3.Two types of high pressure water tube boilers are specified, flex tube and D-type. The two boiler types are significantly different, and only one of the two types should typically be specified if all new boilers in a given project are similar. 4.Flex tube boilers: a)Primarily for non-critical service firing gas fuel and with stable steam demands.Learn More
The agent breaks down the NO x in the exhaust gases into water and atmospheric nitrogen (N 2 ). While NSCR can reduce boiler NO x emissions by up to 70%, it is very difficult to apply to industrial boilers that modulate or cycle frequently because to perform properly, the agent must be introduced at a specific flue gas temperature.Learn More
Chelating agents offer an opportunity for supplying better results in boiler water treatment (i.e., cleaner boilers). The important key to success is to use the same care in selecting, applying, and controlling the treatment program. Chelating programs are another variation of water treatment. The word chelate derives from the Greek word chele,Learn More
