Life cycle assessment of heat production from …

In Poland, coal is the main fuel used for heat production. Innovative clean coal technologies, which include underground coal gasification (UCG), are widely developed. This paper presents the analysis results of life cycle assessment (LCA) and material flow analysis (MFA) of using synthesis gas from UCG for heat production. The paper presents the results of a comparative analysis of MFA and

Characteristics of boiler feedwater - Lenntech

The composition of boiler feed water must be such that the impurities in it can be concentrated a reasonable number of times inside the boiler, without exceeding the tolerance limits of the particular boiler design. If the feed water does not meet these requirements it must be pretreated to remove impurities.

Combining solar power with coal-fired power plants, …

The need for good solar radiation means that the uptake of coal-solar hybrids will be limited. Cofiring natural gas has wider potential: currently, the largest near-term market appears to be for application to existing coal-fired plants in the USA. However, where gas is available and affordable, potential markets also exist in some other countries.
