Gas and steam boilers are exported to countries in the Middle East and West Asia rich in natural gas (such as Russia, Uzbekistan, Iran, Iraq, Saudi Arabia, Türkiye, India, Pakistan)
燃氣蒸汽鍋爐是以天然氣為燃料，在爐內燃燒放出來的熱量，加熱鍋內的水，并使其汽化成蒸汽的熱能轉換設備，水在鍋（鍋筒）中不斷被爐里氣體燃料燃燒釋放出來的能量加熱溫度升高并產生帶壓蒸汽。
Gas steam boiler is a thermal energy conversion equipment that uses natural gas as fuel, burns the heat released in the furnace, heats the water in the pot, and vaporizes it into steam. The water in the pot (drum) is continuously heated by the energy released by the combustion of gas fuel in the furnace, heating the temperature and producing pressurized steam.
Gas steam boiler adopts a wet back structure. The first return is the waveform furnace, and the second and third return are the smoke tubes. The boiler is equipped with fully automatic control devices and safety protection devices to achieve fully automatic water level control, alarm, and shutdown; Automatic control of outlet steam pressure and overpressure protection, automatic boiler ignition, burner firepower regulation and shutdown protection to ensure safe and economical operation of the boiler.
該產品的燃料為天然氣，燃料從燃燒器噴出，被電子點火棒點燃，在爐膽內微正壓燃燒。高壓煙氣由回燃室轉向180°入第二回程煙管，然后在前煙箱處再次轉向180°進入第三回程煙管后，經過煙箱經冷凝式節能器及煙囪排入大氣。
The fuel for this product is natural gas, which is sprayed out from the burner and ignited by an electronic ignition rod. It burns under slightly positive pressure inside the furnace. The high-pressure flue gas turns 180 ° from the combustion chamber into the second return flue pipe, and then turns 180 ° again at the front flue box into the third return flue pipe. After passing through the flue box, it is discharged into the atmosphere through a condensing energy-saving device and chimney.
