As a leading manufacturer of industrial boilers, ZOZEN has a network of sales around the world. Recently, ZOZEN mid-temperature and mid-pressure steam boiler project in Bangladesh was in full swing, fire tube boiler sizing.

fire tube boiler sizing, The condensate water draining performance plays an essential role in the normal operation of gas-fired boiler to prevent the emission of steam when condensate water, air and carbon dioxide are discharged. Intended to realize a better effect of water draining and steam holding, ZOZEN Boiler’s technical team improved the original boiler structure for excellent condensate water draining performance to reduce energy consumption and cut down production cost for the enterprise.

ZOZEN WNS series gas-fired (oil-fired) boilers are wetback fire-tube boilers with a two-pass or three-pass design. It uses threaded smoke tube for heat transfer and manages to achieve a thermal efficiency up to 98%. The economizer is installed at the tail of boiler, giving the boiler a compact size. Meanwhile, sound automatic control system enables unattended operation.

Steam boilers are used to provide steam in bleaching, concentration, drying and other production process of paper industry. Thai Development Industrial Paper Co. , Ltd. is one of large paper mill in Thailand. With the expansion of business and scale, the paper mill had to introduce extra sets of coal-fired steam boilers. ZOZEN supplied 15tph SZL series chain grate steam boilers for the company. This series of steam boiler features wide wide coal applicability and higher combustion efficiency.

fire tube boiler sizing, The furnace of ZOZEN’s SZL series coal-fired boiler adopts a closely arranged water-cooled wall tube structure, which effectively prevents the erosion and radiation of high-temperature flue gas for the furnace. The furnace has large radiation area, small maintenance workload and light overall weight. In order to improve the coal applicability of industrial boilers, ZOZEN Boiler designs adiabatic furnace, water-cooled furnace, adiabatic arch, water-cooled arch, etc., and chooses different furnace structures according to calorific value, volatile content and coking characteristic index of coal provided by customers.

ZOZEN is the first in China to adopt arched tube sheet and threaded smoke tube structure. Threaded smoke pipe is a high-efficiency heat transfer element researched by ZOZEN for many years. After continuous optimization, its heat transfer coefficient is 1.8 times higher than that of ordinary smoke pipe, which increases heat conduction.

Be it a firetube, watertube, hot water, or steam boiler, they are all effective and efficient in their own unique ways. To learn in more detail about the differences between boiler types, visit the section on ZOZEN website, fire tube boiler sizing.
