Embodiment 1
[0059] Initially, the treatment composition (F-500) was diluted to a 3% V / V solution in water. Combustion starts in the chamber. The treatment composition is introduced into the flue immediately from the outlet of the chimney. There are 2-4 knots of wind blowing in. The diluted treatment composition spray mixes well with the smoke as it exits the chimney. In fact as soon as the solution was introduced the smoke rapidly changed from a rich black to a less dense light gray / white. Visual acuity is improved by at least 50% through the color change of the smoke. It should be noted that the treatment composition is delivered to the smoke from a location remote from the combustion.
Embodiment 2
[0061] The same procedure as in Example 1 was carried out, except that a 6% diluted treatment composition was used. This leads to similar or identical results to Example 1. There was no noticeable difference in performance between the 3% and 6% solutions, possibly because the amount of smoke was within the handling capabilities of the smaller 3% solution. It is contemplated that greater exhaust smoke concentrations will require larger quantities and / or higher concentrations of treatment fluid.
[0062] Without binding itself to one view, applicants believe that the color change may indicate that hydrocarbon molecules and particulate matter in the smoke are undergoing microcellular encapsulation, rendering them inert and trapped. It was further shown that at least some of the sulfur contained in smoke is also subject to microcellular encapsulation. It is believed that the method may result in one or more of particulate matter, volatile organic compounds, carbon dioxide, carbo...
Embodiment 3
[0066] 300ml of diesel fuel was placed in the crucible inside the stainless steel burner and ignited. The obtained smoke was poured into a 125mm×1000mm stainless steel chimney. The total height of the burner / chimney elements is 1700mm and the sampling port in the chimney is located 1200mm above the crucible and is well within the plume.
[0067] At the upper position adjacent to the sampling port, the smoke exits the chimney through a 30mm duct and reinforced hose which draws the exhaust into an 80mm diameter chimney and into the cleaning chamber. A 12 volt induction fan is powered using a three-stage variable speed switch and a rheostat. This combination provides full control over fan speed and ensures continuous forward flow of exhaust throughout the unit.
[0068] The cleaning chamber is a 90mm x 1500mm tube equipped with three micro spray nozzles. A 3% solution of cleaning fluid was supplied to these nozzles by a pressure pump. A 12-volt pressure pump is energized usin...
