1 MWe ORCHID©, FMGC, France / 1 兆瓦 ORCHID©机组,FMGC铸造厂,法国

Enertime’s first ORC ORCHID module will be installed in the FMGC foundry in Chateaubriand/Soudan in Western France. The unit will be placed at the outflow of the combustion chamber of a cupola furnace to recover waste heat from the process and transform it into electricity. The cupola is a foundry equipment producing cast iron from scrap iron and coke. The process emits large amounts of CO that is burnt in a combustion chamber and then cooled down for flue gas treatment. The 1 MW ORC unit is connected to the flue gas cooling system to recover the heat via thermal oil at 200°C. The cupola furnace has a production capacity of 20 tons per hour with a maximum capacity of 30 tons per hour and runs 24 hours a day, 5 days a week. The amount of heat that will be recovered is 5 to 6 MWth. The power generated by the ORC unit will be injected into the foundry grid for 5,000 MWh per year. The ORC unit will make the existing cooling system redundant, saving another 100 MWh a year. Enertime ORC unit was designed to make its installation in an industrial environment easier. The design of the module focuses on energetic performance combined with reliability and ease of operation. The French Technical Center of the Foundry industry (CTIF) and the engineering department of the foundry took part in the project together with the cupola furnace and the cooling system manufacturers. The Company TOTAL and the National Agency for Environment and Energy Management (ADEME) will provide financial support to the project. The goals of the project are to:

Enertime 第一个ORC ORCHID 机组将被安装在位于法国西部夏多布里昂/苏当地区的FMGC铸造厂。这个机组安装在化铁炉燃烧室的出口来回收铸造过程中的废热,用来发电。化铁炉是一个将废铁和焦炭转化成铸铁的铸造设备。这个过程会产生很多的CO,之后会在一个燃烧室中燃烧并被冷却后作为炉气处理。此1Mw的ORC机组连接到炉气冷却系统,在200°C通过热油回收热量。化铁炉的生产能力为20吨每小时,最大为30吨每小时,每天24小时,一周5天。可回收的热量大约在5到6MWth。ORC机组将会并入铸造厂电网,每年提供5000兆瓦的电量。ORC机组将会使现有冷却系统冗余,每年多节省100兆瓦。Enertime ORC 机组的设计使其会被轻易地安装在工业环境中。机组的设计致力于更强劲的性能,并具有高可靠性和易于操作。法国铸造业技术中心(CTIF)和铸造厂的工程部参与了化铁炉和冷却系统的制造。道达尔公司和法国国家环境与能源管理局(ADEME)为项目提供了资金支持。此项目的目的如下:

  • Validate the conception, building and on-site operation of the ORCHID unit for a significant operation period.
  • 在正式运营条件下,验证ORCHID机组的设计,制造和运行状况
  • Study the impact of the unit on the industrial process and implement appropriate corrective measures.
  • 研究机组对工业流程的影响并提供修改性的措施
  • Confirm the economic relevance of such a waste heat recovery system on the short and middle terms.
  • 在短中期确认废热回收的经济效益
Cast iron tends to be brittle, except for malleable cast irons. With its relatively low melting point, good fluidity, castability, excellent machinability, resistance to deformation and wear resistance, cast irons have become an engineering material with a wide range of applications and are used in pipes, machines and automotive industry parts, such as cylinder heads (declining usage), cylinder blocksand gearbox cases (declining usage). It is resistant to destruction and weakening by oxidation (rust).
A cast iron foundry is an industrial installation that produces iron castings or molded items. 
These installations or cast iron foundry feature a multi-step process that involves the melting of iron stock in furnaces, then pouring the molten metal into molds. 
Cast Iron foundry is one of the oldest types of metal smelting operations and produce millions of tonnes of product each year.
