WNS horizontal gas fired boiler is horizontal internal combustion gas boiler, through the combustion of the fuel,the boiler water is heated to a certain temperature and output hot water and steam, belonging to the large heat energy equipment.
Today's manufacturers, boiler water normal nitrate analysis making equipment, the first thing to pay attention to, is now equipment automatic control system, automatic control only, we can improve the efficiency of which played a performance of them. The second is such a device, but also the need to ensure a certain degree of security, which is critical, so once in the event of any danger, but also the need for automatic protection, which can enhance the safety of the boiler equipment.
How a 20 ton coal fired boiler working is a main question what clients caring about, here, I will talking about how a coal boiler working during production in briefly below:[email protected]

2006-8-25·1. Alkalinity: This is the sum of components (mainly bicarbonate, carbonate, and hydroxide) in the water that tend to elevate the pH of the water above 4.5.These factors are characteristic of the source of water and the natural processes taking place at any given time. Alkalinity represents the buffering capacity of water and its ability to resist a change in pH.Free Chat
Fish and aquatic insects can be affected indirectly by increased nitrate concentrations in the water. Basically, any excess nitrate in the water is a source of fertilizer for aquatic plants and algae. In many cases, the amount of nitrate in the water is what limits how much plants and algae can grow. If there is an excess level of nitratesFree Chat
