Smokeless warm bath boiler

Abstract

The invention relates to a warm bath boiler, in particular to a smokeless warm bath boiler, and belongs to the technical field of designing and manufacturing of normal-pressure hot water boilers.The warm bath boiler comprises a boiler hearth, a foot ring hearth and an air inlet pipe.The air inlet pipe comprises a primary air inlet pipe body and a secondary air inlet pipe body, an air inlet of the primary air inlet pipe body is located in the side face of the boiler foot ring hearth, an air inlet of the secondary air inlet pipe body is located in the middle or the upper portion of the side face of the boiler hearth, and the primary air inlet pipe body and the secondary air inlet pipe body are connected with a combustion fan.According to the smokeless warm bath boiler, the dust content in discharged smoke is small, environmental pollution is small, and the heat efficiency of the boiler can be remarkably improved.

Description

technical field [0001] The invention relates to a heating bath boiler, in particular to a smokeless heating bath boiler, which belongs to the technical field of design and manufacture of atmospheric pressure hot water boilers. Background technique [0002] At present, most of the atmospheric pressure hot water boilers sold on the market use manual control of coal combustion, which cannot automatically control coal combustion, the water temperature control is not timely, high energy consumption and time-consuming and laborious. Moreover, after the coal is burned, a large amount of boiler smoke and soot are brought out from the furnace. In the prior art, the smoke and dust are generally removed by using the method of water mist dust removal to prevent the smoke and dust from flowing into the air to pollute the environment. However, this method of dust removal will produce a large amount of waste water with smoke and dust, causing secondary pollution. In addition, the boiler f...

Problems solved by technology

In the prior art, the smoke and dust are generally removed by using the method of water mist dust removal to prevent the smoke and dust from flowing into the air to pollute the environment. However, this method of dust removal will generate a large amount of waste water with smoke and dust, causing secondary pollution

In addition, the boiler foot ring is single-layer, the furnace bridge is cast iron furnace bridge, and there are only a few horizontal fire tubes in the boiler chamber. The thermal efficiency of the boiler is low, the exhaust gas temperature is high, and the coal consumption has caused a great waste of resources.
