YGW Coal Thermal Fluid Boiler YGW Horizontal Coal Fired Thermal Fluid Boiler General Introduction This series thermal fluid boiler use heat transfer oil as medium. There is a hot oil circulating pump which in order to force the thermic fluid to flow in the closed loop circulation pipe. Then the thermal energy will be transfered to the heated object. The thermal fluid will back to the boiler furnace and be reheated. The YGW thermal fluid boiler can reach high temperature at low working pressure. It adopts advanced control system, equipped with liquid level controller, pressure controller, temperature controller, and alarms to make sure the boiler work orderly and safe. It is a safe boiler with high efficiency and low power consumption.
