boiler water wall tubes material

Power step-boiler water wall tubes material heating control law input sharing group, the group can be randomly put into or heating is stopped according to the load variation, and significantly reduce the impact on power. You can also manually start the same time, the number of heating zones to stop, user-friendly self-adjust electric power boiler. Control system controls the circulation pump start and stop in accordance with the temperature of boiler water. Hot water circulating pump is stopped when the furnace temperature reaches an upper limit, below the hot water circulation pump start lower limit temperature.

4.2MW WNS series hot water boiler water wall tubes material for Shanghai Jinshan Youth Practice Base

ZOZEN WNS series gas-fired hot water boilers are widely used in industries such as central heating, hotels, and hospitals. This series of gas-fired boilers adopts a wetback structure. The large-diameter corrugated furnace can not only effectively absorb the thermal expansion, but also increase the radiant heating area. With the advanced combustion equipment, this series of gas-fired boilerscan ensure the full combustion of the fuel, and the thermal efficiency can reach over 98%. And the WNS series boiler is a package boiler, which is fast to install and saves a lot of installation and capital investment costs. In terms of quality assurance, ZOZEN has established a strict quality management system. Each boiler needs to undergo strict quality inspection procedures to complete the final assembly.

Hot water boiler water wall tubes material is one of the important equipment for the district to provide our real estate company, and two gas hot water provide the fast boiler boiler flotilla of environmental performance, in full compliance with state regulations after smoke was detected in the rear of the boiler. And boiler operation is safe, stable, we use the very at ease. --customer feedback
