燃氣熔鹽爐 燃氣熔鹽加熱爐（Gas molten salt furnace Gas molten salt heating furnace）
燃氣熔鹽爐是以天然氣為燃料，以熔鹽為熱載體，利用熔鹽泵強制液相循環，將熱能輸送給用熱設備，繼而返回重新加熱的直流式特種工業爐。整個系統由熔鹽供熱系統、燃燒系統及控制系統構成:
Gas molten salt furnace is a special industrial furnace that uses natural gas as fuel and molten salt as a heat carrier. It uses a molten salt pump to force liquid-phase circulation, transfer heat energy to the heating equipment, and then return it to reheat. The entire system consists of a molten salt heating system, a combustion system, and a control system:
熔鹽供熱系統由熔鹽爐本體、熔鹽泵、熔鹽槽及有關輸送管線、閥門組成。
The molten salt heating system consists of the molten salt furnace body, molten salt pump, molten salt tank, and related conveying pipelines and valves
燃燒系統：主要由燃氣供給系統、燃燒器、熔鹽爐、煙道防爆門、空氣預熱器、煙氣余熱換熱器、煙囪及有關閥門管線組成。
Combustion system: mainly composed of gas supply system, burner, molten salt furnace, flue explosion-proof door, air preheater, flue gas waste heat exchanger, chimney, and related valve pipelines.
控制系統分為動力控制和儀表顯示控制兩部分。
The control system is divided into two parts: power control and instrument display control.
動力控制主要控制熔鹽罐內的電加熱器，熔鹽循環泵、風機、燃燒器等設備的起動與停止，同時循環泵與燃燒器之間進行聯鎖控制以保證加熱爐的安全運行。Power control mainly controls the start and stop of the electric heater, molten salt circulation pump, fan, burner and other equipment in the molten salt tank. At the same time, interlocking control is carried out between the circulation pump and burner to ensure the safe operation of the heating
儀表顯示控制：熔鹽爐負荷是根據智能儀表出口油溫的設置，通過儀表智能計算，進行 PID 調節功能， 自動調節 燃料量與空氣供給量，以充分滿足控制要求.
Instrument display control: The load of the molten salt furnace is set based on the outlet oil temperature of the intelligent instrument. Through intelligent calculation by the instrument, PID adjustment function is performed to automatically adjust the fuel and air supply to fully meet the control requirements
燃氣熔鹽爐廣泛應用在固堿蒸發濃縮、三聚氰胺制取、氫氧化鋁溶出、廢液廢油高溫再生等化工單位；也可應用在太陽能光熱發電的儲能。
Gas molten salt furnaces are widely used in chemical units such as solid alkali evaporation concentration, melamine production, aluminum hydroxide leaching, and high-temperature regeneration of waste liquid and oil; It can also be used for energy storage in solar thermal power generation.
燃氣熔鹽爐出口應用于天燃氣豐富的中東和西亞國家（如俄羅斯，烏磁別克斯坦，伊郎，伊拉克，沙特阿拉伯，土耳其，印度，巴基斯坦）各種需要進行高溫加熱的各行各業。
The export of gas-fired molten salt furnaces is used in various industries requiring high-temperature heating in Middle East and West Asia countries rich in natural gas (such as Russia, Ukraine, Iran, Iraq, Saudi Arabia, Türkiye, India, Pakistan).
