Coal water slurry fired thermal oil heater is a kind of special industrial furnace which uses coal water slurry (CWS) as the fuel, the furnace takes heat carrier oil as medium and uses the hot oil circulating pump force the medium to make liquid circulation; then the thermal energy will be transmitted to the devices and back to the furnace to be reheated. Two return structures enhance the thermal efficiency and lower flue gas temperature. Thicker insulated material layer makes radiating at minimum limit. All boilers are assembly structure which is easy for installation by just connecting system device by pipes. Intelligent system control makes boiler operation easier and simpler. Controller with imitation screen display has auto igniting, burning, circulation pumps control, alarm, etc. functions
Advantage Feature of Thermal Oil Heaters
- Environment friendly, energy saving and, high efficiency: coal combustion efficiency reach above 98%., thermal efficiency reach above 85%
- Wide and simple load adjustment range: load range can adjust from 35% to 100%, economical choice.
- Covering area Saving: Coal-water slurry and coal power transport in airtight canning, no dust pollution, no need coal storage yard and slag yard, improve the use ratio of land, save 50% land area.
- Low fuel cost with high intelligent automatic control: save human resource, coal fired boiler need 6-7 worker coal-water only need two workers, save fuel beyond 20%. Improve the sanitary condition and alleviate worker labor Coal water slurry thermal oil heater has become an ideal substitute for oil and gas fired steam boiler.
- Low temperature combustion: Coal water boiler can heat up to and maintain 900℃-1200 ℃ in a very little time, which avoid the Incomplete combustion during the low temperature period, also avoid producing the NOx of oil fired boiler when temperature is above 1300℃
- Clean flue gas emission: CWS boiler dust emission concentration is about 100mg/Nm3 . which is 1/2 of the national emission standard 200 mg/Nm3. ash can be used as material of building and cement after closed dry ash collection system ,
