Hot water boiler with double combustion chambers

Abstract

A hot water boiler with double combustion chambers comprises a boiler body. A water heating chamber, the first combustion chamber, the second combustion chamber, a smoke collection chamber, an ash chamber and a smoke filter box are arranged in the boiler body. The water heating chamber is arranged at the upper left end inside the boiler body. The first combustion chamber is arranged at the lower end of the water heating chamber. The smoke collection chamber is arranged at the right ends of the water heating chamber and the first combustion chamber. The ash chamber is arranged at the lower ends of the first combustion chamber and the smoke collection chamber. The second combustion chamber is arranged in the middle of the interior of the water heating chamber. A smoke box is arranged inside the smoke collection chamber. The interior of the smoke box is composed of an upper cavity and a lower cavity. The upper right end of the first combustion chamber is connected with the lower cavity through a first smoke conveying pipe. The lower right end of the second combustion chamber is connected with the upper cavity through a second smoke conveying pipe. The upper cavity is connected with the smoke filter box through a heat exchange smoke pipe. The lower cavity is connected with the smoke filter box through a heat exchange smoke pipe. The hot water boiler is provided with the two combustion chambers, the heat exchange area is enlarged, the heat efficiency is improved, and the water heating speed is increased.

Description

technical field [0001] The invention relates to the field of boiler equipment, in particular to a hot water boiler with double combustion chambers. Background technique [0002] For most rural areas, household heating equipment is an indispensable equipment in people's winter life. Except for residential areas with central heating conditions in cities, most rural areas still use traditional household boilers for heating. [0003] However, most of the existing household boilers are coal-fired boilers, which generally have the following deficiencies: first, the existing household coal-fired boilers are not fully burned, which is likely to cause waste of resources, and the smoke is directly discharged, which pollutes the environment; Second, most of the existing domestic coal-fired boilers have only one combustion chamber, and the combustion speed is relatively slow, resulting in low hot water efficiency and unable to quickly realize heating; third, the existing domestic coal-f...

Problems solved by technology

[0003] However, most of the existing household boilers are coal-fired boilers, which generally have the following deficiencies: First, the existing household coal-fired boilers are not fully combusted, which is likely to cause resource waste, and the flue gas is directly discharged, causing great environmental pollution; second, most of the existing domestic coal-fired boilers only have one combustion chamber, and the combustion speed is relatively slow, resulting in low hot water efficiency and unable to quickly realize heating ; Third, the existing domestic coal-fired boilers do not fully utilize the waste heat of the flue gas, the heat utilization is relatively unsatisfactory, and the insulation effect of the furnace body is poor; fourth, the existing domestic coal-fired boilers generally have a relatively small volume. Small, insufficient heat supply, and it is inconvenient to clean up ash. Coal burning is also easy to pollute indoor air, cause gas poisoning, and it is inconvenient to use, which has brought a lot of trouble to the residents; fifth, the use of electric boilers is restricted by the market. The power supply is affected, and the power consumption is large, and the use cost is high
