Process chamber Sample Clauses
Process chamber. Process chamber including its accessories shall operate as follows:
1. The unit shall be able to handle a mixture of solid, sludge and liquid inorganic and organic feedstock.
2. In the presence of heat and steam the organic material in the chamber shall be converted into syngas. The temperatures in the process chamber shall be high enough to allow destruction of organic material.
3. A steam generator shall feed controlled amounts of steam to the process chamber as demanded by the steam reformation process.
4. After gasification, the remaining inert material including metals and minerals, referred to as residues, shall be heated to a molten state in the process chamber.
5. The gas discharge line shall be equipped with a pressure relief device based on a water seal tank concept.
6. The molten material shall retain radioactive and non-radioactive metals (except those having low vapor pressure at the operating temperature).
7. Fluxes and other additives shall be introduced in the process chamber to improve the handling and quality of the residues. The residues shall meet the EPA leachability tests as defined by TCLP test protocols. The residues shall also meet the performance requirements of the Hanford site Solid Waste Acceptance Criteria.
8. A pre-heater device is provided to control process chamber temperature during the initial start-up as well as shut-down and idle periods.
9. The process chamber refractory lining shall be of modular design to allow ease of refractory replacement or other wise have provisions for change out. -------------------------------------------------------------------------------- 12/8/97 GASIFICATION/VITRITICATION SYSTEM PURCHASE AGREEMENT ATG/IET Proprietary and Confidential --------------------------------------------------------------------------------
Process chamber. The process chamber is a rectangular furnace body with a movable lid on top. The chamber lid is fixed to the furnace body The process chamber is double-walled for water cooling The process chamber is designed to operate the furnace with a pressure of approx. 1 - 900 mbar. The inside walls are made out of stainless steel, the outside walls are made of mild steel. Process Chamber, mainly consisting of:
(1) Double walled chamber body, water-cooled inner chamber parts made of stainless steel, with mating flanges for the lid. Outer furnace will be made out of mild steel.
(1) Port for the pumping unit
(2) Ports for the high-current feed-through for the heaters
(1) Set of stainless steel protection plates. These protection steel plates are to be placed temporarily between hot zone and chamber wall during the bake-out procedures in order to collect condensable organic compounds and, by this, reduce contamination of the chamber.
(1) Port with feed through for TC measurement
