Unique three chamber design reduces emissions
We have invented a three chamber incinerator design that is unique on the market. This design achieves a longer retention time than conventional single chamber designs, and by extending the time that the waste is subjected to 850-950°C lower dioxins (SOx and NOx) emissions are achieved, well below the IMO emission standards.
Extra combustion air is injected into the after-burning chambers, ensuring destruction of all unburned particles. This extra flow prevents any unburned particles or flames from escaping the incinerator and entering the flue gas funnel.
All chambers are protected by high temperature castable lining designed to withstand temperatures of up to 1600°C.
Burning sludge oil with up to 50% water content
The IMO standard for sludge oil states that there is 20% water in the sludge oil. But often sludge oil contains more water than this.
Many ship owners use an extra tank to settle the water out, but this is both time consuming for the crew and takes up more space in the engine room. Some heat up the sludge oil tank to 100°C to evaporate the water and exhaust it to the atmosphere, but evaporating requires a lot of energy and is also time consuming.
We recommend a simple, automatic one tank system. By not using a settling tank the crew will save time. And burning high water contents makes it possible to burn higher volumes of sludge oil, due to the cooling effect of the water.
Furthermore, there is a positive environmental impact of burning sludge oil with as much water as possible as it reduces NOx in the emissions
Sludge oil mixing tank
By not using a settling tank the crew will save time, not needing to settle water out.
Sludge oil mixing tanks are delivered with a circulation pump and a mill pump for agitation and comminution of the tank contents. This makes it possible to burn oil sludge with up to 50% water content, without adding additional diesel oil to the burners or having to drain the tanks.
The sludge oil mixing tanks are available with heating by steam, electricity or thermal oil and in the following sizes:
500 ltr., 1200 ltr., 2600ltr. and 4000 ltr.
The unheated sludge oil mixing tanks are available in the following sizes:
1000 ltr. and 1800 ltr.
Our incinerators operate without the installation of a flue gas fan in the exhaust pipe (based upon a max counter pressure of 60 mm WG), saving costs of operation and maintenance on what has proven to be the most time consuming trouble point in an incinerator installation, due to imbalance of the impeller caused by soot from the hot exhaust gasses.
Atlas designed sludge burner
The Sludge burner is of the air atomising type with no moving parts. It is via the sludge circulating pipe is equipped with a “self cleaning strainer” preventing any kind of blocking. This ensures that no maintenance is required and it reduced spare parts compared to rotary cup burners.
