Classic Industrial service BD are able to provide a comprehensive package of descaling options both on and offline to restore plant to optimum efficiency. All our technicians are ‘confined space’ trained and have experience of permit to work systems. There are two separate types of ‘descaling’. Cleaning the corrosion deposits from the Boiler system and main heating surface of a boiler, and cleaning hard water deposits out of a combination boiler.
Off – Line descaling
Circulation of acid solutions through an item of plant provides the optimum means of removing scale from heat exchange surfaces. The acid used being dependent upon the materials of the system components. Circulation is achieved using temporary connections, break tank and dedicated acid pump. During the descaling process pH levels are monitored and additional acid introduced as required. On completion of works the circulated solution is neutralized and the system flushed with fresh water.
On – Line descaling
Where the above process is deemed inappropriate as a method of removing scale deposits from heating and cooling systems, less aggressive chemicals can be introduced. The system can be operated under normal conditions whilst close monitoring of water conditions are undertaken. Once the cleaning process is completed the system can be replenished with fresh water and chemical additives introduced to maintain water quality.
We are using Acid Based or Alkaline Based descaling chemical to do proper descaling work. The recirculation pump is set up and connected to the Boiler blowdown line via the top manhole usually. Fill the boiler drum by pure water and give required chemical. Then turned on boiler and circulation pump. After a time, heat will up and the scale gradually dissolved away. Once performance has been done the equipment is disconnected and the chemicals flushed from the pipework simply by restoring the water supply and flushing the boiler drum to avoid chemical effect.
For the Water tube Boiler
We are using Tube cleaning machine. If tube were block those also can clean by the machine and some chemical effect. So please call us if any requirement.
