This document discusses investigating improvements to boiler efficiency through adding an additional bank of tubes to the economizer for supercritical steam power cycles. It begins by introducing economizers and how they recover heat from flue gases to preheat feedwater, improving boiler efficiency by 2-4% typically. The study aims to add another bank of tubes to existing economizers in NTPC units to further control pollutants and increase feedwater temperature for both subcritical and supercritical conditions. Heat transfer calculations are performed assuming the additional bank and comparisons are made between existing and modified unit efficiencies. Overall pros and cons of adding the extra bank of tubes in the economizer are examined.

Heat pumps are devices that move thermal energy in the opposite direction of spontaneous heat flow by absorbing heat from a cold space and releasing it to a warmer one. There are two main types of heat pumps - vapor compression cycles which use a compressor to move heat and vapor absorption cycles which use a heat source like gas or steam instead of electricity to run the pump. Heat pumps have various applications like space heating and cooling, domestic hot water, industrial processes, and more. They are evaluated based on their coefficient of performance and energy efficiency. While efficient when temperatures are similar, noise from mechanical components and efficiency limits due to thermodynamics present issues.

OBJECTIVES:
To fully exploit the self-replenishing ‘renewable-energy’ from the air and provide a low-carbon
emission means of energy efficiency.
To maintain the buildings internal temperature requirements and, where applicable, provide
‘domestic’ hot water.
To understand the technology: air-source heat pump systems consist of just two parts: the heat pump
assembly, and the heating-delivery system. The heat pump is basically a system of heat exchangers
near the building lifting low-temperature heat from the ambient air and uplifting it to high, useful
temperatures. A brine-mix (usually a mixture of water and antifreeze) circulates through the plate
exchangers to absorb low-temperature heat from the air when heating a building or the rejection of
heat harmlessly back to the air when cooling a building.
To engage a specialist heat pump contractor to ensure the supply of major components, the
installation, testing, commissioning, and balancing of an air-source heat pump system.
