YGL/YLL Vertical Thermal Fluid Heater

Hot oil heater | Wood/biomass fired hot oil boiler | Heat conduction oil boiler

YGL/YLL vertical thermal oil boiler is grate combustion three-coil structure, wet back oil heating boiler. This boiler required small footprint, space-saving, low cost, running stable. It designed to operate on a wide range of solid fuels, like coal, wood, husk, sawdust and multiple fuel options.

Thermal Capacity: 50-14,000kw/h 200,000-12,000,000Kcal/h
Temperature: 280 / 320 /350 ℃
Styles: Hand or automatic feeding
Available Fuel: coal, solid fuels, wood chip, bagasse, straw, and other biomass fuel
Applied Industries: textile printing and dyeing, refinery&chemical, plastic and rubber, wood industry, building material, machinery industry, food industry, etc.


  • YGL/YLL vertical thermal or thermic fluid heater use coal, wood, biomass or solid fuel as fuel, thermal oil as transfer medium, provides stable and uniform heating can be carried out with accurate temperature to the end user. Recent years, vertical thermic fluid heater is a popular heat transfer oil heater cause its space saved, less cost, longer lifespan.

  • YGL is the hand-feeding type vertical thermic oil heater with fixed grate, more cost effecttive. YLL is the automatic vertical thermic fluid heater, no need labor. The biggest difference between the two is the feeding method and slad remove, which is the bottom of the boiler. We manufactured fixed grate and chain grate thermic fluid heater. 

  • Main advantages: ①100% safty, over pressure, over temperature etc alarming ②save space, less civil works and low cost; ③We adopt three coil tubes layers with wet back, longer lifespan; ④Suitable for kinds solid fuel, wood waste, log, pellet, coal, palm shell, bagasse etc. ⑤External hot oil heater, prevent oil carbonization; ⑥Large open door design for easy maintenance; ⑦Can be pre-installed, made into skid-mounted, etc.

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

  • Besides, we have YY(q)L gas/diesel fired vertical thermic fluid heater, YLW horizontal thermal oil boiler, please contact us if you wanna use other fuel.



Oil Cover Fire Structure, Three Coil Pipes Wet Back

1. Increase radiant heating area, the boiler thermal efficiency is higher; 2. Prevent the boiler shell from deforming under high temperature; 3.Compact coil tube, no gaps,ensuring the flue gas flow


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, reduce fuel cost and high efficiency


Compact Boiler Structure & Small Footprint

Adopts vertical structure, occupy small area, low requirements for boiler room, reduce cost; 


Intelligent Monitoring, 100% Safe Running

PLC control, automatic data collection analysis system, over oil temperature/over smoke temperature/low flow alarm
