Gas fired boiler and gas direct fired machine are two kinds of household heating devices which are widely used. Through the traditional gas supply, the operation of boiler equipment can be met and used. Electromagnetic induction boiler

傳統的燃氣供應主要是圍繞城市居民炊事用氣而進行的,而燃氣鍋爐、直燃機對燃氣供應在壓力、流量、可靠性等方麵與灶具有著顯著的區別,燃氣供應中起重要作用的燃氣調壓器的選型設計。

The traditional gas supply is mainly around the city residents cooking gas, and the gas boiler, direct fired machine for gas supply in pressure, flow, reliability and other aspects has a significant difference with the stove, gas supply plays an important role in the selection of gas regulator design.

燃氣鍋爐和直燃機燃氣供應係統組成及特點：

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

燃氣供應係統組成目前,市場上燃氣鍋爐、直燃機一般采用較為精 密的進口燃燒機提供熱源,燃氣供應係統由兩部分組成。一部分屬於燃燒器自帶的附屬設備,它由兩個主電磁閥(其中後一個帶有穩壓裝置)、一個流量調節閥、兩個點火電磁閥、點火調節器、球閥、節流孔板、防回火裝置、整流板及穩焰板等組成;另一部分屬於燃氣供應企業提供的設備,由燃氣調壓器、過濾器、手動閥門、超壓切斷閥、放散閥、壓力表等組成。

The composition of gas supply system at present, the gas boiler and direct fired machine in the market generally use more precise imported combustion machine to provide heat source, and the gas supply system is composed of two parts. One part belongs to the accessory equipment of the burner, which is composed of two main solenoid valves (the latter one is equipped with pressure stabilizing device), one flow regulating valve, two ignition solenoid valves, ignition regulator, ball valve, orifice plate, anti backfire device, rectifying plate and flame stabilizing plate, etc; The other part belongs to the equipment provided by gas supply enterprises, which is composed of gas regulator, filter, manual valve, overpressure shut-off valve, vent valve, pressure gauge, etc.

近年來,燃氣鍋爐和燃氣直燃機數量的迅速增長大大拓展和豐富了傳統燃氣應用的概念,同時由於此類用氣設備自身的特點,也對過去燃氣供應的方式提出了新的挑戰。

In recent years, the rapid growth of the number of gas-fired boilers and gas-fired direct fired machines greatly expands and enriches the concept of traditional gas application. At the same time, due to the characteristics of such gas equipment, it also puts forward new challenges to the way of gas supply in the past.
