Influence of heat pumps inclusion in deaeration scheme of heating network make-up water on the operating modes of the TPP

Abstract

The idea of using a heat pump in the heating cycle seems quite attractive at first glance, but requires careful analysis of the effect of the heat pump on the operation mode of the thermal power plant. In this work we analyze the influence of the heat pumps inclusion in deaeration schemes of heating network make-up water on the operating modes of the CHP. All calculations were made for the real scheme of the de-aeration plant DSV-800 of the power unit with a T-100 turbine. The calculations were carried out for three schemes of heat pumps of different capacities. The calculations took into the account various uses of the heat received from the heat pumps.

Efficiency of using heat pumps with various refrigerants in real steam turbine power units with PT-80 and T-250 turbines

“…The working fluid -the refrigerant -is an extremely important element of the operation of HP [18][19][20][21][22][23][24]. The choice of refrigerant is often made for various reasons:…”

Features of Russian regulatory framework governing cathodic protection of heating networks against external corrosion in the ground

“…Thus, both GOST 51164-98 and GOST 9.602-2005 (these normative documents are still in effect), demonstrate a unified approach to the issue of implementing anticorrosive measures. They (anticorrosive measures) are determined by regulatory documents, and the choice of the most effective option is not required [5][6][7][8][9]. Moreover, the current instructions, particularly "Standard Instruction for the Protection of Pipelines of Heating networks from External Corrosion" and the "Instruction for the Protection of Urban Underground Pipelines from Corrosion", created on the basis of the Soviet normative act "Instruction for the Protection of Urban Underground Pipelines from Corrosion ", reproduce the same outdated ideology of anticorrosion protection.…”
