ZOZEN Improves Condensate Water Draining and Recycling Technology of Gas-fired Boilers

It is known that there is a great deal of condensate water generating in the operation of gas-fired boilers and the draining and recycling of condensate water affects the operation safety and thermal efficiency of the whole boiler system to some extent. ZOZEN Boiler, as an industrial boiler manufacturer established in 1988, has always been improving boiler’s product quality and operation performance with innovative methods. ZOZEN’s high standard for details makes itself grow into the industry leader.

ZOZEN improves condensate water draining performance of WNS series gas-fired boiler in details

The accumulation of condensate water generated by steam’s temperature change in the gas-fired boiler greatly affects the efficiency of heat transfer process and causes the corrosion of flue gas duct due to its acid characteristic. What’s more, once flowing into the boiler proper, it can also shorten boiler’s service life and cause other safety problems, so the condensate water should be drained in time.

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.

The gas-fired steam boiler is an essential equipment in the pharmaceutical process which provides a great deal of seam for steps such as sterilization, desiccation, tabletting and so on. Heilongjiang Jiren Pharmaceutical Co., Ltd., founded in 1996, is a state-level high-tech enterprise engaging in the research, development and production of traditional Chinese medicine. The company has five international advanced automatic production lines for capsule, tablet, suppository, granule and medicinal tea.

In order to implement the “coal to gas” project for environmental protection, Jiren Pharmaceutical decided to introduce highly-efficient gas-fired steam boiler produced by ZOZEN due to ZOZEN’s strong comprehensive competence, strict control of details and abundant cooperation experience with other enterprises in the pharmaceutical industry.

ZOZEN recommended WNS series condensing gas-fired steam boiler to Jiren Pharmaceutical according to the actual demands. To solve the problem of condensate water, ZOZEN  developed the recovery and sealing devices of condensate water and added devices such as condenser and economizer at the end of flue gas duct to lower the flue gas temperature to 60℃ and take full advantage of the sensible and latent heat of condensate water, which could not only solve the draining problem, but also improve the thermal efficiency to 98% and above.

ZOZEN Boiler improved the condensate water draining and recycling technology, which not only enhanced the enterprise’s economic benefits, but also effectively reduced the energy waste for all industries. The improvement of this detail showed ZOZEN’s determination to produce boilers with high quality, which adheres to the principle of “putting customer’s interest first”.
