series 5 packaged firetube boiler
Beiqi Panther car 6 tons of steam condensing one fuel gas steam series 5 packaged firetube boiler project has been successfully completed. This series boiler adopt advanced design concepts, using the waste heat of flue gas cascade, with the use of the condenser and the economizer fully absorb the waste heat in the flue gas, the boiler efficiency has been greatly improved.
Maximized efficiency with lower maintenance cost.
Each set of tubes that hot combustion flue gas travels through before making a turn within the boiler, is considered a “pass.” A four-pass boiler design consists of four sets of horizontal tubes, with the stack outlet at the front of the vessel. A downdraft design keeps the cooler water from having an effect on the hot surfaces within the boiler. 4-pass boilers leverage natural draft operation which allows cool water to contact the hottest part of the boiler.
The greenhouse heating series 5 packaged firetube boiler model selection, first look at the greenhouse heating area, the height of the greenhouse, greenhouse temperature requirements, heating several greenhouses, greenhouse material is what, choose what fuel in order to determine the boiler selection. Take the commonly used natural gas fuel as an example for reference.
How can we achieve the best thermal efficiency of the series 5 packaged firetube boiler :( a) an air preheater. One of the effective measures to improve the thermal efficiency of the boiler is the use of air preheater heat recovery. However, using the air preheater problem when using low sulfur fuel material prone to corrosion. In order to control such corrosion to some extent, how much fuel should be based on the sulfur content of the metal temperature a low-temperature region is set low limit. To this end, the flue gas temperature at the outlet of the air preheater also have a constraint. This can be determined to achieve a high thermal efficiency.
