Abstract
The utility model relates to a forced circulation cornue type water heating boiler. The water circulation of the boiler adopts a reliable forced circulation structure with reasonable layout; the water flows at a reasonable speed along a certain direction by means of a baffle plate in a collecting box depending on a circulation water pump pressure head. The tail of the boiler adopts a banner type heating surface with simple preparation process, high heat transferring efficiency and safe water circulation. The utility model does not need special manufacturing equipment and has the advantage of compact structure; the volume of the boiler is only equivalent to half of the volume in the same type.
Description
The utility model belongs to a kind of solid-fuelled combustion apparatus, particularly a kind of forced circulation corner-tube hot-water boiler.
At present, the back-end surfaces structure of forced-circulation hot water boiler is upper and lower collection case, and (being lantern bundle structure) formed in the middle part convection bank or afterbody is the coiled pipe structure, needs to be made by special special equipment, and the equipment needed thereby investment is big, complex manufacturing technology.
The purpose of this utility model is to solve above-mentioned existing existing problem, provides a kind of current connection and reasonable arrangement, the forced circulation corner-tube hot-water boiler that heat transfer efficiency is high.
The utility model is achieved in that by fire grate, boiler body and furnace wall to be formed.The upper left quarter of boiler body is provided with drum, dividing plate is set in drum and the carbonated drink balance pipe is arranged.Arch before and after in burner hearth, being furnished with, before and after arch tube respectively with the next part case at upper drum and front and back arch place, in horizontal collection case link to each other, two side water wall tubes with about go up the next part case and link to each other, the both sides upper collecting chamber links to each other with upper drum, tube connector supports drum and couples together with the next part case, and forms a tower structure with the flag formula heating surface that the rear portion is provided with.
The flag formula heating surface at rear portion is formed by two groups, and first group is single flag heating surface that in-line arrangement is arranged transversal flow, and second group of the middle part is the flag formula heating surface that double stagger arrangement is arranged.Each flag formula heating surface respectively accounts for half, be symmetrically arranged, and should group flag formula face with about go up the next part case formation closed circuit that links to each other.
Before left and right two next part casees, locate to be provided with dividing plate between several the 22nd, 23 water screen tubes; Several the 46th water screen tube places are provided with dividing plate before the left and right upper collecting chamber, and by the dividing plate that is provided with in the drum, make rear arch the 43rd locate to form the decline loop and by the front and back arch tube with in horizontal collection case, the horizontal collection case in middle back links to each other and supports an also cooling effect of rear arch.
The flue structure of boiler is made up of furnace outlet, first convection pass, dust chamber and second convection pass; Flue gas enters convection pass by furnace outlet and is moved into behind the reversal chamber 90 from top to bottom again.Turning moves upward.In the turning process, big particle relies on action of centrifugal force to drop in the expansion chamber, because that the height of expansion chamber changes the second convection pass height over to apart from flue gas is bigger, falls into expansion chamber to making a large amount of dusts break away from flue gases.
Advantage of the present utility model is, reliable forced circulation structure is adopted in the water circulation of boiler, and is rationally distributed, relies on the water circulating pump pressure head, make water along certain orientation by collection case internal partition, flow with suitable speed, boiler tail adopts manufacture craft simple, the heat transfer efficiency height, the reliable flag formula of safe water circulation heating surface, need not the special equipment manufacturing, compact conformation, boiler volume only are equivalent to half of volume of the same type.Suddenly can guarantee the local Natural Circulation that forms of burner hearth after having a power failure, the burner hearth return water temperature is 70 ℃, when pressure 0.7MPa, and temperature gap under the saturation pressure, vaporization time prolongs when making unexpected powers failure, moves for operation and has created the favourable operating time.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the front view of boiler body;
Fig. 3 is the vertical view of boiler body;
Fig. 4 is the structural representation of boiler flue;
Describe in detail below in conjunction with accompanying drawing:
As shown in the figure, the utility model has a fire grate botton plate 1, places boiler body 2 on fire grate botton plate 1, and building between stone or metal plate for standing a stove on as a precaution against fire chassis 1 and boiler body 2 has furnace wall 3, and boiler body and burner hearth are surrounded burner hearth and back-end surfaces two parts.The upper left quarter of boiler body 2 is provided with drum 4, dividing plate is set in drum 4 and the carbonated drink balance pipe is arranged.Arch before and after in burner hearth, being furnished with, before and after arch tube 5,7,8,14 respectively with the next part case 15 at upper drum 4 and front and back arch place, in horizontal collection case 17 link to each other, two side water wall tubes 16 link to each other with upper collecting chamber 9, next part case 15, both sides upper collecting chamber 9, roof tube 6 link to each other with drum 4, and back upper collecting chamber 10 is connected with upper collecting chamber 9; Tube connector 20 supports drum 4 and couples together with next part case 15, horizontal collection case 19 before next part case 15 is connected with by tube connector 18; And form a tower structure with the flag formula heating surface 11 that the rear portion is provided with.
The flag formula heating surface 11 at rear portion is formed by two groups, and first group is single flag heating surface that in-line arrangement is arranged transversal flow, and second group of the middle part is the flag formula heating surface that double stagger arrangement is arranged.Upper end at flag formula heating surface 11 connects water outlet collection case 12 by tube connector 13.Each flag formula heating surface respectively accounts for half, be symmetrically arranged, and this group flag formula face with about go up the next part case and connect and form closed circuit.
Before left and right two next part casees 15, locate to be provided with dividing plate between several the 22nd, 23 water screen tubes; Several the 46th water screen tube places are provided with dividing plate before the left and right upper collecting chamber, and by the dividing plate that is provided with in the drum, make rear arch the 43rd locate to form the decline loop and by front and back arch tube rear arched tube with in horizontal collection case, the horizontal collection case in middle back links to each other and supports an also cooling effect of rear arch.
The flue structure of boiler is made up of furnace outlet 21, first convection pass 22, dust chamber 23 and second convection pass 24; Flue gas enters convection pass by furnace outlet and is moved into from top to bottom behind the reversal chamber again that 90 ° of turnings move upward.In the turning process, big particle relies on action of centrifugal force to drop in the expansion chamber, because that the height of expansion chamber changes the second convection pass height over to apart from flue gas is bigger, falls into expansion chamber to making a large amount of dusts break away from flue gases.
The anterior water inlet of drum, the following current of afterbody flag formula heating surface water outlet is arranged, the heat transfer efficiency height.
