Shiroishi incineration plant was completed and delivered to City of Sapporo from our company in November 2002. This report is described about the features.
This plant has incineration facility including three units of 300ton/day stoker type incinerator and ash melting facility including two units of 70 ton/day plasma type ash melting furnace. Theses two facilities are laid our in separate buildings. The municipal waste treating capacity of the plant is 900ton/day.
The incineration facility generate electric power with higher efficiency using steam of higher pressure and temperature than the condition generally used. This electric power is used by the energy of plasma ash melting furnace.
Toyama incineration plant with plasma type ash melting furnace was compleated in December 2002 and started to operate. This plant is performed resorce recovery. Heat energy generated from incinerator is recovered and used activity.
Also, Ash and fly ash is disposed using plasma type ash melting furnace. This report is described about the features.
Utilization of biomass as fuel is becoming very active, with the support of various government assistance programs since it has acquired a legal status as a source of new energy. This trend is in the background as we delivered to the city of Nosiro, Akita a power generating plant equipped with a travelling stoker for burning wood biomass.
In order to utilize wood biomass from the forest effectively, it is necessary to: gather the resource that exists over large areas in an efficient manner; acquire stable users of the energy and develop a competent energy recovery system tailored for the needs of the customers. In other words, a total system including the software and the hardware must be established that can perform such tasks.
Nosiro biomass generator has the cooperative (Nosiro Forestry Resource Utilization Cooperative) as the owner-operator that sells electricity and steam. It has solved the related problems, and is operating successfully.
While being While being observed by effective use of biomass fuel from the view of environmental preservation in recent years, Takuma has supplied many boilers which burn wood waste for many years. Moreover, by recently, the equipment which aims at greenhouse gas discharge curtailment is also increasing by burning a waste plastic as an alternative fuel of a fossil fuel, and performing heat recovery.
In such a background, Takuma supplied the boiler plant which burns wood waste and waste plastic on the fixed fire grate, and performs heat recovery, in DENKI KAGAKU KOGYO Co., Ltd. of Nigata Prefecture.
Here, the outline and commissioning result of this plant are reported.
At the present, the ASR(Automobile Shredder Residue)and the wasted low grade electronic printed board are filled in the ground mostly due to difficulty of treatment for them. At the KOSAKA SEIREN Co., Ltd. the fluidised bed combustion boiler by which the ASR and the wasted low grade electronic printed board are burned in order to recycle of the metal and the energy of the metal and the energy of them. The outline and operation data of the plant will be introduced as follows.
We have delivered a power generation plant with a fluidized-bed boiler to Hokkaido Chiiki Danbou (District Heating) Co., Ltd. of Sapporo City that serves the regional community with heated water for heating and cooling. The plant burns RDF from wood chip and waste paper. In this article, we report on the plan outline and the test run results.
We won an order for The Refuse Derived Solid Fuel Facility from Fuchu-City in Hiroshima Prefecture in September 2000. We commenced designing work starting in September 2000, and launched a construction work on site starting in July 2001. The completion of the plant took place in October in 2002 by way of successful trial operation and functional verification tests starting in from July 2002.
The Refuse Derived Solid Fuel Facility for Funchu-City has the plant throughput of 60ton/8h, and it is constructed with 30 ton/8h×2 systems. General refuse which has been carried in will be stored once in refuse pits, crushed by crusher, dried by drier, converted into solid fuel by compression molding machine, temporarily stored in solid fuel storage facility, and then carried out of the yard.
Regarding the above-mentioned Refuse Derived Solid Fuel Conversion Facility, the outline and the test results of trial operations will be reported.
Recently, there is a serious need for a quick and inexpensive method of analyzing dioxins. In response, we have developed one using ELISA, and began marketing the analysis kit and soliciting for toll analysis orders in April of this year.
The analysis results from exhaust gases, fly ash and soil obtained by the ELISA method developed by us, and those by the HRGC/HRMS method coincide closely, with the coefficients of correlation of more than 0.97. Moreover, the cost of analysis by our method is roughly 1/4 of that by HRGC/HRMS method, and the measuring time, not including the pretreatment of the sample, is only about four hours.
In this paper, we reported on the principle and characteristics of the ELISA method we have developed.
