Coal fired water tube steam boiler is one of the types of boilers. It belongs to the category of industrial steam boilers.It is called a water tube boiler because the hot gas surrounds the tube and ultimately heats the water in the tube.Water tube boilers are mainly used in food factories, power plants, central heating, chemical plants, etc.
The overall structure of the water tube steam boiler includes two parts of the boiler body and auxiliary equipment.The main parts of the boiler, furnace, drum, burner, waterwall superheater, economizer, air preheater, frame and furnace wall, constitute the core part of the steam production, which is called the boiler body. The two main components in the boiler body are the furnace and the drum.The boiler auxiliary equipment includes five parts,there are Water supply, Ventilation , coal transportation , ash discharge and dust removal equipment.
How water tube type boilers work?
Maybe many people do not understand much,however,The working principle of water tube boiler is very simple and interesting.It mainly uses the principle of water circulation.Cold water enters from the top of the drum, due to the high density of cold water, the water flows from the down tube to the bottom of the drum.Flue gas flows out of the pipe to release heat, and the water flows inside the pipe to absorb heat and generate steam bubbles. Due to the different density of hot and cold water, hot water will drive the steam along the riser into the upper drum, eventually separating the steam from the hot water and leaving the upper drum, and the hot water then circulates,finally ,the water is heated to a specific parameter (or superheated steam, or saturated steam, or hot water) and sent to the heating equipment.
Our DZL water tube steam boiler has been purchased by a Pakistani customer,When I asked him why do you want to buy a water tube steam boiler ,the client said “ water tube boilers with large capacity, high parameter configuration, high efficiency and cost savings.” And then,I recommended a DZL coal fired steam boiler to him. This is a chain grate boiler that can burn coal or biomass, fuel can be freely chosen by you. Of course, According to the heating surface structure, it belong to water tube boiler. Regardless of combustion efficiency or fuel consumption, DZL horizontal steam boiler is great in every way.At the request of the customer, we transport the goods to Pakistani customers’ companiesby land and nude packaging.
For packaging and shipping issues,Regular packing or nude packing, or upon customers requirement. Transportation by land or by sea, depended on the exporting area.
