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.
Root Zone Heating Systems for Greenhouses Root zone heating is an effective option for greenhouses that provides heat directly to the growing media rather than heating the air of the greenhouse. This approach provides a triple benefit for greenhouse growers: faster …

Mar 13, 2020· The primary challenge with greenhouse growing is stabilizing these temperature swings. Conventionally, people do this by blasting energy via heating or cooling systems into the greenhouse.
Combi Boiler. A combination boiler or combi boiler combines the utility of a high-efficiency water heater and the functionality of a central heating system into one compact unit. Combi boilers also don’t need separate hot water cylinders, which means they take up significantly less …
A greenhouse needs energy when the sun goes down and doesn’t need it, as much, when the sun comes up,” Zebley says. “It’s an on-and-off operation. To provide the heat for greenhouses during a relatively short period of time requires several large boilers, depending on the size of the greenhouse.”
Hot water from the boiler is circulated through a heat exchanger to heat the water in the buffer tank. At night when heat is needed, the hot water from the tank is circulated through the heat pipes or unit heaters in the greenhouse. This system will allow a smaller boiler to be installed as it can be operated continuously day and night.
Sizing a Greenhouse Heating System To find the right size heater, follow this step by step guide to calculate the amount of BTUH the heater needs to generate for the greenhouse. As an example, let’s use a GrowSpan Series 2000 Commercial Greenhouse that measures 35 ft wide by 96 ft long.
TK-Topboiler is a supplier of boilers, condensating heat exchangers and tanks for the horticultural industry. All our products are made and engineered in The Netherlands.
Apr 03, 2019· Virtual Grower, from USDA, is a decision support tool for greenhouse growers. Using this downloaded software, you can “virtually” build a greenhouse with a variety of materials for roofs and sidewalls, design the greenhouse style, schedule temperature set points throughout the year, and predict heating costs for over 230 sites within the US.
