Waste heat recovery from high temperature slags represents the latest potential way to remarkably reduce the energy consumption and CO₂ emissions of the steel industry. The molten slags, in the temperature range of 1723–1923 K, carry large amounts of high quality energy. However, the heat...

This paper presents a significant method and a basic idea of waste heat recovery from high temperature slags based on Time Temperature Transformation (TTT) curves. Three samples with a fixed CaO/SiO₂ ratio of 1.05 and different levels of Al₂O₃ were designed and isothermal experiments were...

This paper investigated the cooling processes of high temperature slags using SHTT (single hot thermocouple technique) and CFD (computational fluid dynamics) method for the purpose of recovering the waste heat. A series of slags with the CaO/SiO2 ratio of 1.1 and different Al2O3 contents were...

State and local debt and the debt of quasi-public agencies have grown in importance as a result of fiscal decentralization, rapid urbanization, and the increasing role played by private capital. However, with debt comes the risk of insolvency. This note outlines a set of aligned fiscal...

This paper explores the building blocks of an institutional framework to govern borrowing by subnational entities to finance infrastructure investment. The framework should help in achieving sustainable financing of development needs and sound management of fiscal risks. Based on international...

In the present paper, a five-column heat integrated methanol distillation scheme is proposed with the aid of process simulation and pinch analysis. Unlike the popular four-column (or 3 + 1 column) scheme, a medium-pressure column is added after the light ends column in this novel scheme. The...

Does decentralization enhance service delivery and poverty reduction? Drawing on cutting edge research, expert contributors address this fundamental question facing policy-makers in developing as well as advanced countries. This timely book builds upon insights on the recent developments in the...
