Meisenzahl, Joel Mokyr Chapter URL: http://www.nber.org/chapters/c12364 Chapter pages in book: (p. 443 - 479) 9 The Rate and Direction of Invention in the British Industrial Revolution Incentives and Institutions Ralf R. Meisenzahl and Joel Mokyr 9.1 Introduction The Industrial Revolution was the fi rst period in which technological progress and innovation became major factors in economic growth. There is by now general agreement that during the seventy years or so traditionally associated with the Industrial Revolution, there was little economic growth as traditionally measured in Britain, but that in large part this was to be expected.1 The sectors in which technological progress occurred grew at a rapid rate, but they were small in 1760, and thus their effect on growth was limited at fi rst (Mokyr 1998, 12– 14). Yet progress took place in a wide range of industries and activities, not just in cotton and steam. A full description of the range of activities in which innovation took place or was at least attempted cannot be provided here, but inventions in some pivotal industries such as iron and mechanical engineering had backward linkages in many more traditional industries. -
Design and Implementation of Energy Saving Control and Regulation System for Metallurgical Furnace
Design and Implementation of Energy Saving Control and Regulation System for Metallurgical Furnace ShuWen Chen, YongShen Chen, and WeiWei Guo { [email protected]} School of materials and metallurgy University of Science and Technology Liaoning Anshan 114051, China Abstract. This paper from the perspective of saving fuel gas, reasonable design of temperature control system. The thermostat is designed S7-200 series PLC adoption. The communication method of the computer and programmable controller (PLC) temperature control system is described. Software part of the application of the PLC principle to achieve system control. Hardware part of the temperature sensing element thermocouple temperature field, flow meter, fuel flow regulation, adjusting the thermocouple output electrical signal supply line for comparison with the given values, if there is a difference, the difference through the operational amplifier and issued a directive to the actuator, the actuator to perform the task. The simulation interface of the application configuration, virtual reality condition, the master-slave real-time monitoring system composed of computer and PLC to give full play to the their respective advantages in the industrial control, realize the decentralized control and centralized monitoring and other new features. Write part of the program, to research on energy efficient and reasonable utilization as the theme, combined with typical furnace, energy for metallurgical furnace the huge energy consumption equipment rational utilization and effective control method is put forward to improve the reasonable design of the program, resulting in applications get effective implementation, for enterprises to save energy, create economic benefits to contribute. Keywords: PLC; control; computer; configuration technology. 1 Introduction So far the majority of domestic metallurgical furnace is built in the last century, the control system configuration has been outdated. -
