Product Overview
The YLW Series Horizontal Biomass/Coal-Fired Chain-Grate Thermal Oil Heater is designed for reliable, high-temperature industrial process heating using solid fuels. Featuring an automatic chain-grate combustion system, a horizontal three-pass flue gas structure, and a combination of square radiant coils and serpentine convective coils, it delivers efficient heat transfer and stable thermal oil circulation at temperatures up to 340°C. Its split-type furnace and grate design allows combustion chamber customization according to different coal and biomass characteristics, while intelligent Siemens or Delixi control components provide precise temperature regulation and comprehensive safety interlocks. With automatic fuel feeding, mechanical ash discharge, and a robust thermal oil heating system, the YLW Series is suitable for continuous industrial operation and demanding process heating applications.

Key Advantages
Delivers thermal oil temperatures up to 340°C at a typical operating pressure below 1.0 MPa, supporting high-temperature processes without relying on high-pressure steam.
Provides continuous, uniform fuel feeding and automatic ash discharge, reducing manual labor and maintaining stable combustion.
Supports stable heat delivery and efficient process temperature control, helping reduce energy consumption and long-term operating costs.
Features a separate furnace and chain-grate configuration, allowing furnace volume and front and rear arches to be customized for different solid fuels.
Combines square radiant coils with serpentine convective coils to improve heat transfer, accommodate thermal expansion, and reduce localized structural stress.
Uses Siemens or Delixi electrical components with multi-level safety interlocks for temperature, pressure, and exhaust heat monitoring. The control system is designed to maintain thermal oil outlet temperature accuracy of ±1°C under suitable operating conditions.
Typical Applications
