Tenders Are Invited For Measuring And Control Equipment - 27/25 Delivery Of Exhaust Gas Measuring System in Hungary

Work Detail

Measuring And Control Equipment - 27/25 Delivery Of Exhaust Gas Measuring System. The Following Components Of Flue Gas Emitted By The Energy Generating Units Of Mvm Mátra Energia Zrt. (Ak) Are Measured By Official Order. We Plan To Replace The Flue Gas Measuring System That Performs These Measurements. Ak Has 1 220Mw And 2 232Mw Installed Coal-Fired Power Generation Units, As Well As 2 33Mw Natural Gas-Fired Units. Coal-Fired Units Consist Of Boilers, Turbo-Generator Sets, Cooling Systems And Flue Gas Cleaning Equipment. The Daily Coal Consumption Of The Power Plant Is 7-10 Thousand Tons. All Three Boilers Are Coal Pulverized, Two-Pass, Membrane-Walled, Semi-Outdoor Design. When Burning Lignite, The Temperature Of The Firebox Is 1000-1100Oc. The Air Required For Combustion Is Provided By Fans, And The Boiler Has A Suction Firebox. In Addition To Lignite, Alternative Fuel Mixed With Biomass (Srf) And Biomass Are Burned In The Boilers. Flue Gas Cleaning, Compliance With Emission Limit Values: Sncr Technology: To Reduce The Amount Of Nox Generated, As The First Phase Of Flue Gas Cleaning, The Iii-V. Sncr System Operates On Blocks No. Through The Method Of Selective Non-Catalytic Reduction, The Process Reduces The Amount Of Nitrogen Oxide In The Flue Gas With Urea Reducing Agent. Dust Separation, Desulfurization: The Dust Separation Of The Flue Gas Leaving The Boilers Is Carried Out By Electrostatic Dust Separators, Which Separate 99.5-99.7% Of The Ash. Further Cleaning Of The Dust-Free Flue Gas Is Carried Out By Flue Gas Desulfurization Equipment. Limestone Flour Is Used As An Additive For Desulphurization, Which Is Introduced In The Form Of A Suspension Into The Countercurrent Washing Tower. As A Result Of The Washing Solution Sprayed On Several Levels, The Flue Gas Cools Down, And As A Result Of The Chemical Reactions, The Limestone Binds The Sulfur Dioxide Gas, While It Oxidizes Into Calcium Sulfate, I.E. Gypsum. The Average Ph Value Of The Absorbent Suspension Is ~5.2Ph. The Cleaned Flue Gas Exits The Desulfurizer At The Head Of The Washing Tower. The Water Droplets From The Purified Flue Gas Leaving The Top Of The Absorbers Are Separated By Two-Layer Droplet Separators Installed On The Top Of The Absorbers. The Average Temperature Of The Outgoing, Saturated Flue Gas Is ~62Oc At The Exit Emission Flue Gas Measurement Points. The Cleaned Flue Gases From The Desulfurizers Go Outside Through The Point Sources P2 And P3. The Flue Gas Desulfurizers Are The Iv. And Were Placed In Heller-Rogó System Cooling Towers Belonging To Block V, Their Emission Height: 116M. Task Definition: The Exit Emission Flue Gas Measurements On The Current Absorbers Are Outdated, Their Repair And Maintenance Are Impossible, And Their Supply Of Spare Parts Has Ceased. Taking Into Account Our Stricter Uniform Environmental Use Permit (Ekhe), A New, Stable Measuring System That Meets The Legal Requirements Will Be Replaced On Both Absorbers. 2 Identical Measuring Systems. Gas Concentration Measurement: A Hot Extractive Ftir Gas Analyzer, A Complete, Uniform, Measuring System Built With A Native Measuring Device Was Defined As The Measurement Principle Of The New Exhaust Emission Flue Gas Measuring System To Be Installed. The Measurement System Is A Sample
