Feb 06, 2017 · The hot flue gas then passes through the boiler components that turn water into superheated steam. This steam powers the turbine generator and then goes to an air-cooled heat exchanger, where it condenses into water and returns to the power cycle. The flue gas exiting the boiler has cooled enough to enter the emissions control system.

Read MoreDec 31, 2021 · To Ease Uncertainty, Growers Turn to Biomass Boilers. Natural gas has long been the preferred fuel choice for commercial greenhouse boilers — and it's not just because of its historically low price. Natural gas burns efficiently; 90% or more of its available energy is converted to warm vegetables and fruits.

Both pipe options provide gentle, radiant heat for plants and don't require welding. TrueLeaf.net. Infinite Energy 2 Condensing Boiler (Delta T Solutions) With up to 98
Read MoreFeb 05, 2015 · Heating Systems. Biomass boilers can be a cheaper alternative to oil and gas heating systems because the solid-fueled heating system can have quicker payback rates. To take advantage of that benefit growers must be sure their biomass system is a fine-tuned, wholly optimized machine. Be sure your fuel feed is continuous.
Read MoreJun 04, 2019 · Condensing boilers have to have low return water from the radiators to work best. With water at 130°F, 15% of the water vapor will condense, whereas at 60°F, over 90% of the water vapor will condense. A root zone system with return water at 80 to 90°F is a good example of where it will work well.
