where bulky items are shredded, and ferrous, glass, and other recyclable materials are recovered from
the entire stream, using manual sorting. Thus, the as-received waste going to the incineration facilities
(both FBC and non-FBC) is really a prepared fuel, having a non-combustibles content of only 4 percent,
minimizing residue disposal requirements, and reducing fuel preparation requirements at the FBC facility
(012).
C.2.3.5.1 Machida Refuse Resources Recycling Center. The Machida Refuse Resources
Recycling Center is a municipal facility constructed by the Machida Municipal Government in Tokyo,
Japan In 1982. The facility was designed to handle the waste from a population base of 370,000. It
incorporates a "Recycle Plaza" where recyclable material is recovered from the incoming waste. The
remaining material is sent to a receiving pit, from which it is fed to a refuse crusher for size reduction to
approximately a 4-inch particle size. No further processing of the incoming refuse is employed. The
material is then burned in a fluidized-bed combustion system. Energy recovery is employed to generate
steam for heating and air conditioning of the Recycling Center. Electricity is generated for internal plant
use only.
The MSW combustion system consists of three IHI fluidized-bed combustors, each capable of burning
150 tons per day of incoming refuse. These units are the largest FBCs installed in Japan for the
combustion of MSW. Normally, two units are active and one is kept available as a backup. The units
are bubbling-bed combustors with a gravity overbed feed system. A bed management system is
employed which allows the bed material to be continuously removed, screened, and re-fed to the
combustor during operation. This allows the buildup of oversized non-combustibles in the bed to be
controlled, an important feature in MSW-fired FBCs.
Each FBC boiler has a steam generating capacity of 36,000 lb/hr at 360 psig. Two 2,000 kW condensing
turbines are used to produce power for in-house consumption. Power generation is controlled to
maximize electricity production without exceeding the in-house demand because the plant is not
permitted to sell power back to the utility (672).
A limestone feed system is employed for in-situ acid gas control, and may provide some level of bed
fusion control as well. An electrostatic precipitator is used for particulate emission control. No other
pollution control systems are employed by the plant.
At the time the plant was commissioned, performance tests were conducted which indicated that the
facility was operating in compliance with its emissions limits at predicted processing rates.wTe CORPORATION
