Abstract

The utility model relates to a high-temperature steam boiler.

Description

High-temperature steam boiler

Technical field

The utility model relates to a kind of high-temperature steam boiler.

Background technology

At present, D level boiler has two kinds, and one is 118 ℃ of 0.09 MPa, vapor (steam) temperatures, and one is 108 ℃ of 0.04 MPa, vapor (steam) temperatures.In the stove outer covering 2 of these two kinds of boilers, have flue 1, the furnace gall head 3 of flue top connects flue 4, and flue epimere passes stove outer covering end socket 5, flue epimere overcoat vapour jacket 7, and upper termination steam outlet pipe 8, bursting tube 10, flue 9 runs in flue top; In flue, be furnished with horizontal water tube 12, there is grate pipe 14 below.On stove outer covering, there are water-level gauge 11, upper furnace door 13, running water inlet pipe 15, air door 16, blow-off pipe 17 and inspection opening 18, blower fan mouth 19.The boiler of this structure, has a large amount of waste heats to run away from flue, has wasted a large amount of heat energy, causes vapor (steam) temperature low, and operating rate is slow, energy heterodyne.

Need existing boiler to transform for this reason; advantage is designed double-flue boiler; but be horizontal; as a < < horizontal type double-flue industrial coal powder boiler > > (Chinese Patent Application No. 20111004309), the front and rear in shell arranges respectively a front end-plate and an end plate; Middle part at front end-plate is axially equipped with two precombustion chambers side by side, and the port of export of two precombustion chambers is communicated with respectively two one end of horizontal horizontal flue in shell side by side, and the other end of two flues is communicated with end plate respectively; Between the front end of shell and front end-plate, form a front smoke box, between the rear end of shell and end plate, by a baffle for separating, become upper and lower two parts, a rear smoke box is formed at bottom, and a fume collecting chamber is formed at top; In rear smoke box, be vertically installed with a (water) wall circuit, the top of fume collecting chamber is communicated with a chimney; The middle lower portion of two flues is axially provided with one group of two return smoke pipe that is communicated with forward and backward smoke-box, and the upper axial of two flues is provided with one group of three backhaul smoke pipe that are communicated with front smoke chamber and fume collecting chamber.< < Double-liner normal pressure hot water heating stove > > (China Patent No. 90206423.1), in the inner side of flue 5, set up again an inner furnace, the top of inner furnace is equipped with to eliminate smoke and is dried, and between flue and inner furnace, by horizontal water tube, is communicated with.

It is vertical that only to have China Patent No. be 201110259966 vertical type inner container-free double grate boiler.

Summary of the invention

The purpose of this utility model is for above-mentioned present situation, and aiming to provide a kind of heat energy can make full use of, and vapor (steam) temperature is high, the high-temperature steam boiler that operating rate is fast, efficiency is high.

The implementation of the utility model object is, high-temperature steam boiler, has flue in stove outer covering, be furnished with horizontal water tube in flue, and there is grate pipe below; On stove outer covering, there are water-level gauge, upper furnace door, running water inlet pipe, air door, blow-off pipe and inspection opening, blower fan mouth; On the furnace gall head of flue top, have the flue communicating with flue, flue epimere passes stove outer covering end socket, upper termination bursting tube, and flue runs in flue top; In flue, be furnished with Multi-way U-shaped pipe, the outlet of U-shaped pipe connects steam outlet pipe.

The furnace gall head of the utility model flue top connects the flue communicating with flue, is furnished with Multi-way U-shaped pipe in flue, and the outlet of U-shaped pipe connects steam outlet pipe.The great quantities of spare heat producing in flue enters flue by interface channel, in flue, through the heat absorption of Multi-way U-shaped pipe, waste heat is fully utilized, and has greatly improved the efficiency of boiler.Boiler produces after steam, and steam enters Multi-way U-shaped pipe, utilizes the waste heat in flue to heat steam again.

Accompanying drawing explanation

Fig. 1 is the utility model structural representation,

Fig. 2 is stove outer covering structure top view.

The specific embodiment

The utility model is described in detail in detail with reference to the accompanying drawings.

With reference to Fig. 1,2, in stove outer covering 2 of the present utility model, there is flue 1, the furnace gall head 3 of flue top connects flue 4, and flue epimere is through stove outer covering end socket 5, upper termination bursting tube 10.Flue 9 runs in flue top; In flue, be furnished with Multi-way U-shaped pipe, the outlet of U-shaped pipe connects steam outlet pipe 8; In flue, be furnished with horizontal water tube 12, there is grate pipe 14 below.On stove outer covering, there are water-level gauge 11, upper furnace door 13, running water inlet pipe 15, air door 16, blow-off pipe 17 and inspection opening 18, blower fan mouth 19.

Through the flue epimere overcoat vapour jacket 7 of stove outer covering end socket 5, can avoid heat outwards to distribute.

The furnace gall head of the utility model flue 1 top connects flue 4, is furnished with Multi-way U-shaped pipe 6 in flue, and the outlet of U-shaped pipe connects steam outlet pipe 8.Flue 4 has been equivalent to barrier in the utility model another upper furnace.The great quantities of spare heat producing in flue enters flue by interface channel, in flue, through the heat absorption of Multi-way U-shaped pipe, waste heat is fully utilized, and has greatly improved the efficiency of boiler.Boiler produces after steam, and steam enters Multi-way U-shaped pipe, utilizes the waste heat in flue to heat steam again, makes the low temperature of 118 ℃ of former boiler become the high-temperature steam of 400 ℃ of vapor (steam) temperatures, from steam outlet pipe 8, exports, and the power of boiler has been improved more than 3 times.

The utility model both can supply 0.09 MPa, the high-temperature steam of 400 ℃, again can supplying hot water.
