Case Introduction

A 4-ton gas-fired steam boiler for a biopharmaceutical plant in Pingdingshan, Henan


The gas boiler recommended by Zhengzhou Fangkuai Boiler has been put into use after trial operation, and it can fully meet our steam demand. The boiler output is sufficient, the steam quality is high, and the exhaust gas emissions are also very small, which fully meets our original procurement standards.

Project proposals

The cooperation with Zhengzhou Fangkuai Boiler this time is a biopharmaceutical factory located in Pingdingshan City, Henan Province. The steam boiler plays an important role in the process of drying, cooling, granulating, and tableting during the production of medicines. The pharmaceutical company has multiple production lines for capsules, tablets, suppositories, powder injection filling, tumor drugs, etc., so the demand for steam is very large. At the same time, the company decided to purchase a gas-fired steam boiler in response to my country's environmental protection policy. Zhengzhou Fangkuai Boiler recommended a 4-ton condensing gas-fired steam boiler (WNS4-1.25-Y.Q) according to its actual demand for steam consumption.

Product advantages

This series of steam boilers use a new technology of heat exchange element "wing tube" instead of the outer fin tube, cooling water circulates outside the tube, avoiding the defects that the fin tube is easy to scale and difficult to clean. At the same time, because of the unique "wing tube" The design of the tearing groove increases the heat exchange area by 5 times under the same volume, the latent heat of vaporization in the flue gas is fully absorbed, the energy is effectively used, and the efficiency is higher. At the same time, the boiler adopts the heat exchange method of air and flue gas convection to further absorb the latent heat of flue gas, and send the air heated by the air preheater to the burner through the connecting pipe to provide warm air for combustion and improve combustion efficiency. Fans that can be controlled by frequency conversion have greater freedom and finer combustion adjustment. The boiler can run smoothly under a variety of different working conditions.
