Abstract

The utility model relates to a steam generator, which is suitable for steam provision for industries and the life and can also be used for providing large-capacity hot water. The steam generator forms a vertical cylinder casing. A lower smoke collection chamber is arranged in a bottom part in the casing. An upper smoke collection chamber is arranged in a top part in the casing. A water tank is arranged in a middle part in the casing. A combustion chamber is arranged in the upper part of the water tank. Water pipes are distributed in the combustion chamber. The water pipes are led to the water tank for circulation. Fire pipes are evenly distributed in a lower part in the water tank. Smoke pipes are arranged around the fire pipes. The utility model has the advantages of compact structure, small ground occupation, large heat-exchange area, great water capacity, safety, high efficiency, energy-saving, and continuous air generation.

Description

Steam generator

The utility model relates to a kind of steam generator, particularly a kind of fuel oil or combustion gas steam generator, be applicable to industrial provide steam or the life with steam is provided, also can be used to provide big capacity hot water.

Existing small-sized steam generator has electrical heating or coal heating steam generator, for coal heating steam generator, exists the thermal efficiency low, can not evenly give vent to anger labour intensity height, problem, particularly problem of environmental pollution such as automaticity is low continuously.And for the electrical heating steam generator, its power consumption is big, easily burns ring electricity ring electrothermal tube etc.

The purpose of this utility model provides a kind of steam generator, adopts the multistage heating arrangement of countercurrent heat exchange, makes full use of burner exhaust heat, reaches thermal efficiency height, big, the quick continuous purpose of aerogenesis of water capacity.

Steam generator is vertical cylinder shell, be provided with water inlet in lower part of frame, the top is provided with gas outlet, chimney, Pressure gauge and safety valve, bottom in the housing is a lower smoke chamber, top in the housing is a upper smoke collecting chamber, middle part in the housing is a water tank, top in the water tank is provided with a combustion chamber, is furnished with water pipe in the combustion chamber, and water pipe leads to the water tank circulation, bottom in the water tank is evenly equipped with fire tube, the periphery of fire tube is a smoke pipe, and the combustion chamber is led in the fire tube upper end, and lower smoke chamber is led in the lower end, upper smoke collecting chamber is led in the upper end of smoke pipe, and lower smoke chamber is led in the lower end.Outside housing, be provided with the liquid level observation tube, the observation tube joining water box.

The utility model adopts the multistage heating arrangement of countercurrent heat exchange, its compact conformation, and floor space is little, and heat exchange area is big, and water capacity is big, has safe, efficient, energy-conservation, the characteristics of aerogenesis continuously.
