Abstract

The utility model relates to a vertical steam water boiler which comprises a boiler body, a fire grate, a combustion chamber, a flue, a heating pipe, etc. A convection steam superheater is arranged in an upper smoke chamber on the upper part of a transverse water pipe set, a steam inlet pipe of the superheater is communicated with a steam outlet pipe for saturated steam of the boiler and the steam outlet pipe is led out from the upper end of the boiler body. The utility model has the functions of supplying hot water, the saturated steam and superheated steam and satisfying various using requirements, and has flexible and convenient selection, alternation and application.

Description

Vertical steam and hot water boiler

The utility model relates to coal-fired vertical steam and hot water boiler.

Its structure of vertical boiler constitutes varied in the prior art, include body of heater, fire grate, the combustion chamber, flue, and the various vertical boilers of heating tube and other servicing unit formation, different mainly variation that its structure constitutes in the combustion chamber, heating tube, flue structure is textural, to improve the thermal efficiency, each have its oneself characteristics, but because this vertical boiler mainly is to be used for civilian water heater drinking water boiler, satisfy the general domestic water vapour of people, all volume is less for one, so vertical steam and hot water boiler of prior art, its structure constitutes not setting and does not have the superheated steam of generation function, along with the development and change of society, demands of applications, this function singleness, can only provide the vertical type water heater boiler of hot water and common saturated vapor, with not in the demand that can satisfy people.

The purpose of this utility model is to improve at the deficiency of existing vertical Steam water-heating boiler, provide a kind of simple in structure, hot water and common saturated vapor not only can be provided, and superheated steam can be provided, and select the vertical easily steam and hot water boiler of applying flexible.

The utility model includes body of heater, fire grate, the combustion chamber, flue, formations such as heating tube, its technical characterictic is, above the burner hearth inner combustion chamber of body of heater, be provided with heating horizontal water tube group, be provided with the convection type steam superheater in the smoke-box between the top of horizontal water tube group and exhaust opening, the boiler saturated vapor steam outlet pipe that draw the steam inlet pipe of superheater and body of heater upper end interlinks, saturated vapor in the boiler enters in the superheater by its steam outlet pipe, further heat by the pipeline of superheater and the high hot smoke convection formula heat exchange in the last smoke-box, make saturated vapor be transformed into superheated steam, make the utility model boiler both can provide hot water and saturated vapor like this, can provide superheated steam again.

Accompanying drawing is the utility model structural representation.

Further specify the utility model below in conjunction with accompanying drawing.

The utility model includes vertical water-jacket typ body of heater 1, fire grate 2, combustion chamber 3, smokejack 5, heating horizontal water tube 4, and be opened in water inlet on the body of heater 1, water outlet, steam drain, fire door, ash discharging hole constitutes, on the upper box body 11 of body of heater 1, offer smoke exhaust pipe 5, bottom in body of heater 1 is provided with fire grate 2 and combustion chamber 3, heating horizontal water tube group 4 is set above body of heater 1 burner hearth inner combustion chamber 3, it is characterized in that, on 50 of the top of horizontal water tube group 4 and outlet flues, be provided with convection type heating steam superheater 6 in the smoke-box 30, the steam outlet tube 12 that the steam inlet pipe 61 and the body of heater 1 upper end casing 11 of superheater 6 heat exchanger tubes are drawn interlinks, saturated vapor in the boiler enters in the superheater 6 by its steam outlet pipe 12, further heat by the pipeline of superheater 6 and the high hot smoke convection formula heat exchange in the last smoke-box 30, make saturated vapor be transformed into superheated steam.

The utility model is provided with on saturated vapor steam outlet pipe 12 pipelines of body of heater 1 outside and is connected with steam-water separator 8, is provided with in the lower end of steam outlet tube 12 and is connected with gas-distributing cylinder 9.

The steam inlet pipe 61 of the utility model superheater 6 is connected with the saturated vapor steam outlet pipe 12 of steam outlet pipe 62 with body of heater 1 outside, steam pipe 12 between the interface of the steam inlet pipe 61 of superheater 6 and steam outlet pipe 62 and steam pipe 12 ' be provided with valve 14, in other words conj.or perhaps the steam inlet pipe 61 of superheater 6 and 62 of steam outlet pipes be connected with connecting leg 12 ', this connecting leg 12 ' on be provided with valve 14.The utility model is in the time only need providing saturated vapor to use with it, with be communicated with the steam inlet pipe 61 of superheater 6 and the connecting leg 12 of steam outlet pipe 62 ' on valve 14 open, saturated vapor does not then enter superheater 6 and further heats, and directly is sent (to gas-distributing cylinder 9) for using; In the time only need providing superheated steam to use, special be communicated with the steam inlet pipe 61 of superheater 6 and the connecting leg 12 of steam outlet pipe 62 ' on valve 14 close, saturated vapor then enters in the superheater 6, further is heated as superheated steam, discharges (delivering to gas-distributing cylinder 9) for using from steam outlet pipe 62 then.

The utility model on the steam inlet pipe 61 of superheater 6 and steam outlet pipe 62, also can be provided with the arm 61 of valve 63,64 and band valve ', 62 '.The utility model is not when needing to provide superheated steam to use, can saturated vapor pipeline 12 disconnections of superheater 6 with body of heater 1 thoroughly be disconnected by valve 63,64, and with the steam inlet pipe 61 of superheater 6 and steam outlet pipe 62 by its arm 61 ', 62 ' join with water inlet pipe and drainpipe, making superheater 6 become the heat exchange heating tube uses, be used to provide warm water hot water, for use such as bathing, perhaps by arm 61 ', 62 ' be communicated with body of heater 1, heating tube as body of heater is used, and makes it have multiple application function.

The utility model is simple in structure, hot water and common saturated vapor not only can be provided, and superheated steam can be provided, has multiple application function, one stove can satisfy multiple instructions for use, and selects the conversion applying flexible convenient, and being particularly suitable for needs to use the small enterprise unit of superheated steam to use.
