Vatten injektion nox

Att injicera vatten i en This system injects demineralized water into the combustor through the fuel nozzles to regulate the combustor flame temperature and lower NOx emissions. Significantly reduced NOx emissions down to 25 ppm (gas fuel) or 42 ppm (liquid fuel). 1 Ovanför den reducerande zonen görs Water Injection technology, whereby water is introduced into the combustion chamber, is also becoming an important means of NO x reduction through increased efficiency in the overall combustion process. Alternatively, the water (e.g. 10 to 50%) is emulsified into the fuel oil before the injection and combustion. 2 Med hjälp av vår A new high pressure water injection system designed to reduce nitrogen oxide (NOX) emissions from a peaking power plant in New York requires water with an ultra-low silica concentration. 3 Intelligent börvärdeskontroll · Adaptiv The NOx reduction effect with the introduction of water (or vapour) is achieved by reducing the local maximum combustion temperatures in the combustion chamber and also by reducing the concentration of oxygen by the addition of inert media with high specific heat (vapour). 4 SNCR renar kväveoxider (NO och NO2) The rate of Nox emissions controlled is directly influenced by the quantity of water (water-to-fuel ratio) injected into the gas turbine combustor. 5 Under torkningen avdunstar vatteninnehållet It is revealed a significant reduction of NOx with both techniques compared to conventional engine operation. The reduction is higher when using water-fuel emulsion compared to water injection in the intake manifold for the same water percentage. 6 Liquid water or steam injection is a technique that has been used for years to reduce NOx primarily by reducing the flame temperature which reduces thermal NOx. There is also evidence to suggest it reduces NOx by modifying the flame chemistry. 7 Abstract. Liquid water or steam injection is a technique that has been used for years to reduce NOx primarily by reducing the flame temperature which reduces thermal NOx. There is also evidence to. 8 View history. Tools. Selective catalytic reduction (SCR) means of converting nitrogen oxides, also referred to as NO. x with the aid of a catalyst into diatomic nitrogen (N. 2), and water (H. 2O). A reductant, typically anhydrous ammonia (NH. 3), aqueous ammonia (NH. 4OH), or a urea (CO (NH. 9 Mängden NO X (räknat som NO 2) är alltså uppmätt NO i rökgasen omräknat till NO 2 med ett påslag för mätt eller antagen mängd NO 2. Korrektion görs för hur utspädd rökgasen är. Den energi som används under mätperioden beräknas utgående från bränsleförbrukning och bränslets energiinnehåll eller utifrån rökgasanalysen. 10
