Hot oil boiler is a kind of safe and energy saving boiler with working characteristics of low pressure (1.1 MPa) and high temperature (350℃). The heat carrier is hot oil (heat conduction oil/heat transfer oil), the circulating pump force heat transfer medium circulating in liquid phrase, and transfer heat to heat user equipment, then return to the heating furnace for reheating. Because of working in liquid state, the vertical type coal/biomass fired thermal fluid heater is safe and reliable.
What is Hot Oil?
Hot oil has a high boiling point, it usually used for the industries that need the temperature of 150~350℃, to instead of steam. The hot oil has the advantages of high transfer efficiency, fast heat transfer, and good thermal stability.
As the heat-transfer medium, hot oil has the characteristics of:
1. Achieve high operation temperature (350℃), under the low working pressure (<1.1Mpa).
2. Decrease the working pressure of high temperature heating system, improve safety and stability of system and equipment.
3. Fit for process requirement on wider temperature range.

Peculiarities of YLW Series Hot Oil Boiler

1.Sitong boiler can adopt low quality thermic oil.
2.The spiral diameter can be customized as per your request.
3.The furnace structure can be designed based on different fuels, strong adaptability of different fuels.
4.The grate could be designed as fixed and moving, based on the fuel properties.
5.Complete operating control and safety monitoring devices, ensure safe and reliable operation
6.Large diameter combustion chamber, combustion sufficient and improve thermal efficiency.
7.Adopts advanced coil design and three pass structure, operate reliable.
8.Saving energy and reducing consumption, compared with the steam boiler it can save energy 1 to 1.5 times.

Application of Hot Oil Boiler
Owing to its characteristics of high heating temperature, low working pressure, energy saving, thermal oil boiler can be widely used in a variety of industrial heating process. Instead of electricity, steam heating, and it can improve the productivity.
1. Synthetic fiber industry: polymerization, melting, spinning, extension, dry .
2. Textile printing and dyeing industry: hot finalize the design, thermosol dyeing, baking, calender, drying and hot air stenter.
3. Plastic and rubber industry: hot-press, hot-extent, extrusion, vulcanization molding, calendering, injection, mucilage mixer, conveyor dryer.
4. Paper industry: drying, corrugated paper processing, calender, glue roller.
5. Wood industry: plywood, density board, hot pressing molding, wood drying, steaming equipment.
6. Building materials industry: plasterboard drying, asphalt heating, emulsified asphalt, asphalt concrete, concrete component maintenance, drying equipment, linoleum production line.
7. Food processing industry: grain drying, bakery, etc.
