EWATER technology: Solutions to limit heat waste at the boiler

Currently, boilers are being widely used in many production areas. However, during use, many problems have arisen due to scale deposits in the boiler water pipes reducing the heat transfer capacity of the boiler, causing waste of heat, reducing equipment life and causing unsafety for operators.

According to Ewater Engineering research, scale and algae clinging to boiler tubes can reduce the furnace’s heat transfer capacity, wasting 5 – 30% of the heat energy, and also causing pipe erosion, resulting in expenses for treating hazardous wastes that pollute the environment for enterprises.

To solve this problem, Ewater Engineering has researched and released EWATER anti-scale device. This device is able to actively absorb ions in water before reaching saturation, so this ion has no chance of adhesion to the heat exchanger.

Ewater anti-scale device (composed of 1 transmitter and signal line installed on the pipe), applying Faraday’s law to create inductive electromagnetic field in the tube (frequency varies continuously from 2, 2-38kHz) provides energy to ionize water, causing substances that cause scale, rust (Ca, Mg, Si, Fe, Mn) lose their ability to adhere on pipes. At the same time, this electromagnetic field provides the power to separate water molecules, freeing electrons from hydrogen to precipitate deposits and neutralize charge. Therefore, these substances will no longer adhere to the surface of the pipe, but easily drift downstream.

In addition, at the reaction device, a part of H2O will be separated into Hydroxyl and Oxygen freely, these are two components with high oxidation power, algae, microorganisms in water will be inhibited and not discharged.

According to Ewater Engineering’s practical test, the amount of scale and rust can be reduced by up to 50% after 60 days, and there is no algae remaining on the equipment pipe. At the same time, businesses also save on maintenance costs and reduce waste of corresponding heat at the boiler.

Besides, the handling of scale by EWATER technology also has many advantages compared to chemical treatment. First of all, for the chemical treatment process, the chemical erosion of equipment is inevitable, the cost per treatment is also quite high (about over 1 million VND for one treatment). , and repeated processing also shortens device life. For EWATER, the equipment has a negligible operating cost (only about VND 500,000 / year for a 15-ton / hour boiler or VND 190,000 / year for a 3-ton / hour), just checking the status work, maintenance-free.

Moreover, the device can actively change the resonant frequency depending on the water quality, water treatment with hardness above 200mg / l (designed specifically) and meet for many types of boilers with a capacity. from 100kg – 30 tons and most importantly, magnetic treatment will not affect the life of the device. With the above advantages, EWATER has been widely applied to many industries such as garment, textile, dyeing, food processing, etc.
