YGL Type of Vertical Fixed Grate Coal-fired Thermal oil Heater
• Simple structure, low cost.
• Adoption of top-mounted tube structure with large heat absorption area, high heat efficiency, never be collapsed.
• Heat transfer oi I enters into the boiler from the top and drains out from the bottom, which cannot easily be coked, with long service life of boiler.
• Remove ash once a month when burning Shenmu soft coal block for the product. Otherwise, ash may easily be deposited with bad heat transfer.

YGL Type of Vertical Spiral Lower-feed Coal-fired Thermal oil Heater
• Adoption of upward mechanically feed coal from the bottom is made, which malees coal divided into four layers (i. e. pre-heating layer, oxidation layer, combustion layer and burnout layer) for combustion. The volatile composition may fully be combustible when passing through the combustion layer to achieve objective of elimination of smolee and energy saving.
• Adoption of top-mounted tube structure with large heat absorption area, high heat efficiency, never been collapsed.
• Heat transfer oil enters into the boiler from the top and drains out from the bottom, which cannot easily be coleed, with long service life of boiler.
