Services and Solutions
Plexodyne is a provider of Fireside Boiler Cleaning technology, designed to remove inhibiting slag in boilers,
on-line without the need to make any load adjustments.
The technology involves introducing a chemical method for reducing and inhibiting slag
and clinker in boilers. Forced outages due to slagging are no longer required.
Plexodyne PD96X is a proprietary blend of Alkali Nitrates and Catalysts in an aqueous solution.
The chemical is injected directly into the firebox. PD96X then vaporizes and is carried through the
system by the flue gases laying down on all the heat transfer surfaces. The chemical reacts with the main
fouling and bonding agents, making deposits soft, dry and friable. This reduces thermal barriers,
Improving heat transfer in the system.
Fouling no longer binds to the tubes and falls off
or is carried away by the flue gases. PD96X is designed to prevent fireside deposits that
lead to inefficiency maintaining clean heat transfer surfaces for the period of the Production
campaign, and is considered to be of great benefit. It is with this in mind that we developed our product.
Availability of maximum performance can be achievable with the use of PD96X.
Our product reacts with fireside deposits produced from the combustion of the following fuels:
Coal-Derived Synthesis Gas
Waste/Other Coal (incl. anthracite culm, bituminous gob, fine coal, lignite waste, waste coal)
Distillate Fuel Oil (including diesel, No. 1, No. 2, and No. 4 fuel oils)
Residual Fuel Oil (incl. Nos. 5 & 6 fuel oils, and bunker C fuel oil)
Synthesis Gas from Petroleum Coke
Waste/Other Oil (including crude oil, liquid butane, liquid propane, naphtha, oil waste, re-refined motor oil, sludge oil, tar oil, or other petroleum-based liquid wastes)
Liquid Renewable (Biomass) Fuels
Wood Waste Liquids excluding Black Liquor (including red liquor, sludge wood, spent sulfite liquor, and other wood-based liquids)
Wood and Wood Waste Solids (incl. paper pellets, railroad ties, utility poles, wood chips, bark, and wood waste solids)
Simple and Low Cost
Plexodyne engineers will assist on site with the installation of the PD96X Fireside Cleaning product.
Pumps and piping are required to be erected in order for the lance to be loaded with the chemicals,
ready for injection. The PD96X product is non-toxic and easy to handle.
Plexodyne engineers will also assist on-site with full user training.
The use of Plexodyne will achieve the following:
Increased Boiler Efficiency
Increases the boiler thermal efficiency by reducing insulating slag on the boiler tubes and improving boiler draft
Boiler Draft Improvement
Reduced slag and clinkers in the boiler improves the draft which leads to lower fan power consumption.
Reduced Maintenance and Downtime
On-line cleaning actively controls slag and reduces clinker build-up in the boiler forced shutdowns due to slagging are eliminated. Additionally, the thermal conductivity is improvementsd and it reduces thermal hot spots and improves the boiler tube life.
Improved thermal energy transfer means that less fuel is needed for the same output, a more efficient plant results in lower overall emissions.
Reduces fuel consumption
Improvements in plant efficiency reduces fuel consumption.
