Fire tube boilers, ZOZEN fire tube boilers are widely used in various industries

1. Fire tube boilers definition

Fire tube boilers is a type of boiler in which hot gases pass from a fire through one or (many) more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam. The fire tube boilers can be divided into two types: the two pass boiler and the three pass boiler.

2. Fire tube boilers advantages

--compact structure, small area coverage, low investment

--skid-mounted delivery, save installation costs and time

--low feed water requirement, low operation and maintenance costs

4. ZOZEN fire tube boilers Application

1) South Africa Building Material Company Pholaco

Equipment: WNS4-1.25-Y

Introduction: Steam boilers play an significant role in the processes of plasterboard drying, concrete component maintenance, decorate materials drying and the production of moulded bricks. Pholaco is a company specialized in the production of building materials in South Africa. This time, Pholaco planned to order several fire tube boilers for ZOZEN, which used heavy oil as the fuel. This series of fire tube boilers adopt a large corrugated furnace to ensure the complete fuel combustion. In addition, an advanced burner is also equipped to realize ultra low NOx emissions. With features of easy operation and short installation period, the boiler can be put into operation in a short time.

2) New Hope Indonesia

Equipment: DZL-1.25-AII

Introduction: Located in Central Java, Indonesia, PT. New Hope Indonesia introduced ZOZEN high-quality and highly-efficient DZL series coal-fired steam boiler, which provided reliable heat source guarantee for feed production. DZL series boilers adopt horizontal single-drum structure and a chain grate and take the lead in adopting arched tube plates and thread smoke tubes to increase heat conduction. The heat transfer coefficient of thread smoke tubes is 1.8 times higher than normal tubes. This series of fire tube boilers have the advantages of high efficiency and low emission, the thermal efficiency is increased to more than 82%, and the NOx emission is less than 100mg/Nm³.

With a wide duel adaptability including various kinds of oil, gas and solid fuel, ZOZEN fire tube boilers are widely used in chemical, pharmaceutical, paper, textile, food, electronics, automobile manufacturing and other industries.
