Product Description
"REACH BOILER" YLW series horizontal type thermal oil boiler is an safe and energy saving boiler with working characteristics of low pressure (1.0 MPa) and high temperature (350ºC). The combustion equipment is chain grate, the fuel could be II class bituminous coal and biomass pellet (wood chips, bagasse, s traw, etc. ). The heat carrier is heat conduction oil, the circulating pump force heat transfer medium circulating in liquid phrase, and transfer heat to heat user equipment, then return to the heating furnace for reheating. Because of working in liquid state, the vertical type coal/biomass fired thermal fluid heater is safe and reliable.
1. Maximum operating temperature 320 °C.
2. Pipe explosion-proof device.
3. Oil discharge and return temperature display.
4. Isolated electrical control box to extend the service life of electrical appliances.
5. Hot oil BY-PASS pressure relief circuit.
6. Oil pump horsepower and heating power can be customized.
7. Electrical components mainly adopt OMRON, FUJI, TE, LS, SIEMENS, ABB, JUMO.
8. Adopt skid-mounted type module design, easy to install and easy to operate.
9. Using multi-layer coils for heat exchange, the heat receiving area is sufficiently arranged, the surface heat load is low, so that the heat-conducting oil is not easy to coke and accumulate carbon.

Technical Advantages Safety
Boiler body uses the forced circulation in the high temperature area to make sure all heating areas can be cooled down and avoid vaporization; The explosion door and flame detector are equipped for safe and reliable operation. Comb plates are used between both sides of boiler and tube bundle to avoid leakage of condensate and gas caused by using refractory concrete as sealing material. Air proof test is done before delivery in the factory to guarantee any gas leakage problem.
Environmental protection
Big combustion chamber equipped with Low emission combustion burner effectively reduce the NOx to 30mg/m3. Smoke duct and smoke outlet use internal insulation to reduce operating noise.
Combustion chamber uses full membrane water cooling wall structure and pressurized combustion without smoke mixture.
Energy conservation
Good quality alumina silicate fiber and fire clay insulation material are used and the boiler body temperature is controlled below 45ºC and greatly heat loss is reduced. Combustion chamber is designed with narrow distance tube membrane water cooling wall which has good air proof to reduce heat lost and increase boiler thermal efficiency. Internal inspection holes uses high-alumina refractory and manhole cover seal devices, solving superheat problem in this part caused by using refractory bricks.
Convenience
Manholes are placed on the front and back side of drums and inspection doors on back side of boiler easy to open for inspection and clean inner and outer parts.
Longer lifespan
Membrane structure are used in the front and back wall for boiler body and highly increased their lifespan to over 20 years.
The key processes including material cutting, rolling, drilling are done by advanced CNC machining process to reduce the assembly stress and extend boiler service lifetime.
Flutter prevention fastener is used for high temperature part convection tubes, which avoid convection tube cracking problem.
Longitudinal and girth joint adopt advanced automatic submerged-arc welding for good welding quality. All longitudinal and girth joint will be tested by radiographic inspection.
