Thermal Oil Industrial Boiler Coal Fired Boiler Introduction
Thermal Oil Industrial Boiler Coal Fired Boiler is assembled chain grate boiler with forced circulation. The front of the boiler body is the radiation heating surface of the furnace, which is composed of double square coil tubes with dense row. The rear part is convection; Medium brush heating surface, composed of snakelike bundles.
YLW series horizontal type thermal oil boiler is an safe and energy saving boiler with working characteristics of low pressure (1.0 MPa) and high temperature (350℃). The combustion equipment is chain grate, the fuel could be II class bituminous coal and biomass pellet (wood chips, bagasse, straw, etc.). The heat carrier is heat conduction 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.
The boiler is composed of upper body and lower chain grate, which is installed on site. The air preheater is arranged behind the boiler. The high-temperature flue gas generated by combustion is partially sucked away in the furnace chamber, and then transferred to the convective heating surface for heat transfer through the smoke chamber. The flue gas is heated into the boiler in the air preheater, and then sent to the chimney by the induced draft fan through the dust collector and discharged into the atmosphere.
Thermal Oil Industrial Boiler Coal Fired Boiler Advantage
Digitized manufacture
- The laying-off of steel tube adopts CNC 3D laser cutting machine.
- The manufacture of square coil tube adopts CNC three-dimensional tube bending machine, no forced shaping.
- The manufacture of serpentuator adopts serpentuator automatic production line, once-forming.
Full argon arc welding
Square coil tube and coil tube all adopt argon arc welding technique,which guarantees tubes are 100% qualified.
Long life span
- The optimized radiation heating surface and convective heating surface, the medium flow is more reasonable, without overheat of the carrier and reduce the life;
- Convection section: optimize convection heating surface and adopt effective fix and structural support to make its working life longer.
- Set up effective flue gas partition for convection heating surface and cast partition to make it works longer.
Easy operation
- We have combustion arch patent, which is available for different types of coals, even the anthracite is very easy to burn.
- Flame-proof feeding bucket can avoid the feeding bucket is burnt and coking.
- There is ash cleaning unit, which is easy for maintaining, operating and cleaning.
Less fuel consumption
- Use superior refractory brick to build inside and superior perlite in the middle. Keep the furnace temperature under 50℃ to make the minimization of loss.
- Furnace adopts double close line coil, which makes heating surface sufficient.
