Fire Tube Boiler

Product Description

The Fangkuai fire tube boiler series is a typical horizontal full-humid back center back-burning three-pass structure, the fuel is fully stretched in the large furnace volume, and the micro positive pressure is burned; and the waste heat of the flue gas is reabsorbed through advanced condensation technology, fully using the sensible heat and latent heat in the flue gas, the heat is put into the boiler again, which further improves the boiler efficiency. The exhaust gas temperature is only about 50 °C, and the boiler thermal efficiency can reach more than 96%; the steel-aluminum composite finned tube of the condenser The structural composition is more reasonable, the thermal conductivity is better, and the life of the boiler is improved at the same time.

Product Advantages

• High heat transfer efficiency

  The vertical fire tube boiler realizes cascaded utilization of flue gas waste heat and greatly improves efficiency. The spiral finned tube is used for heat exchange, and the heat exchange surface is sufficient.

• Unique flue structure

  The fire tube boiler adopts a reasonable flue structure, and the condensed water is easy to discharge and collect for treatment, reducing the corrosion of the heat exchange surface.

• Good insulation performance

  The fire tube water boiler adopts a new type of heat insulation material, which has good heat preservation performance, light weight and less heat loss.

• Easy to use

  Digital controller, friendly man-machine interface, multiple language options, can realize man-machine dialogue, and control the operating status of the boiler.

Technical Features

• Corrugated Furnace

  The corrugated furnace is independently developed, designed, and manufactured by Fangkuai, and it is more closely integrated with the boiler. Compared with the conventional furnace, the corrugated design greatly increases the heating area of the furnace and makes the heating more uniform. At the same time, it prevents the furnace from breaking due to free expansion due to high-temperature combustion.

• waste heat integration

  On the basis of the traditional fuel gas hot water boiler, the fire tube boiler has added an integrated solution for waste heat utilization. A condensation recovery device is installed at the end of the flue. After the high temperature passes through, the latent heat is released, and the exhaust gas temperature can be reduced to 95 ℃, The thermal efficiency is as high as 96%, and the cost performance of enterprise investment is very high.
