With the rapid development of China's economy, the traditional coal-fired technology makes a large number of carbon dioxide and sulfur dioxide emissions into the air, resulting in air and water pollution. In recent years, environmental protection organizations all over the country attach great importance to environmental governance, and have achieved remarkable results in rectifying enterprises whose emissions do not meet the standards within a time limit.

隨著天然氣的推廣應(yīng)用，山東燃?xì)忮仩t逐漸走到人們的日常生活之中，代替了燃煤鍋爐成為家庭和工廠的重要采暖工具。與煤炭相比，天然氣具有清潔、無污染、熱值高等優(yōu)點，隨著天然氣資源的開發(fā)，我國的能源消耗由過去的燃煤、燃油逐漸向燃?xì)獍l(fā)展，大量的燃煤鍋爐也逐漸被燃?xì)忮仩t所取代，在今后的一段時期內(nèi)，山東燃?xì)忮仩t的應(yīng)用前景會更加廣闊。

With the popularization and application of natural gas, Shandong gas-fired boilers have gradually come into people's daily life, replacing coal-fired boilers as important heating tools for families and factories. Compared with coal, natural gas has the advantages of cleanliness, non-pollution and high calorific value. With the development of natural gas resources, energy consumption in China has gradually changed from coal-fired and oil-fired to gas-fired, and a large number of coal-fired boilers have gradually been replaced by gas-fired boilers. In the future, the application prospects of Shandong gas-fired boilers will be broader.

The characteristics of gas combustion are clean, easy to transport, ash-free, easy to adjust combustion, good operation and easy to adjust calorific value. Gas combustion modes are generally divided into diffusion combustion, atmospheric combustion and flameless combustion according to the supply mode and quantity. Diffusion combustion refers to the combustion of gas without premixing air before combustion, that is, no primary air supply. Its combustion characteristics are that the mixing of gas and air is realized by the diffusion between gas and air. This kind of combustion has the advantages of low combustion speed, low flame thermal intensity and easy to produce chemical incomplete combustion. It has no tempering phenomenon, high deflagration rate and stable combustion.

大氣式燃燒又稱本生式燃燒，它是在燃燒前預(yù)先混入一部分空氣，一次空氣的供給一般靠引射吸入，它的燃燒火焰由內(nèi)外兩部分組成，內(nèi)焰呈青藍(lán)色，輪廓清晰，短而有力；外焰呈淡藍(lán)色，燃燒溫度提高，減少了不完全燃燒，但易發(fā)生回火或脫火現(xiàn)象。無焰式燃燒是燃?xì)馊紵?，燃?xì)馀c所需空氣完全混合，并有高溫點火源的存在，燃燒過程在瞬間完成，火焰很短，好像無火焰一般，其燃燒特點是燃燒完全、燃燒溫度高，熱效率高，赤熱的燃燒板表面可產(chǎn)生紅外線輻射。燃?xì)忮仩t對燃燒器的特殊要求是燃燒器的燃燒完全程度高，調(diào)節(jié)性能高、容量范圍廣。目前，燃?xì)馊紵饔兄比家L(fēng)式擴散燃燒器、鼓風(fēng)式擴散燃燒器，引射式燃燒器等。

Atmospheric combustion, also known as Bensheng combustion, is pre-mixed with a part of air before combustion. The supply of primary air is usually inhaled by ejection. Its combustion flame consists of internal and external parts. The internal flame is blue-blue, clear outline, short and powerful; the external flame is light blue, the combustion temperature increases, which reduces incomplete combustion, but tempering or detachment easily occurs. Flameless combustion is that before the combustion of gas, the gas is completely mixed with the required air, and there is a high temperature ignition source. The combustion process is completed in an instant, the flame is very short, like no flame. Its combustion characteristics are complete combustion, high combustion temperature, high thermal efficiency, and infrared radiation can be generated on the surface of the red-hot burning plate. The special requirements of gas-fired boilers for burners are high burning degree, high regulating performance and wide capacity range. At present, gas burners include direct-fired induced-air diffusive burner, blast diffusive burner, ejector burner, etc.
