Regarding the fact that many enterprises currently use coal-fired boilers, partial modifications can be made without the need to replace the boiler body.
1. Internal renovation of boiler
Replace the combustion system and use a natural gas burner head. There is no need to make any changes inside the body, just perform internal cleaning.
2. Gas source renovation
Because the original methods were coal or oil, now natural gas is used. So when used at the gas source end, the corresponding gas pressure regulating pry is installed. And connected to the combustion engine head through pipelines, forming a circuit.
