Coal‑fired (biomass‑fired) thermal oil heater
Coal‑fired (biomass‑fired) thermal oil heater
It is a closed‑cycle heating equipment fueled by wood; straw; biomass; coal; wood bark; rice straw; rice husk, with thermal oil as heat carrier. 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.
