(Abstract)

Sewage sludge is a biomass resource expected to be effectively used, 80% of which has been recycled, but its energy recovery rate is only about 13% on ブックメーカー 合法 basis of organic substances (FY2010). In order to improve ブックメーカー 合法 energy recovery rate, various energy recovery promotion measures have been taken, including feed-in tariff scheme for renewable energy. On-going energy recovery is mostly utilization of digestion gases for power generation by anaerobic digestion, but a large amount of digestion gases are left unutilized, promoting development of new technologies such as utilization as urban gases by refinement. For fuel utilization in ブックメーカー 合法 existing coal-fired boilers by solid fuelization, multiple technologies, such as granulation drying, carbonization, have been developed and actual machines are running, but there are restrictions by location requirements and auxiliary fuel cost. Sludge incinerating power generation has been conventionally difficult to materialize except some large-scale facilities because of a sewage sludge property, that is, high water content. However, energy recovery from sewage sludge by sludge incinerating power generation will be enabled by recent establishment of sludge water content reduction technology and small-scale steam power generation technology.

After test operation since Jan. 2012, it was completely handed over in Jul. 2012 and has been operating successfully to date. Emphasizing ブックメーカー 合法 use of a sodium reagent as an exhaust gas treatment agent, optimum shape of ブックメーカー 合法 melting furnace, lower CO concentration by char blow rate control, and efficient energy recovery, ブックメーカー 合法 Center has established operation leading to higher economic efficiency.

Waste incineration equipment was delivered to Soma Houbu Eisei Kumiai at ブックメーカー 合法 end of November 2012. This equipment being a water spray type gas cooling facility, it has an air preheater and an air heater for prevention of white plume emission installed in ブックメーカー 合法 rear stage to recover heat, prevent white plume emission and supply hot water in ブックメーカー 合法 precincts, thus making use of waste heat. Also, a bag filter and a selective non-catalytic reduction facility are used as exhaust gas treatment equipment to eliminate harmful gases. After conducting test operation for about 5 months, a performance test satisfied predetermined incineration capacities and exhaust gas measurement values were lower than control values.

For ブックメーカー 合法 purpose of reducing ブックメーカー 合法 maintenance and operation cost of a waste incineration plant, a basic test and on-site regeneration simulation test were conducted in order to establish an on-site activity restoration method without taking out an NOx removal catalyst from a selective catalyst reduction system. In ブックメーカー 合法 on-site regeneration simulation test, it was possible to regenerate ブックメーカー 合法 catalyst by increasing ブックメーカー 合法 temperature to approx. 380℃ required for resolution of acidic ammonium sulfate; regeneration was allowed 20 times without lowering NOx removal efficiency and compression strength (assuming regeneration once a year during 20-year operation). Also, regeneration was accomplished in a short time of about 20 hours including temperature increase. SO2 gas produced at ブックメーカー 合法 time of regeneration was able to be eliminated in a slaked lime pellet filled tank, and NH3 gas was able to be eliminated by being resolved into nitrogen and water by action of ブックメーカー 合法 NOx removal catalyst without using any special chemical agent.

We have a technology to combust a chicken litter fuel and recover its energy as steam and electricity as part of effective utilization of chicken litter.Making use of this technology, we installed a chicken litter fuel combustion fluidized bed boiler power plant to NANGOKU KOUSAN CO., LTD. in Mar. 2002. And then, in March 2012, we installed ブックメーカー 合法 second power plant to ブックメーカー 合法 same company for ブックメーカー 合法 purpose of further utilization of chicken litter. ブックメーカー 合法 Report outlines ブックメーカー 合法 chicken litter fuel combustion fluidized bed boiler power plant installed this time. This plant produces steam at a rate of 35 t/h by boiler, using ブックメーカー 合法 chicken litter fuel at a rate of 13.1 t/h, and supplies steam to ブックメーカー 合法 process at a maximum rate of 16.5 t/h and generates 1,580 kW. Realizing successful combustion of ブックメーカー 合法 chicken litter fuel in a performance test, we have confirmed this plant was capable of supplying steam and power as designed. And, we have also confirmed ブックメーカー 合法 requirements of ブックメーカー 合法 exhaust gas emissions regulations were satisfied completely.

In ブックメーカー 合法 "Breakthrough by Dynamic Approach in Sewage High Technology Project (B-DASH Project)" implemented by ブックメーカー 合法 Ministry of Land, Infrastructure, Transport and Tourism, our company implemented "Full-Scale Demonstration on High-Efficiency Nitrogen Removal Technology by Fixed Bed Type Anammox Process" as a FY2012 project in collaboration with Kumamoto City and Japan Sewage Works Agency. Constructing and operating an anammox process-based nitrogen removal demonstration plant, which is designed to treat anaerobic digestion supernatant at a designed water treatment quantity of 50 m3/day, in ブックメーカー 合法 Kumamoto City Tobu Sewerage Center, this project demonstrated applicability and usefulness as a technology to remove ammonium- nitrogen contained in filtered water. ブックメーカー 合法 demonstration plant was constructed in July through November in 2012, and after subsequent test operation and acclimatization, started full-fledged operation from February 2012. Currently being under demonstrative operation, it is collecting various data for establishing an anammox process technology.

Targeting lower-moisture content sewage sludge dehydrated with advanced centrifugal dehydrator (moisture content of approx. 70%) compared with conventional dewatered sludge, and for ブックメーカー 合法 purpose of building a incineration system inhibiting production of N2O and dispensing with a dryer and auxiliary fuel, a combustion experiment was conducted using a step grate stocker furnace. As a result of ブックメーカー 合法 experiment, ブックメーカー 合法 dewatered sludge was directly poured into ブックメーカー 合法 furnace at an air ratio of 1.3 to 1.4, and ブックメーカー 合法 furnace outlet temperature of 800℃ was successfully maintained without any auxiliary fuel, achieving N2O emission of 0.3 kg-N2O/t-wet (more than 50% lower than before). At this time, ブックメーカー 合法 CO concentration at ブックメーカー 合法 furnace outlet (O2-12% equivalent) was 15 ppm or less and an ignition loss of ash was 0.3% or less. A sludge supply method used in ブックメーカー 合法 experiment was a pressure method, but there was no adherence of sludge and a supply rate fluctuation range was about ±10%, allowing stable supply. Successful incineration was also confirmed without problems in a test subjected to ±20% fluctuations of an incineration rate.

Bottom ashes were collected from some MSW incineration facilities to examine ブックメーカー 合法 chlorine content and chlorine existence form. ブックメーカー 合法 chlorine content was 0.005 to 0.015 g-Cl/g-ash and soluble chlorine was 57 to 84%. ブックメーカー 合法 smaller ブックメーカー 合法 grain size, ブックメーカー 合法 higher ブックメーカー 合法 chlorine content ; 2 mm or smaller ashes contained about 60% of total chlorine. ブックメーカー 合法 form of insoluble chlorine was conceived to be crystalline chlorine in ブックメーカー 合法 wet ashes, but no crystalline chlorine was observed in ブックメーカー 合法 dry ashes. It was confirmed that ブックメーカー 合法 chlorine content of ブックメーカー 合法 bottom ashes was reduced due to volatilization of soluble chlorine by heating ブックメーカー 合法 dry and wet ashes. When ブックメーカー 合法 dry ashes were heated at 1,000℃, however, chlorine was partly taken into amorphous, and when ブックメーカー 合法 wet ashes were heated, a complicated behavior was detected such as recrystallization of crystalline chlorine.
