NCG (NON CONDENSIBLE GASES)

NCG Burning in Recovery Boilers This time i will explain about Non Condensible Gases or NCG in Power plant boiler.after yesterday I was talking about "How does a power plant boiler work?" NCG = Non Condensible Gases NCG are: the non-condensable gas, this gas has a very distinctive odor karesteristik. This odor is caused by a mixture of sulfur into TRS (Total Reduced Sulfur) Categories A.Composition and NCG NCG content include: Hydrogen sulfide (H2S) Mercaptan (CH3SH) Dimethyl sulfide (CH3) 2S Dimethyl disulfide (CH3) 2S2 Ethanol (C2H5OH) NCG gases are divided into two categories, namely: LVHC = Low Volume High Cocentration High Volume Low HVLC = Cocentration B. Sources of NCG NCG is the fuel in the RECOVERY BOILER sourced from: A. LVHC: a. Strippe gas b. Gas from the evaporator plan (VE) c. Faul VE Condensate Tank d. Digester plan (PULP MAKING) 2. HVLC: a. WBL Gas Tanks & Tank HBL 3 & VE b. Gas & PULP MAKING Design Data LVHC RB-1 Design Data Stripper Gas: Flow = 1550 Nm ³ / h Temp = 80 ° C Moisture = 48% Volume Gases from Evaporator Flow = 680 Nm ³ / h Temp = 50 ° C Moisture = 13% Volume Digester gas form Flow = 335 Nm ³ / h Temp = 90 ° C Moisture = 71%.see also previous article "Vacuum evaporator(VE)
