The boiler adopts an environmentally friendly combustion method - full premixed combustion, and the gas and air are precisely adjusted and premixed in advance to ensure more complete combustion.
The boiler adopts a double-drum longitudinal "D" type arrangement structure; water, steam or steam-water mixture flows in the pipe; flame burns and flue gas flows outside the pipe, forming extremely fast steam-water.

Accepta 2061 is a high-performance DEHA based oxygen scavenger scientifically formulated to deliver outstanding protection from oxygen corrosion together with effective feed water and boiler system passivation. Accepta 2061 can also be used as a replacement for hydrazine. Accepta 2061 may be used in boilers at up to 125 bar, eliminating most of
2/5/2010 · Similarly for amine dosing in boiler based on PH. 1. Reaction of hydrazine NH2NH2+O2-->2H2O+N2 indicates dosing of 1 gr NH2NH2 / gr O2. In practice 1.5 to 2.0 gr NH2NH2 / gr O2 is applied, probably because hydrazine protects metal from corrosion by converting Fe2O3 to Fe3O4. Injection is into deaerator (or close to it).

26/6/2017 · Assume boiler operates at 10 cycles of concentration, and the residual boiler water alkalinity, M, is 250 ppm. To develop this alkalinity, we need 25 ppm soda ash (as CaCO 3 ) in the feedwater (250 ppm boiler alkalinity divided by 10 concentrations), over and above the amount required to neutralize non-carbonate hardness in the feedwater.
5/7/1992 · The boiler parts are filled with DM water containing 300-500 ppm hydrazine and a nitrogen atmosphere is maintained above the water level. Hydrazine concentration is monitored periodically and maintained at the required concentration by topping up when needed.
