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.
Controls for HVAC, boilers, hot water heaters, alternative energy systems, and snow and ice melting systems help regulate operations with the goal of maximizing comfort, efficiency, system performance, and safety. Our controls offer popular features such as remote access to settings, Wi-Fi monitoring, zone synchronization, alerts, and more.
We offer controls for operating boilers and the mixing pumps that control the temperature in hot water heating system applications. Boiler and mixing control models include functions such as comfort adjustment and energy savers, as well as preconfigured control panels that make installation, operation, and maintenance easier.
Author: Bob Formisano The hot water from the boiler is blended with a proportion of the cooler water returning from the system to maintain the correct water temperature entering the system. In steam applications, these valves are often used in conjunction with one of our MPC Platinum series controls.
File Size: 2MB Our water heater controls help regulate operations with the goal of maximizing comfort, efficiency, system performance and safety. Our controls offer popular features such as touchscreen interface, diagnostics, accurate temperature control, remote access to settings and alerts.
Residential Hot Water Boiler Control - The average residential/light commercial boiler typically uses different controls to sequence the boiler. Boiler control in commercial and industrial applications can be very complex and can have added layers of controls outside of the local boiler controls that come from the manufacturer.
Indoor strap-on boiler controls provide high-limit, low-limit and circulator control without tapping the boiler or draining the system. Mounting strap offers any position mounting without leveling on a 2- to 6”-dia. pipe. Shop Grainger today for a reliable hot water control unit.
Here’s everything you need to know about Worcester Bosch boiler controls. Timers and Programmers. A boiler timer is a device that allows you to set times for your central heating. A programmer allows you to set different times, and temperature for heating and hot water. Note that old or defective boiler controls are a waste of energy and
