10 Replacement Plus products superheater for standard fuels The superheater has come to the end of its life time? Looking for a highly reliable replacement product with excellent welding and material qualities? The ANDRITZ replacement superheater is perfectly adapted to its intended purpose. A wide range of materials ensure the optimum balance between resistance to corrosion/erosion and material costs. Frequent quality checks in the workshops ensure excellent fabrication and welding quality. 10

11 Replacement Plus products superheater for waste fuels Very high chlorine content in fuel? The ANDRITZ replacement superheater for waste fuels goes the extra mile! Top-quality materials with high chromium content ensure excellent resistance to corrosion and erosion caused by aggressive fuels. Cladding with Inconel 625 or 686 are possible options, and we also offer well-proven spray coating. 11

12 Replacement Plus products superheater RC Plus Tube supports are often bottlenecks? ANDRITZ has developed a special support with perfect cooling and excellent heating surface alignment. If there are changes in fuel used, the existing gradient might not be sufficient, which will result in increased slagging. ANDRITZ offers a special hybrid design with double the gradient and identical heating surface area. 12

13 Replacement Plus products additional CC heating surfaces The combustion chamber (CC) outlet temperature is too high because you have to change the fuel to higher LHV or run continuously at higher load? Is erosion an issue in the second pass? Running at higher load increases the volume of flue gas, which also has a lower density due to the higher CC outlet temperature. The resulting significant increase in flue gas velocities can cause erosion. ANDRITZ offers wing wall heating surfaces with: high erosion resistance low manufacturing costs compact boiler space requirements easy maintenance high heat transfer rate workshop coating as an option 13

14 Replacement Plus products heating surface protection The dust load is very high and the ash very sticky? Heating surfaces need to be cleaned more often? ANDRITZ heating surface protection systems (= tailor-made, cast protection tubes) improve the equipment lifetime. INCONEL cladding is available for the first rows and for the supporting tubes. 14

15 Replacement Plus products BFB nozzle grid for waste fuels Particularly critical fuels with very high levels of impurities, especially wires and nails? ANDRITZ has developed T-nozzles to enable longer operating times between shutdowns. 15

16 Replacement Plus products CFB nozzle grid for standard fuels ANDRITZ fluidization module for CFB boilers benefits: Fuel integration is improved in the entire bed area, leading to controlled and homogeneous combustion. As a result of improved primary air distribution, the average bed temperature is distributed more evenly. The fluidization gas volume is constant over the load range. The open design significantly reduces blockages caused by coarse inert materials. 16

17 s Replacement Plus products CFB nozzle grid for waste fuels Large impurities in the fuel that destroy your conventional open nozzle grid? ANDRITZ offers a concept specially designed for waste fuels and fuels with heavy impurities to extend the nozzle lifetime and avoid any cracks in the support structure. 17

18 Replacement Plus products CC cross-over tube protection The cross-over area in the combustion chamber from refractory to membrane wall is always critical tube erosion is a well-known problem. ANDRITZ offers a replacement solution without involving the pressure part. Creating a balcony on top of the refractory gives the sand a platform to pile up on. This sand pile protects the critical, lower part of the tubes. 18

19 Replacement Plus products pneumatic fuel feeding systems BFB: Problems with carry-over and bed temperatures that are too low although your fuel heating value is ok? You want to use an additional fuel? CFB: Problems with higher temperatures in the cyclone compared to the CC and extensive fouling at the convective pass? ANDRITZ offers a pneumatic fuel feeding system that pushes the fuel into the high-density bed and generates perfect combustion in the CC. Low calorific fuels and very low density fuels can also be burned efficiently. As only the fuel spouts have to be installed at the boiler and the feeding lines in the boiler house, this system can be installed easily afterwards. Conveying air 19

20 Replacement Plus products advanced fuel control Fuel is fluffy and tends to compact? Boiler flue gas pressure is fluctuating and emissions are difficult to stabilize? ANDRITZ offers an advanced fuel control system that continuously recalculates the heating value of the fuel and creates a feed forward signal for the fuel controller. In addition, the mass flow through the dosing screws can be measured radioactively to stabilize the fuel heat input when heating values fluctuate. 20

21 Replacement Plus products advanced corrosion reduction Chlorine corrosion is rapidly destroying your superheater, but you have no means of changing the chlorine content in the fuel? Without ChlorOut: chloride 25%, fouling rate 21 g/m2/h ANDRITZ offers a new licensed concept together with its partner ChlorOut AB to remove the chlorine from the deposits at the heating surfaces and reduce chlorineinduced corrosion. Ammonium sulfate is added in the combustion chamber and. decomposes to NH 3,SO 3, and water after being injected: (NH4) 2 SO 4 2 NH 3 + SO 3 + H 2 O SO 3 reacts with alkali chlorides to form alkali sulfates and HCl (2 KCl + SO 3 + H 2 O K 2 SO HCl) Ammonium reacts with NOx to act as SNCR agent (4 NH NO + O 2 4 N H 2 O) With ChlorOut: chloride <0.2%, fouling rate 6 g/m2/h 21

22 Replacement Plus products advanced SNCR systems High nitrogen content in fuel? Air staging is not enough to reach the requested NOx emission limit? ANDRITZ offers SNCR systems for BFB and CFB boilers with high efficiency. Modern systems with pyrometer probes and two-level design enable good part-load operation as long as the flue gas temperature is above 850 C and combustion is completed at the injection point..

23 Upgrades 1 st step: Concept development Boiler performance not coming up to your expectations: What s the most cost-effective solution? Need a first idea of how it could work and what the rough investment budget would be? ANDRITZ provides individual analytical expertise for following up on BFB- and CFB- related tasks: Load increase Load decrease Fuel change Emissions reduction Waste heat recovery Availability increase 23

24 Upgrades 2 nd step: Feasibility study Boiler performance not coming up to your expectations: What s the most cost-effective solution? How can the upgrade be implemented (details)? What investment budget do you need? ANDRITZ provides individual analytical expertise for all engineering and operational aspects of BFB and CFB boilers: 1) We start with a detailed investigation of the existing plant and also collect operating data. 2) Using this information, we then perform a thermodynamic simulation of the boiler. 3) On the basis of this calculation, technical solutions are developed and the most economical one is selected. 4) Finally, the investment budget and amortization period are calculated for the recommended modifications. 24

25 Upgrades 3 rd step: Realization Fuel and firing enhancements Extended range of fuels Customized application and distribution of air Capacity increase Load increase by modifying pressure parts, fuel and ash handling systems, air supply, and flue gas cleaning Emissions reduction Tailor-made emissions reduction (NOx, SOx, dust) to meet future emission limits with existing power boilers. Increased availability and longer lifetime New design of pressure part and fluidization module New, reliable fuel and ash handling equipment 25 Waste heat recovery Additional heating surfaces to generate low-temperature heat for external and internal use
