In the field of gas-fired steam boilers, WNS model is a relatively common type of gas-fired steam boiler. The full name of WNS is horizontal, internal combustion, and room-fired boiler equipment. The obvious characteristics of this type of boiler are the reasonable utilization of furnace space, proper structure and layout. Small footprint, high operating efficiency, stable operating state, etc.
Therefore, once it is introduced into the market, it has won the love and recognition of the majority of users, and the proportion of its use in the market has been increasing year by year.
Many users are very interested in gas-fired steam boilers, but do not know the selection of boilers and market prices. Zhengzhou Fangkuai Boiler Factory will come to answer your questions. Take a 10-ton gas-fired steam boiler as an example.
At present, the market price of 10-ton gas-fired steam boilers in the market generally ranges between 80,000 and 120,000 US dollars. As for the high intermediate price, it is mainly because of the difference in boiler operating efficiency and quality. The boiler equipment with high operating efficiency is in use. It must be very energy-saving and money-saving, so when you buy a boiler, you should not only look at the purchase cost, but also take into account the later operating costs, so that the boiler can better serve us.
Zhengzhou Fangkuai Boiler Factory also reminds everyone of the importance of safety valves in gas-fired steam boiler equipment.
Safety valve is a safety device installed to prevent explosion caused by excessive pressure in equipment and container under abnormal conditions.
When the pressure in the equipment is too high, the safety valve automatically opens, and then automatically closes when the pressure drops to a safe range to prevent the equipment from exploding due to excessive pressure. Generally, the constant pressure of the safety valve is 0.5 to 1.10 times of the operating pressure.
According to its structure and principle of action, the safety valve is divided into gravity type, lever type, spring type and so on. The lever type is more suitable when the working temperature is high and the pressure is not too high; the spring type should be used for high-pressure equipment; generally, the spring type safety valve is commonly used.
We, Zhengzhou Fangkuai Boiler Co., Ltd. (Fangkuai), are excited to announce our participation in the Indonesia International Heating Technology Exhibition 2025. We will be showcasing our advanced boiler systems engineered for higher efficiency, lower emissions, and sustainable energy performance.
