Description

The vertical normal-pressure boiler of family expenses

The utility model belongs to heating stove, is the vertical normal-pressure boilers of a kind of family expenses.

At present, the vertical normal-pressure boiler that China generally uses in town and country, its architectural feature is: form annular water storage space between boiler urceolus and the inner bag, we claim annular water chamber, and the inner bag bottom is the combustion chamber, is provided with fire tube in the inner bag, are communicated with combustion chamber and chimney.After the fuel combustion, the water by in the fire tube wall heating annular water chamber makes it the convection current heat supply.The disadvantage of this fire tube boiler is that heat exchanger effectiveness is low.

The purpose of this utility model is the deficiency at prior art, and a kind of thermal efficiency height is provided, and can clear up the vertical normal-pressure boiler of family expenses of boiler smoke incrustation easily.

The utility model is realized by following technical scheme.It comprises urceolus, the inner bag of common vertical normal-pressure boiler and the annular water chamber that forms between them, and the fire grate, combustion chamber and the inner bag that are arranged in the inner bag bottom are communicated with the vertical fire tube of combustion chamber and chimney.This common fire tube boiler is improved, be provided with cross inner bag and be communicated with annular water chamber to overflow pipe, this horizontal water pipe is the top by the combustion chamber, upwards arranges the 2-8 layer along boiler height, every layer has 2 at least.It above horizontal water pipe the straight-through chimney of fire tube.Offer cleaning door at the boiler middle part.Above the upper boiler fire tube, also be provided with cleaning door.The cleaning door at boiler middle part is by regulating flap gap size, double as secondary air mouth.The top of upper boiler fire tube also is provided with the water pipe that is communicated with annular water chamber.The outside at the boiler middle part connects potable water tank, and a sidewall of potable water tank directly contacts with inside of boiler.

Compared with the prior art the utility model has reasonably been arranged morely to overflow pipe owing to cross inside of boiler above the combustion chamber, has increased heating surface area widely; Because upper boiler fire tube top also is provided with overflow pipe, has absorbed the fire tube waste heat effectively.Therefore, the utility model has been realized higher heat exchanger effectiveness.Simultaneously, two cleaning doors are set, have guaranteed to clear up flue easily,, thereby realized the thermal efficiency steady in a long-term the black dirt in overflow pipe, the fire tube.Because the cleaning door double as secondary air mouth at boiler middle part can be opened when needing and cover under the air effect of secondary air, makes fuel completing combustion, has improved the thermal efficiency, has reduced fume emission and has put.Because the utility model thermal efficiency height, can set up potable water tank as required, more convenient use.

Below in conjunction with accompanying drawing, the utility model is further described by embodiment.

Fig. 1 is a front view of the present utility model;

Fig. 2 is the side cutaway view of Fig. 1.

As shown in Figure 1 and Figure 2, the vertical normal-pressure boiler of a kind of family expenses, its structure comprises: boiler urceolus 1, inner bag 2 and the annular water chamber 3 that forms between them are positioned at fire grate 4, combustion chamber 5, charge door 6, the ash hole 7 of inner bag bottom, and the fire tube in the inner bag 8, the chimney 9 that is communicated with inner bag.5 the top in the combustion chamber, be provided with cross inner bag and is communicated with annular water chamber to overflow pipe 10, totally 8 layers in this water pipe is upwards arranged along boiler height, every layer of 4-5 root layout.Above horizontal water pipe 10 fire tube 8 of straight-through chimney 9, totally 3 of this fire tubes, triangle distributes.Tube side is offered cleaning door 12 to offering cleaning door 11 above the upper boiler fire tube downstream at the middle part of boiler.The cleaning door 11 double as secondary air mouths at boiler middle part can be controlled the flap gap size as required, regulate air capacity, make sufficient combustion.In order to absorb waste heat, above the upper boiler fire tube, also be provided be communicated with annular water chamber to overflow pipe 13.In order to drink water conveniently, can be at potable water tank 14 of the outside at boiler middle part welding, its sidewall directly contacts with inside of boiler 2.Potable water tank is provided with exhaust outlet 17, filler 18, delivery port 19, sewage draining exit 20.Be provided with two delivery ports 16 at the top of boiler, the bottom is provided with two water return outlets 15, and boiler also is provided with safety valve 21.

To the quantity that overflow pipe is provided with, select according to the size of boiler heat supplying amount, be generally the 2-8 layer, every layer has 2 at least.
