✦ Synopsis

However. the development of a commercial market with fewer regulations tends to level out prices. Consumers on the household market purchase small quantities and do not have the same possibility as district heating companies to take advantage of the oversupply opportunity and thus face a faster price development. In addition, the weaker market position of the consumers also tends to give homogeneous prices between regions for the residential sccror.

Research on the process of biomass formed coke Zhou, S. et ul. ,%'cirun Zhuanhna. 1999, 22, (2). 62-65. (In Chinese) Biomass is used as a caking additive in the hriquetting of coal. After they are dried and mixed. hiomass. anthracite and bituminous coal are hriquetted at the normal temperature. Research was conducted into the effects of the biomass and bituminous coal content, hriquetting force and coal class on the compressive strength of briquette and formed coke. The experimental results demonstrate that all of the four factors have significant effects on the compressive strength of briquette. However, only the bituminous coal content and hriquetting force have a marked effect on the strength of formed coke. The preferred process conditions include, 18% biomass. a I :2 ratio of anthracite to fat and a hriquetting force of 460 kN.
