Abstract

The utility model provides a vertical double-row heat exchanging boiler with a novel structure, and scale deposit can not accumulate in the utility model. A boiler body structure is mainly composed of a vertical compound water jacket 23 on the circumference of the boiler, a built-in external linking type water pipe fire grate 5, vertical fire pipes 7 arranged in parallel in the boiler and an upper smoke box 11. The utility model effectively overcomes the defects that all water pipe fire grates are provided with non-radial holes and D-grade boilers can not be manufactured existing in the prior art. The utility model manufactures an E-grade hot water boiler in a combining way according to the design requirements of D-grade boilers. The utility model has the advantages of compact structure, small volume, good coal type adaptability, high heat exchanging efficiency, safe operation, economy, practicability, convenient inspection and maintenance, no noise, no pollution and no scale deposit.

Description

Vertical double-row of heat-exchange boiler

The utility model relates to a kind of novel structure, not incrusted vertical double heat exchange boiler.

Prior art, the water pipe fire grate is separated upper and lower burner hearth, and cast iron grate is arranged at the bottom of lower hearth, and water pipe furnace grate all has non-radial hole.So it can not make D level boiler, thereby has limited its manufacturing scope of application.

The purpose of this utility model is to overcome the defective of above-mentioned existence, proposes a kind of novel structure and not incrusted vertical double heat exchange boiler, also claims vertical double composite boiler.

Technical solution of the present utility model, structure are shown in the accompanying drawing.Vertical compound water jacket 23 is located at the stove periphery, the built-in external coupling type water pipe furnace grate 5 of burner hearth is arranged in the middle of the burner hearth, separate upper and lower burner hearth, the heat exchanger tube 8 that block form vertical fire tube 7 is provided in a side of the top of upper furnace in the stove be located at furnace internal-lining 20 around, upper smoke box 11 is provided in a side of the top of vertical fire tube 7, built-in external coupling type water pipe furnace grate header tube 30 connects two of the built-in external coupling type water pipe furnace grate 5 of burner hearth, two ends of header tube 30 connect body of heater outer lower collecting box union elbow 37 and upper header union elbow 38 respectively, and lower collecting box tedge 31 joins with the chuck of burner hearth.

Accompanying drawing 1 is the utility model side cross-sectional view.

Accompanying drawing 2 is the utility model principal section structural representations.

Accompanying drawing 3 is burner hearth flat cutting face structural representations.

1 is U-shaped pin circle among the figure, the 2nd, and lower furnace door, the 3rd, upper furnace door, the 4th, lower hearth, the 5th, built-in external coupling type water pipe furnace grate, the 6th, upper furnace, the 7th, block form vertical fire tube in the stove, the 8th, heat exchanger tube, the 9th, heat transfer Liu, the 10th, flat envelope formula tube sheet, the 11st, upper smoke box, the 12nd, furnace roof end socket, the 13rd, furnace top pressure table, the 14th, titting water outlet, the 15th, chimney, the 16th, safety valve joint, the 17th, storage steam bubble, the 18th, end socket in the stove, the 19th, shoot door on the stove, the 20th, furnace internal-lining, the 21st, stove outer covering, the 22nd, burner hearth case, the 23rd, compound water jacket, the 24th, water jacket water inlet pipe mouth, the 25th, shoot door under the stove, the 26th, fixing grate, the 27th, heat transfer agent import, the 28th, stove footwork orchid, the 29th, body of heater spats circle, the 30th, built-in external coupling type water pipe furnace grate header tube, the 31st, lower collecting box tedge, the 32nd, normal water bit line, the 33rd, liquid level meter joint, the 34th, the lower hearth inner casing, the 35th, decontrol water swivel, the 36th, the grate backing ring, the 37th, the lower collecting box union elbow, the 38th, upper header union elbow, the 39th, body of heater header hole, the 40th, heat transfer agent pressure tapping.

Below in conjunction with accompanying drawing scheme of the present utility model is further described: the coal charge of stove when operation is to add upper furnace 6 by upper furnace door 3, through upper furnace half-dried saute partly be oxidized to the semicoke shape after, from the gap of built-in external coupling type water pipe furnace grate 5, fall into lower hearth 4 and carry out second-time burning, rise to again in the upper smoke box 11 after producing a large amount of high temperature carbon dioxide air-flows simultaneously block form vertical fire tube 7 absorbing a large amount of heat energy in the stove, discharge from chimney 15 at last, because above-mentioned high temperature carbon dioxide air-flow flow process distributes rationally, each heating surface fully is heated in the stove so can make, and makes sealing and fixing constantly carry out continuous condensing heat-exchange reaction with the water that is entered by water jacket water inlet pipe mouth 24 in the compound water jacket 23 at constantly the be heated surface area that makes heat exchanger tube 8 and flue 20 that heats up of furnace heat transfer agent 9.Because the general structure of vertical double heat exchange boiler (also claiming vertical double composite boiler) is by the relevant rules requirement design of D level steam boiler, and emphasis overcomes the existing in prior technology shortcoming, especially neither one non-radial hole in whole furnace binding, stove internal heating surface (except that welded tube) is butt welding entirely, need not any subsidiary engine in when operation, not power consumption, scaling not, and integrate the double heat exchange boiler of novel vertical of boiler, economizer, deduster, ion-exchanger.

This stove noiselessness, no smoke contamination can be resident's heat supply of hotel, office, army, school, hospital and the residential quarters of vast industrial and mining enterprises (comprising numerous township enterprises) and small and medium-sized cities, various places, supplies water.

Claims
