Abstract

The utility model discloses a coal non-smoke heat-pipe boiler. The outer parts of the boiler comprise various nozzles and level-meter, etc. The inner parts of the boiler comprise an ash-collecting chamber, a firebox, a hearth and a body water-jacket, etc. The utility model is characterized in that heat pipes are arranged in layers around the firebox, and one end of the heat pipe is arranged in the firebox and the other end is penetrated into the body water jacket; a plurality of top and down crossly arranged boiling pipes are arranged between the body water jackets and are penetrated through the hearth; a boiling bag is arranged above the hearth to communicate with the water jackets of two sides. The utility model has the advantages that the structure is simple and the operation is easy; the occupied space is small and the utility model is suitable for various coals, etc. and especially the utility model can quickly raise the temperature and the burning is completely without smoke and dust, and the heating efficiency can reach 85 percent; the coal-saving effect is distinct and after the checking by the heat-engineering and environment-protecting departments, all the indexes of the utility model are prior to that of the similar products. The utility model relates to an atmosphere pressure and pressure-bearing vertical boiler, the utility model is suitable for the drinking-water supply, life-water supply, heating and industrial-steam supply, etc. of departments, schools, armies, factories, etc. enterprises and their residential buildings.

Description

The coal-burning smoke-less heat pipe boiler

Technical field: the utility model relates to a kind of coal-fired heat pipe boiler.

Background technology: up to the present, Chinese patent discloses some boiler technology schemes that relate to hot pipe technique, CN2441079 disclosed " coal-fired heat pipe boiler " is an example wherein, this patent is made up of several portions such as destructive distillation chamber, combustion chamber, burning chamber, cinder chamber, heat-exchanging chambers, and wherein heat pipe is laid on the dividing plate between burning chamber and the heat-exchanging chamber.This boiler obvious defects as the application of hot pipe technique, belongs on the dividing plate indirectly the water heating because it is located at except that the structure complexity, so it also has heat pipe usefulness and problem such as brings into play lowly.

The utility model content:

Task of the present utility model provides a kind of coal-burning smoke-less heat pipe boiler, and it is not only simple in structure, and can make heat pipe give full play to usefulness, and has thermal efficiency height, advantages such as smokeless and dust free.

Technical solution of the present utility model is: a kind of coal-burning smoke-less heat pipe boiler, comprise combustion chamber and furnace water jacket, and it is characterized in that: be provided with heat pipe around in the combustion chamber, an end of heat pipe is positioned at the combustion chamber, and the other end is deep in the furnace water jacket; Between furnace water jacket, be provided with several boiling water tubes and pass burner hearth; Being provided with the boiling water bag in upper furnace is connected with the both sides water jacket.

The said heat pipe in front can be gone up lower leaf on every side and lay in the combustion chamber; Said boiling water tube divides wrong arrangement of interlayer to lay in burner hearth.

Compared with prior art, advantage of the present utility model is:

(1) because layering is laid in combustion chamber heat pipe on every side, and an end is heated by high temperature in the combustion chamber, and the other end directly inserts in the furnace water jacket water, and this direct mode of heating can make the usefulness of heat pipe be given full play to, therefore can effectively improve the thermal efficiency of boiler.

(2) owing to divide the wrong boiling water tube that is laid in the burner hearth of arranging of interlayer directly to be roasted by flame, can make full use of heat energy like this, again can prolong smoke running time in burner hearth, thereby make coal-fired fully burning, therefore the thermal efficiency of boiler not only can be improved, and soot emissions can be reduced.

(3) owing to be provided with the hot water bag, be fully utilized with regard to the high temperature that makes outlet flue like this, therefore, further improved the thermal efficiency of the present utility model in upper furnace.

In addition, the utility model also have simple in structure, deft design, easy and simple to handle, floor space is little, be suitable for advantages such as coal is extensive.Facts have proved the utility model quick heating, sufficient combustion, the thermal efficiency up to 85%, economize on coal significantly.Detect through thermal technology and environmental administration, every index all is better than other similar products, also can't see black smoke when hand-stoked, belongs to the upgraded product that hand burns vertical boiler.

Description of drawings:

Fig. 1 is a structural representation of the present utility model.

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

The specific embodiment:

As shown in the figure, coal-burning smoke-less heat pipe boiler of the present utility model, its body of heater comprises the various mouths of pipe and water level meter etc. outward, comprise dust collection chamber, combustion chamber, burner hearth, furnace water jacket etc. in its body of heater, it is characterized in that: 5 are provided with heat pipe 4 on every side in the combustion chamber, one end of heat pipe 4 is positioned at combustion chamber 5, and the other end is deep in the furnace water jacket 3; Between furnace water jacket 3, be provided with several boiling water tubes 2 and pass burner hearth; Being provided with boiling water bag 1 in upper furnace is connected with the both sides water jacket.Here said heat pipe can be divided into layer around 5 up and down to be laid in the combustion chamber, and the heat pipe number of the number of plies and every layer is laid in decision as required; Said boiling water tube divides wrong arrangement of interlayer to lay in burner hearth, and its number of plies and number are also determined according to concrete needs.

The utility model is normal pressure, pressure-bearing vertical boiler, and enterprises and institutions such as suitable especially office, school, army, factory and dormitory building thereof are as supplying purposes such as drinking-water, domestic water, heating and industrial steam.
