YLW Biomass Fired Thermal Oil Boiler

Hot oil boiler | Heat carrier boiler | Oil heating boiler

YLW series wood/biomass fired thermal oil boiler is horizontal grate combustion three-coil structure, wet back boiler. This boilers are fully automatic, energy saving and designed to operate on wide range of solid fuels, like coal, wood, husk, sawdust, multiple fuel options.

Thermal Capacity: 200-14,000kw/h 200,000-12,000,000Kcal/h
Rated Temperature: 200 ℃ ~ 320 ℃
Styles: horizontal / vertical
Available Fuel: coal, solid fuels, wood chip, bagasse, straw, and other biomass fuel
Applied Industries: wood industry, refinery&chemical, plastic and rubber, textile printing and dyeing, building material, machinery industry, food industry, etc.


  • YUANDA YLW coal or biomass fired thermal oil boiler is a thermal energy equipment for factory heating/drying. It can generate stable high temperature (maxium 350℃) under low pressure, with independently developed high-matching control system to release multiple linkages. Easy operation & ensure the equipment running 100% safety, which is an ideal industrial heat transfer equipment.

  • This thermal oil boiler capacity is 20,0000Kcal~20Mkcal / 120kw ~21,000kw. Hot oil outlet temperature is 280℃/320℃, or could adjusted by clients production requirements. Horizontal and vertical boiler two types.


  • Used in reactor, storage tank, oil tanks, asphalt/bitumen, hot press machine, fryer machine, resin reactors, rubber and plastics, adhesives, distillation columns, heat exchangers, drying processes, rotogravure and flexo printing, paints etc...

  • Types of Boilers We Offer:

  • types of boilers we offer



Three Layers Coil Tubes + 3-Pass Design

Effectively use the high temperature, smoke stay inside boiler to heat thermal oil 3 times, greatly reduce temperature of outlet  smoke, improve boiler thermal efficiency, energy saving, reduce fuel cost


Oil Cover Fire Structure + Wet Back Type

1. Pipline oil surround the fire, endothermic sufficient, heating up fast and evenly 2. Smoke transfer room is wet back structure, avoid burning deformation, ensure boiler lifespan


Double Layer 12cm Aluminum Silicate Insulation

We use double layer 12cm aluminum silicate insulation cotton, boiler surface temperature is not higher than 40 ℃, energy saving and high efficiency


Intelligent Monitoring, 100% Safe Running

PLC control, automatic data collection analysis system, over oil temperature/over smoke temperature/low flow alarm, easy for operate and make sure the safe
