Micro-cogeneration (micro-combined heat and power) is a technology that simultaneously produces decentralized thermal electrical energy with power of less than 50 kWel. This consists using the waste generated by thermodynamic process to meet heating hot water demands buildings. The use biomass as fuel offers important advantages: renewable energy, carbon neutrality, availability, low cost. Furt...

This document sets forth procedures for establishing maximum emissions levels for all fossil-fuelbased thermal power plants with a capacity of 50 or more megawatts of electricity (MWe) that use coal, fuel oil, or natural gas.1 Conventional steam-producing thermal power plants generate electricity through a series of energy conversion stages: fuel is burned in boilers to convert water to high-pr...

Abstract The presented article deals with the possibility of using synthesis gas produced from municipal waste in a spark-ignition combustion engine intended for micro-cogeneration unit. subject investigation is effect fuel composition on internal parameters analysed course pressure cylinder. analysis shows that, general, increasing proportion hydrogen increases rise rate as well heat release r...

Biomass fuel energy can be utilized in cogeneration cycles through the gasification process. This reduces pollution and increases efficiency of conventional cycles, makes use renewable instead fossil fuels. In this paper, order to generate both electricity cooling, a system has been proposed using biomass Then, various ways injecting steam into each cycle are improve its performance. The follow...

The technical and economic sustainability of photovoltaic (PV) systems is heavily affected by the cost and performances of the adopted PV cells. Solar concentrators represent an effective alternative to reduce the solar cell surface and, at the same time, to increase the global conversion efficiency. Such systems include optic elements to concentrate the solar radiation to a small area where hi...

Let R be a Dedekind domain. In [6], Enochs’ solution of the Flat Cover Conjecture was extended as follows: (∗) If C is a cotorsion pair generated by a class of cotorsion modules, then C is cogenerated by a set. We show that (∗) is the best result provable in ZFC in case R has a countable spectrum: the Uniformization Principle UP implies that C is not cogenerated by a set whenever C is a cotorsi...
