Gas-fired boilers and direct-fired gas turbines are two kinds of household heating devices that are widely used. Through the traditional gas supply, the boiler equipment can be operated and used.

The traditional gas supply is mainly carried out around the urban residents' cooking gas, and the gas boiler and direct gas turbine have a significant difference from the gas supply in pressure, flow, reliability and other aspects, and the gas regulator design plays an important role in the gas supply.

Composition and characteristics of gas supply system for gas-fired boiler and direct-fired gas turbine:

Composition of gas supply system at present, in the market, gas boilers and direct gas turbines generally use imported combustors which are more sophisticated to provide heat source, and the gas supply system is composed of two parts.A part of it is the attached equipment of the burner, which is composed of two main solenoid valves (the latter one with voltage stabilizer), a flow control valve, two ignition solenoid valves, ignition regulator, ball valve, orifice plate, anti-tempering device, rectifier plate and flame plate, etc.The other part belongs to the equipment provided by the gas supply enterprise, which is composed of gas regulator, filter, manual valve, overpressure cut-off valve, release valve and pressure gauge.

In recent years, the rapid growth of the number of gas-fired boilers and direct-fired gas turbines has greatly expanded and enriched the concept of traditional gas-fired applications. At the same time, due to the characteristics of such gas-fired equipment, it has also posed new challenges to the way of gas supply in the past.
