large regenerative boiler

large regenerative boiler are horizontal three-pass water & fire tube boilers with a chain grate stoker structure. Threaded pyrotechnic tubes are arranged in the drum to form a convection heating surface, while the drum and the water walls on both sides form a radiation heating surface in the furnace. Each package system is fully installed and wired before being transported to site and is electrically controlled to provide functions such as stepless speed regulation for the stoker, threshold parameter alert and interlock protection.

ZOZEN's main products include industrial boilers, power station boilers, waste heat recovery devices (HRSG), special waste heat boilers, pressure vessels and other five series with more than 400 varieties of specifications, mainly classified as: 10 ~ 220 t/h series power station boilers; SHL series bulk coal-fired Steam and hot water boilers; SZL series pipe assembly boilers; DZL series shell boilers; WNS series, SZS series of oil/gas fired boilers; YLL series of coal-fired thermal fluid heater; YYW series of fuel gas thermal fluid heater; biomass fuel boiler steam and gas combined cycle waste heat boilers, special waste heat boilers ,large regenerative boilerand so on.
