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

传统的燃气供应主要是围绕城市居民炊事用气而进行的,而燃气锅炉、直燃机对燃气供应在压力、流量、可靠性等方面与灶具有着显著的区别,燃气供应中起重要作用的燃气调压器的选型设计。

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.

燃气锅炉和直燃机燃气供应系统组成及特点：

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

燃气供应系统组成目前,市场上燃气锅炉、直燃机一般采用较为精 密的进口燃烧机提供热源,燃气供应系统由两部分组成。一部分属于燃烧器自带的附属设备,它由两个主电磁阀(其中后一个带有稳压装置)、一个流量调节阀、两个点火电磁阀、点火调节器、球阀、节流孔板、防回火装置、整流板及稳焰板等组成;另一部分属于燃气供应企业提供的设备,由燃气调压器、过滤器、手动阀门、超压切断阀、放散阀、压力表等组成。

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.

近年来,燃气锅炉和燃气直燃机数量的迅速增长大大拓展和丰富了传统燃气应用的概念,同时由于此类用气设备自身的特点,也对过去燃气供应的方式提出了新的挑战。

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.
