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.
Safety and control systems. Alfa Laval Aalborg's thermal fluid systems can be supplied with an in-house developed PLC-operate control panel. Through the 12inch touch screen of this control panel, the operator has a clear overview of the complete heating system and its status.
Fluid heating and pumping services, which ensure proper circulation and transport of fluids into systems, vessels, and pipelines, are very important in the energy industry. 8,000,000 BTU/hr fired heating units. The FourQuest Energy fired heating units are coupled with a shell and tube heat exchanger using glycol as a heating medium.

A thermal fluid system is more than just a heater, and all the components of the system must work together in harmony for proper performance. Purchasing a complete thermal fluid system from Sigma Thermal will ensure that your system operation functions reliably.
Thermal Fluid Heaters. Thermal fluid heaters use a liquid medium to transfer heat energy into a process through a closed loop system. Through use of thermal oils or glycols higher operating temperatures can be safely achieved than is practical with steam systems, making thermal heaters easier than common steam systems to operate and maintain.

HC-1 Thermal Fluid Heaters The HC-1 thermal fluid heater is available in standard sizes from 1 to 30 MM Btu/hr. Configuration options include vertical up-fired, vertical down-fired, and horizontal. Custom heater designs are also available to meet a wide variety of project-specific design challenges.
The mono-tube, horizontal or vertical helical coil actually is the entire combustion chamber. Gases leaving the combustion chamber are passed over the entire outside surface of the coil to use all available heat. The thermal fluid flows through the coil, eliminating the possibility of vapor lock or …
Author: Manufacturing Today Thermal fluid heating systems use indirect methods for heating a substance or system. The heater is used to heat an intermediate liquid (often water, thermal oil or glycol). This intermediate liquid is then used to transfer heat to the end target. The end target can be process equipment, or other liquids during transfer or while […]
