According to the difference in output medium, gas boilers are divided into gas steam boilers and gas hot water boilers. A 4-ton boiler refers to boiler equipment that outputs 4 tons of steam or 4 tons of high-temperature hot water per hour. This is a brief introduction for you. Explanation of boiler model parameters. For users who need to purchase boilers, what are the parameters and prices of 4-ton gas boilers are questions worthy of attention, let Zhengzhou Fangkuai Boiler Factory answer for you.
First of all, according to the difference of the output medium, Zhengzhou Fangkuai Boiler Factory will separately describe the parameters of the steam boiler and the hot water boiler.
Parameters of 4 ton gas boiler (steam):
The total electric power of burning heavy oil is 26.2KW of three-phase electricity;
The total electric power of burning light oil is 13.0KW of three-phase electricity;
The total gas electric power of three-phase electricity is 13.0KW;
Parameters of 4 ton gas boiler (hot water):
The total electric power of burning heavy oil is 22.2KW of three-phase electricity;
The total electric power of burning light oil is 9KW of three-phase electricity;
The total gas electric power of three-phase electricity is 6.5KW;
Recently, some users are consulting Zhengzhou Fangkuai Boiler Plant about the selling price of steam boilers. The user needs to purchase steam boilers for processing and production in food plants. For this reason, the technical engineer of Zhengzhou Fangkuai Boiler Factory recommended a 4-ton gas-fired steam boiler for the user after understanding the user’s needs in detail and visiting the user’s site for on-site inspection. The current price of the equipment is between RMB 250,000 and RMB 350,000. Wait.
