First, the low nitrogen gas process of boiler water introduce low nitrogen gas boiler is upgraded on the basis of the ordinary furnace, it is more than an ordinary stove biggest advantage is that the emission of nitrogen oxides. A low nitrogen gas boiler is divided into two: one is nitrogen oxide emissions below 80 mg; the other is a nitrogen oxide emissions below 30 mg. Of course, if you want to achieve low nitrogen emissions, it must be met is to use low-nitrogen burners. The most outstanding feature is the low nitrogen gas boiler NOx emissions low. High emission standards for areas such as Beijing, Zhengzhou. Unduly limit the nitrogen oxide emissions to be 30 mg or less, it is necessary to select a low nitrogen gas boiler.
In the Kraft Recovery Process (liquor loop), white liquor is used to cook wood chips and yields pulp and weak black liquor (separated by washing in multiple steps). This weak black liquor is concentrated in evaporators (another large steam user) to produce a fuel the recovery process of boiler water(s) can use to produce power and process steam. The inorganic portions fall into the smelt tank and are dissolved to produce green liquor. This green liquor is then re-causticized to produce white liquor (hence the term liquor loop). This recovery loop aids in saving money by reducing waste of cooking chemicals, producing steam, and producing power.Imagine if fresh cooking chemicals had to be purchased and used exclusively to cook the chips!The recovery loop, with the recovery boiler playing a key role, makes paper mill operations economical.
Which fuel hot water process of boiler water For now, the gap between domestic hot water boiler fuel suppliers, power analysis, and each has its own strengths oil hot water boilers case. I do not know if you judge oil hot water boiler is really a problem of what professional standards. Now normally want to choose the right people for the fuel hot water boiler units, listed some of the following criteria need to know: First, hot water boiler fuel consumption indicators Second, oil hot water boiler steam out time three or oil hot water boiler the provision power four, on the style of some of the standard fuel hot water boiler, hot water boiler fuel is enough to get absolutely inappropriate common, most also need to think twice inappropriate, from some of these criteria, you should see 1 oil-fired hot water boiler efficiency is really a problem, of course, hot water boiler fuel election day for all of us to find the most units, the price of oil hot water boiler is the most important.
