Measurement of Oxygen Concentration in Package Boiler Flue

The ZR22G/402G zirconia oxygen analyzer can also be used in bagasse- or bark-fired boilers under general conditions. Use of VVVF control can yield further reductions in fuel and electric power consumption. This can be done by combining the zirconia oxygen analyzer with a VVVF inverter and a programmable controller.

SPONTANEOUS COMBUSTION OF STORED SUGAR CANE BAGASSE

24 Spontaneous combustion of stored sugar cane bagasse bre residue resulting from the process of extracting sugar from the shredded cane is known as bagasse. In other countries the bagasse has been used as a fuel in the factory boilers for co-generation of steam and electricity. This obviously reduces costs and so improves competitiveness.
