Description

Technical Field

[0001] The utility model relates to a horizontal hot water boiler and belongs to the technical field of hot water boilers. Background Art

[0002] As a heat energy conversion device, a horizontal boiler is mainly composed of a furnace, a burner, a heat transfer tube, a water circulation system and a control system. Its working principle can be broken down into the following steps: the burner introduces fuel, mixes it with air, and forms a combustible mixed gas. The combustible mixed gas enters the furnace and is ignited to produce high-temperature combustion gas. The high-temperature combustion gas passes through the heat transfer tube and transfers heat energy to the outside world. During the process, the circulating water system absorbs the heat energy and sends it to other equipment.

[0003] During the use of existing horizontal hot water boilers, the hot water heated inside is prone to condensation of scale, which then causes scale to remain in the furnace and the inner wall of the boiler, thereby reducing the heat conduction effect. The boiler is difficult to clean quickly in a sealed state, which tends to gradually reduce the boiler's energy efficiency. When the boiler discharges flue gas, it is easy to carry harmful substances and heat into the air, which not only reduces the environmental friendliness of the boiler, but also easily causes a large amount of heat loss, making it difficult to efficiently utilize the heat generated by the boiler.
