Manual‑fired thermal oil boiler
Manual‑fired thermal oil heater
Hand‑fired coal‑fired thermal oil heater is a manual coal‑feeding heating equipment taking coal as fuel and thermal oil as heat carrier. It adopts hand‑fired fixed grate structure, realizes high‑temperature liquid‑phase circulating heat supply, and achieves high‑temperature heating under low pressure. Featuring low equipment investment and simple operation & maintenance, it is suitable for small‑and‑medium‑scale industrial heating working conditions.
