BOILER 4 AFTER 6 MONTHS OPERATION WITH SAPEC TREATMENT

BOILER WITHOUT SOOT-BLOWERS

Boiler tubes after 12 months with SAPEC and without Soot Blowers

Boiler plant : 2 0ff 16 t/hr John Thompson Boilers

RESULTS FROM USING SAPEC

12 months between Cleaning. Extended operating period between cleans by 100%.

Since the introduction of SAPEC 3 years ago the Coal cost per tonne of product produced has reduced by 35% per tonne of product.

RSA PAPER MILL

Demonstration carried out on 2 identical boilers.

Boiler-plant: 2 identical 26t/hr John Thompson Water-tube traveling grate boilers. Boiler No 1 was untreated and Boiler No 2 was treated with SAPEC

RESULTS

	Boiler No 1 had to be taken of line for cleaning after only 33 days
	Boiler No 2(SAPEC) ran 123 Days without problems.
	Improved Combustion: Carbon Monoxide reduced by 33%, Carbon in Ash for Boiler No 2 is approximately 20% lower than boiler No 1.
	Higher Steam/Coal ratio; The Steam/Coal ratio for boiler No 2, 7.7:1 (highest recorded 7.8015:1) Normal Steam/Coal Ratio = 7.4:1
	Reduced Particulate Emissions: Boilers 1 and 2 share the same stack and therefore the positive effect of SAPEC on particulate emissions would be diluted. Even so particulate emission decreased by 40ppm and are now constantly in the region of 65 milligrams particulate per cubic metre of stack gas. The reduction in particulate emission will reduce wear on the ID fans and the current that they consume.
	Boiler Cleaning Reduced.
	After 33 days of trial the whole Boiler plant went onto SAPEC system.

Boiler No 1 ( NO SAPEC) After 33 days

Boiler No 2(SAPEC) after 30 days
