YLW Coal Biomass Chain Grate Thermal Oil Boiler

YLW Biomass-fired thermal oil boiler is a horizontal chain grate stoker heating equipment. It uses biomass as fuel and flue gas as a heat source and uses heat transfer oil as a heat carrier to force the heat carrier to circulate in the liquid phase through a circulating oil pump to deliver heat to the heating equipment. After that, the recycled oil returns to the heating furnace. It is high-temperature, low-pressure, energy-saving equipment.
The heating temperature can be as high as 340℃, and the working pressure is generally below 1.0MPa, because it works in the liquid phase, which is safe and reliable.
  • Capacity: 1400KW-7000KW
  • Fuel: Straw, distiller’s grains, bagasse, other direct-burning fuel coal, biomass mixed fuel
  • Application: Chemical, printing and dyeing, food, wood processing, painting and other industries
  • YLW thermal oil boiler

Yongxing YLW type biomass heat-conducting oil boiler is a forced circulation chain grate stoker thermal oil boiler.

It is a new type of heating equipment that uses environmentally friendly energy-biomass as fuel and heat transfer oil as the medium. It consists of an upper body and a lower chain grate.

The thermal oil boiler The front part of the main body is the radiant heating surface of the furnace, the middle part is the heating surface composed of serpentine tube bundles, and the rear part is the convection surface. During operation, the boiler can be accurately adjusted according to actual requirements to meet different customer requirements. 

A better design is that a complete operation control system and safety monitoring device, which makes the operation of the boiler easier and more convenient.

Of course, our thermal oil boiler also runs very well when burning coal. Compared with other company boilers, our thermal oil boiler operating costs can save you 5%-10%.

YLW Coal Biomass Chain Grate Thermal Oil Boiler

1. Strong adaptability to different fuels
The combustion equipment and the upper furnace body are designed separately, and the furnace structure can be designed separately according to the different properties of the solid fuel;

2. Diversity of grate structure
The grate of this structure has two forms, fixed and fully automatic chain grate, and can be fed manually or mechanically according to the nature of the fuel.

3. Square coil combustion chamber
The boiler combustion chamber is composed of a refractory furnace chamber and a square coil, with sufficient fuel combustion space, complete combustion and high thermal efficiency.

4. The best coil design
The radiant section is made of square coiled tube, and the convection section is made of serpentine tube. The tube on the heating surface has good thermal expansion performance, low stress, safety and reliability.

5. The best process design
The flue gas is three-pass, the medium flows through the convection and radiant coils, the flow rate is uniform, and the operation is safe and stable.

6. Sufficient output
The heating surface is reasonably arranged, with large area, good heat transfer effect, high efficiency, stable and sufficient output.

7. Perfect automatic control measures
The oil output temperature is controlled accurately, and the medium temperature, pressure and super smoke temperature are set with multiple control protections to ensure safe and reliable operation.

8. Leading automatic control level
The boiler controller adopts Siemens/Delixi electrical components, with reliable performance. There are three types of controllers: common type, Chinese and English menu type with LCD display, and touch screen type with man-machine dialogue remote control. The standard configuration is ordinary.
