smoke flow process, played simultaneously water is heated, increase gas production, improve the effect of water temperature, a floss hole place in burner hearth is provided with an air heating apparatus 7 in addition, there is four communicating pipe 10 on these device both sides in the middle of having two connection casees 9, have 11, one of two air turnover pipes at the two ends that are communicated with case 9 and link to each other with air blast, another root leads to burner hearth bottom, continuously supply enough hot-airs in burner hearth, the size of three kinds of arches being changed a social system and shape are identical according to the change of shape of the model of stove and original arch but from its design concept.
