Overview
A steam boiler is an industrial boiler that heats water to a certain parameter and produces high-temperature steam. The principle of a boiler is that water is heated into steam inside the drum, and the fire releases heat inside the furnace. Boilers belong to special equipment. The design, processing, manufacturing, installation, and use of boilers must be supervised by the technical supervision department. Users must obtain a boiler usage certificate before they can use the boiler. The device can be divided into three categories based on fuel (electricity, oil, gas). According to the structure, it can be divided into vertical and horizontal types. Small and medium-sized boilers are mostly single or double loop vertical structures, while large boilers are mostly triple loop horizontal structures.
Product Details
working principle
Heating equipment (burner) releases heat, and the water-cooled wall absorbs heat through radiation heat transfer, boiling, and vaporization. A large amount of steam is generated and enters the steam drum, where it undergoes steam water separation (except for once through furnaces). Saturated steam enters the superheater. By radiation and convection, continue to absorb the heat from the furnace top, horizontal flue, and tail flue gas to achieve the required level of superheated steam. Required operating temperature. Power generation boilers are usually equipped with reheaters, which heat steam through high-pressure cylinders. The reheater steam enters the medium and low pressure cylinder to continue generating electricity.

steam boilerIt can be divided into electric steam, oil fired boilers, gas boilers, etc. According to its structure, it can be divided into vertical boilers and horizontal boilers. Small boilers are mostly single or double loop vertical structures, while large boilers are mostly triple loop horizontal structures.
Vertical double return structure
The vertical oil and gas boiler adopts a burner shutdown method, a bidirectional structure, and the fuel is fully burned. The boiler is stabilized first during operation; Insert a diffuser into the smoke pipe to reduce exhaust gas velocity, increase heat transfer, improve boiler thermal efficiency, and reduce user usage costs.
Horizontal triple structure
A horizontal boiler is a three-way downstream smoke tube structure with a fully wet back and shell. The flame burns under slight positive pressure in a large combustion chamber, spreading, with low combustion heat load and high combustion thermal efficiency. Effectively reducing exhaust gas temperature, saving energy and reducing consumption, and using it economically. The structure of corrugated furnace liner and threaded smoke tube not only improves the heat absorption strength of the boiler, but also meets the needs of thermal expansion of the heat exchange surface. Scientifically reasonable and durable.

A horizontal steam furnace is a three-way downstream pyrotechnic tube structure with a fully wet back and shell. The flame burns under slight positive pressure in a large combustion chamber, spreading, with low combustion heat load and high combustion thermal efficiency. Effectively reducing exhaust gas temperature, saving energy and reducing consumption, and using it economically.
