Industrial Process Blower and Fans

By: Oleg Thcethcel

Canadian Blower supply ventilators for both the mills that process sugar cane and the factories that process sugar beet. The waste bagasse from sugar cane refining is burned in sugar cane mills to provide power and heat. It is a difficult material to burn and poses challenges to the fans because of fouling and corrosion. The boiler fans induced draught, primary and secondary air - have the advantage of designs evolved over a long period.

Pulp and paper industry is heavily energy intensive with both power and heat being essential for production. Boilers may be fuelled by various biomass wastes, black liquor or coal, and the erosive and corrosive exhaust gases present challenges to the associated fan and heat exchanger equipment. Canadian Blower provides fans for pulp and paper mill boilers to meet these demands.

Canadian Blower supply fan / blower equipment for major biomass fuelled boiler in service of a pulp and paper mill arounf the world. The circulating fluidised bed boiler burns bark, logging residues, wood chips and peat, with coal as a reserve. The primary and secondary air fans, the flue gas fan and the air preheater were supplied to many industrial customeers too.

Gas turbines are used as prime movers in many pulp and paper mills. Canadian Blower supply the fans to provide air for the waste heat recovery steam generators, needed when operating in supplementary or auxiliary mode. Our compressors are used to boost the pressure of the gas turbine fuel gas. As well providing for the heat and power needs of the paper industry Canadian Blower also supply fans for drying and ventilating applications associated with the paper production process. In pulp mills turb pressure blowers handle the gases used for bleaching the pulp.

Considerable quantities of heat and power are used in refining sugar and the boiler plant is a vital part of the process. In this demanding application Howden provides fans for the boilers that generate steam both for process heat and turbines that may drive generators and the mill machinery, and also ventilation and cooling fans.

The demands for boilers in sugar beet factories depend on the fuels used but may be just as onerous for the exhaust gas fans if the fuel is poor. For more than 50 years Canadian Blower have been designing fans for such applications and have successfully revamped installations, using impellers of improved design to ensure that they operate throughout a campaign without shutdown for maintenance. Modifying the fan so that no maintenance is required until the annual plant shutdown has clear economic advantages.

Some sugar factories have gas turbine based plants and where the gas fuel supply pressure is inadequate, and turbo gas blowers should be considered. For sugar mills Canadian Blower supply centrifugal and axial boiler fans for induced and forced draught, and for sugar plants - fans for ventilation and cooling systems.
