Overview

Automatic Coal Fired Hot Oil Boiler For Electric With Temperature Control


Product Detail:

YLW series of horizontal, coal-fired, chain grate, Thermal Oil Boiler (also called hot oil boiler, thermal fluid boiler) are used in many industrial applications where efficiency and accurate temperature control between 100-300℃ are required. They work in the way of heating directly thermal fluid in the pipes with the high temperature smoke. With the help of forced circulation oil pumps, the fluid with high temperature goes into the heat-required equipments, like dryer, and then comes back to the boiler and is re-heated again. The shell plate is made of Q235-A/B steel plate. The outside insulation is aluminium silicate fibrofelt with thickness of 150mm. The boiler is packed by 2mm guard shield. There are two kinds of dust collectors for your choice: cyclone and scrubber. The dust removal efficiency of the first one is up to 95%. While the one of the second one is up to 95% and at the same time SOx and NOx removal efficiency is up to 98%. CHUANGSHENG has many years experience in this field and we can offer a broad range of products, service and support.

Boiler Features


1. High heat efficiency, unique structure, the heat efficiency can be more than 78%.

2. Furnace radiation area adopts double square shaped coiler and on the top of boiler, we design the ceiling pipes, so that the heat load can be reduced on the surface of pipes and the thermal oil can work more safely.

3. In the end of boiler, we design a heating area with staggered arrangement. That will enhance the heat transfer coefficient and decrease the ash deposit in the boiler.

4. The unique design of furnace arch with our own patent can make the coal burn out fully to enhance the heat efficiency.

5. The convection area is equipped with an all-direction soot blower. This will reduce the difficulty of cleaning ash and prolong the service time.

6. High safety. When abnormal conditions happen, safety interlock system starts up tp protect the boiler system.

7. Accurate temperature control. 

8. The boiler can be equipped with a waste heat boiler in the rear, if users need hot water or steam from the heating system. That makes full use of the exhausted smoke to achieve energy-saving and environmental protection.
