A number of production activities produce industrial waste in the form of liquids and gases. Environmental awareness around the world is gaining traction and tighter regulations and laws governing this waste are increasing. We help support this by offering advanced combustion technology. In addition, we continue to develop new technology in order to further environmental performance.
We integrated technology from the English company Urquhart Engineering Company during the 1950s, and this combustion chamber is the result of over 60 years of improvements and development.
This combustor adopts multiple nozzles from three different directions to blow in combustion air, producing a short flame and generating complete combustion inside the combustion chamber.
In addition, submerged incinerator are subject to internal pressure fluctuations; however, this combustor achieve stable combustion without flame failure caused by these types of variable loads.
In order to properly decompose the waste liquid inside the furnace, the waste liquid must be atomized and sprayed into the furnace. If the size of the waste liquid droplets is too big, the high temperature oxidative decomposition will not reach enough in the furnace and some unburned organic may can leave unburned matter.
As a result, the most appropriate spray must be selected based on the volume, makeup and characteristics of the liquid waste. We determine an internal standard that the liquid drop size is less than 150 µ (average size).
We developed our own unique seal mechanism to facilitate maintenance or replacement of the sprayer as needed during equipment operation and to reduce the outflow of high temperature gases when the sprayer is removed. As with this mechanism, there is no need to stop incinerator operation when there are problems with the sprayer, making it possible to continue incinerator operation.
Exhaust gas cooling
The high temperature gases emitting from the furnace pass through the sealing water in the quencher and are effectively humidified and cooled momentarily, dropping the temperature down close to 90 degrees.
The molten salt that develops inside the furnace flows down the furnace walls, passes through the dip tube and dissolves in the quencher fluid (seal fluid). The dip tube uses a wetted-wall structure to prevent burnout problems. In the equipment design, some points to keep in mind include protecting and preventing metal corrosion, thermal strain and salt adhesion.
The water is injected into the throat of the venture scrubber. The solid particles (inorganic salt fumes) in the high speed air stream collide with the water drops, causing inertial impaction and effectively catching the fine particles or dust.
