Gas‑fired & Oil‑fired Thermal Oil Heater
Gas‑fired & Oil‑fired Thermal Oil Heater
It is a closed‑cycle heating equipment fueled by fuel oil (diesel, heavy oil) or gas (natural gas, liquefied petroleum gas), with thermal oil as the heat‑transfer medium. The circulating pump forces liquid‑phase circulation of thermal oil, which transfers heat to heat‑consuming equipment and then returns for reheating, realizing low‑temperature high‑pressure, high‑efficiency and stable heat supply.
