YY(Q)W series hot oil boiler is horizontal type boiler with oil or gas as the fuel. Thermal oil boiler is a new type heating equipment with heat conduction oil as the heat carrier, through the circulating pump to transfer the heat to other required heating equipments

YY (Q) W series thermal oil boiler is a kind of boiler which uses gas(oil) as fuel ,thermic oil as medium, hot oil circulation pump to make the medium to forced circulation, deliver the heat to heating need equipments and then go back to the heating furnace.It can obtain a high operating temperature at low pressure and can do high-precision control on the medium.
1.High operating temperatures can be achieved under very atmospheric conditions. Greatly reduce operating pressure and safety requirements of the high-temperature heating system, improve the reliability of the system and equipment;
2. Satisfy all different temperature heating and cooling process requirements in a wider temperature range, besides, it can achieve the high-temperature heating and low-temperature cooling process requirements by using same heat-conducting oil in same system and same time. Reduce the complexity of system and operation;
3. The water treatment system and equipment are omitted, improve system thermal efficiency, reduce maintenance workload of equipment and pipelines. So that we can reduce the initial investment and operating costs of the heating system;
4. In the case of accidental system leakage, heat-conducting oil and open flame may burn. This is a problem need to pay attention compared to the water vapor system. However, promise there is no leakage, operating under low pressure, its operation safety is higher than that of water and steam systems.

Jute boiler, steam boiler capacity 0.3ton-10ton, generally use jute/waste cloth/waste fabric burning to supply thermal power in garment factory.

DZL series coal fired horizontal type packaged boiler is single drum longitudinal type with natural circulation, the main components are installed within the factory. After installing the large parts, just need to setup pipeline, instrumentation valves, flue duct, and slag extractor, etc, connect water and electricity power, and incorporated into the heating network system, then the boiler could operate.
This boiler is consisted of boiler drum, furnace and convection pass, which are made up of two sides water-cooled tubes, the front smoke box is consisted of four casing pipes and front tube plate, the boiler drum is equipped with thread convection tubes. Chain grate is under the water cooling system, to support the whole boiler body, to form a packaged boiler.
