WNS series horizontal internal combustion boiler is a boiler shell type 3 passes wetback oil/gas fired boiler. After fuel is being atomized by burner, flame is full of the wave furnace and transfer heat via furnace wall, this is 1st pass; the high temperature smoke is collected in reversal chamber and then enters 2nd pass which is grooved tubes bundle area; after heat convection, air temperature gradually falls and goes to front smoke box and turn to 3rd pass, which is smooth tubes bundle area, and then enters chimney passing back smoke box and exhausted to the atmosphere.
1. Digitized manufacture
The key part such as material cutting, rolling, drilling are proceeded by advanced CNC machining process to reduce the assemble stress and extend boiler working lifetime.
The front and back smoke chamber plates are cut by CNC plasma cutting machine and looks tidy and beautiful.
2.Easy operation and maintenance
Fully automatically operating, with automatically adjustment and protection of burning, water level, temperature and steam pressure.
3. Longer working life
Smoke tube and tube sheet connection is expanded first to eliminate the gap between them, then adopt automatic argon arc welding to relief the stress and expand boilers working life.
Longitudinal and girth joint adopt advanced automatic submerged-arc welding for good welding quality. All longitudinal and girth joint will have 100% radiographic inspection.
Fin tube us ND steel or stainless-steel material which avoid low temperature corrosion.
Inspection procedure point is set up to guarantee the sequence of expanding and welding, avoid cracking of the tube sheet holes.
4. Less fuel consumption
High quality aluminum silicate fiber is used with fire clay insulation, to control the boiler body temperature below 45℃ to control heat lost.
Sufficient steam storage room and heating area makes boiler to generate high quality steam and high thermal power.
Condenser is added to reuse the waste heat of the exhausted smoke to increase feeding water’s temperature and reduce emission temperature, which can increase the thermal efficiency above 98% and save operating cost.
File Size: 58KB Thermal Fluid Systems. Thermal fluid heating systems are a versatile type of indirect closed loop heating system that utilizes hot oil, water, water-glycol, or other synthetic mediums. We offer a variety of gas fired, oil fired, electric, and biomass-fired thermal fluid heaters and complete thermal fluid systems.
Author: Sigma Thermal It’s an environmentally friendly, non-toxic thermal fluid (heat transfer fluid) capable of providing precise temperature control. Rated to 600°F and specifically engineered to withstand the extreme oxidation environment of open (to atmosphere) systems, Duratherm 600 incorporates a proprietary dual-stage anti-oxidant for long, trouble free
Technical Data. A Division of Lubrizol. Preventing Fires In Thermal Oil Heat Transfer Systems. Thermal fluids have proven exceptionally safe in a wide range of industries. However, it is difficult to completely prevent fires in these systems because the necessary ingredients for a fire — fuel, air and ignition source — are present by design. The risk of fire can be minimized by observing sound design, …
Jul 01, 2001· Fire safety in thermal fluid systems depends on three measurements — flash point, fire point and autoignition temperature. Flash point The flash point of a fluid is the temperature at which sufficient vapor is generated for the fluid to flash when exposed to an ignition source.
Aug 11, 2014· Rather, the culprit in most cases is not the overheated thermal fluid but the equipment and systems conveying it. Specifically, blame can commonly be placed on poor choice of insulation materials, loss of flow, cracked heater tubes, or uncontained leakage.
Overheating of tubes. If the thermal ﬂux is too high, the HTF may degrade causing carbon build-up on the inside of the tube. As above, this reduces heat transfer and causes overheating of the tube wall. Eventually, failure can result. Overheating of tubes can result from insufﬁcient ﬂow of HTF through the tubes.
File Size: 179KB Thermal Fluid vs. Steam A thermal fluid (hot oil) system operates in a closed loop circulation system with minimal pressure. Fulton thermal fluid systems can reach 750°F (345°C) making them an ideal choice for many process heat applications. The choice between a steam system or a thermal fluid system is governed by the process requirements.
