Various aspects, such as chemical production, food processing, and medical disinfection, require high-temperature steam from a steam boiler. Therefore, 4-ton gas-fired steam boilers are widely used in industrial fields. At present, there are many boiler manufacturers producing 4 tons of gas-fired steam boilers in the market, and the quality of equipment is mixed. Users and friends will inevitably feel confused when purchasing boilers. Zhengzhou Fangkuai Boiler Factory will tell you the price and selection of boilers within the normal range. Type skills.
There are many factors that determine the price of steam boilers, mainly operating efficiency, pollutant emissions, floor space, internal structure, service life, and so on. The higher the configuration of the boiler, the more expensive it will be, but the greater the benefits it will bring, it can be said that it has a very high cost performance. At present, the price of a 4-ton gas-fired steam boiler in the market is between US$30,000 and US$40,000.
Zhengzhou Fangkuai Boiler Factory would like to remind everyone here that the boiler must be equipped with appropriate safety valve facilities to ensure safety during operation.
The pulse safety valve is composed of the main safety valve, the pulse valve and the connecting pipeline.
The main safety valve is controlled by a small pulse valve. Under normal conditions, the main valve is tightly closed by high-pressure steam. When the vapor pressure exceeds the specified value. The small pulse valve is opened first, and the steam is introduced to the main valve piston through the steam guide tube. The pressure of the steam on the piston can overcome the force of the spring compression, so the main valve is opened to discharge the steam and the pressure; when the pressure drops to a certain value, The small pulse valve is closed. The steam flow on the piston is cut off, so the main relief valve is closed again. The residual steam on the piston can play a buffering role, so that the main valve is slowly closed to avoid damage to the valve clack and valve seat due to impact.
Recently, Zhengzhou Fangkuai Boiler Sales Co., Ltd. traveled to Dhaka, the capital of Bangladesh, to attend the Bangladesh International Textile, Knitwear & Garment Industry Exhibition (BTKG 2026). It showcased industrial thermal equipment and system solutions adapted to the whole process of textile printing and dyeing, actively expanding the South Asian market.
Bangladesh is an important global producer and exporter of textiles and garments. As a pillar local industry, the textile sector has long-term and strong demand for high-efficiency, stable and energy-saving industrial boilers and thermal equipment, with broad market potential. This exhibition participation is an important measure for Zhengzhou Fangkuai Boiler Sales Co., Ltd. to advance its internationalization strategy and further explore overseas markets.
Relying on its technological accumulation and manufacturing advantages in the field of thermal energy equipment, the company provides targeted thermal energy solutions for local textile, printing and dyeing, garment manufacturing and other industries, helping enterprises improve production efficiency and reduce operating costs.
