Boiler is a kind of special equipment, which involves a lot of knowledge in all aspects of manufacturing and component parts. If you want to understand and master it all, it will take some time and effort; and when we have mastered some characteristics of the boiler, whether it is Buying or operating boilers can avoid many pits.
Today, Zhengzhou Fangkuai Boiler Factory will explain the boiler body to everyone in order to promote the understanding of the boiler.
1. What is the boiler body? Is it included in the overall structure of the boiler?
The boiler body, in simple terms, is the body part of the boiler. Specifically, the structure is mainly composed of the steam drum and its accessories, various heating surfaces, headers and pipes, steam and water system pipes and accessories, combustion equipment, smoke Air ducts, frameworks, etc., as well as furnace walls. There is a boiler body in the overall structure of the boiler, in addition, there are auxiliary equipment; therefore, it can be said that the overall structure of the boiler has two parts, which are the boiler body and auxiliary equipment.
2. What is the role of each part on the boiler body?
The role of various parts on the boiler body, specifically speaking, is mainly as follows:
Evaporation equipment: there are mainly steam drums, headers, downcomers and water-cooled walls, etc. Its specific role is to heat the water to make it saturated steam.
Combustion equipment: there are mainly combustion chambers, burners, and grate, etc. Its role is to provide a place for combustion and good combustion conditions.
Superheater: There are mainly two headers and a serpentine tube, which turns saturated steam into superheated steam. Energy-saving device: the waste heat of flue gas is used to heat the heating surface of the boiler feed water, so that the boiler can run smoothly.
Furnace wall and frame: The furnace wall in the boiler body has a certain shape, generally between the furnace and the flue, with a certain interval. The frame can also be called a steel frame. Its main function is to support the components and equipment in the boiler body.
We, Zhengzhou Fangkuai Boiler Co., Ltd. (Fangkuai), are excited to announce our participation in the Indonesia International Heating Technology Exhibition 2025. We will be showcasing our advanced boiler systems engineered for higher efficiency, lower emissions, and sustainable energy performance.
