For a long time, shell-and-tube heat exchangers have been the most common choice in industry. Despite some limitations, their main advantage is that they extensively investigated and reliable design tools are readily available. In other words, any alternative should not only outperform exchangers, but also be equipped with comparably robust platform for engineers. recent years, growing market share can observed plate particularly special class known as pillow-plate exchangers. Recently,...

This paper synthesizes insights from industrial experts academic researchers on the challenges, opportunities solutions of integration thermal storage (TES) systems. These were gathered during an international expert workshop TES, organized by European Energy Research Alliance as part Joint Program Efficiency Industry (EERA-JP EEIP) November 7th, 2023, discussing a white...

Building integrated photovoltaics (BIPVs) have become increasingly popular in urban areas due to their potential provide zero-emission energy buildings. BIPVs enable the use of MO photovoltaic (PV) modules, resulting multiple generation peaks throughout day, which can closely match consumption profile a building. However, designing PV output power forecasting model for be complex, as may occur. In general, prior works focused on design and study impact tilt azimuth angle variations annual...

Biocarbon has a great potential to replace fossil reductants and help reduce greenhouse gas emissions from carbon intensive metallurgical industries. In this work, biocarbon samples were produced Norway spruce under different final temperatures (550, 650 800 °C) holding times (10 30 minutes). The CO2 gasification reactivity of the biocarbon, or biomass char, was investigated in thermogravimetric analyser at (850, 900 950 °C). results show that wood char higher carbonization temperature is...

Modern wood stoves can achieve high efficiency and relatively low levels of harmful emissions. However, controlling logs' combustion remains challenging, the emission unburnt compounds are generally higher than for e.g. pellet stoves. One solution is to upgrade fuel quality, enabling a more stable process. Thermal upgrading through carbonization yields highest achievable quality solid from wood. In this work, two types charcoal were tested in commercially available stove at various loads,...

Two commercial, one light- and heavy oil burner for a CEN 250 kW boiler was modified by simple means to allow operation at controlled dry oxy-fuel conditions. The variables measured both air- oxy-firing were the flue gas components; CO2, CO, O2 NOx, exit temperature water temperatures (in/out). Both burners run on air based base cases comparison. fired 90 130 kW, respectively. For light an experimental matrix consisting of five runs with varying excess air, λ = 1.1-1.25, ratio performed....

Wood heating is an important worldwide source of emissions particulate matter, comprising black and organic carbon. In Norway, woody biomass combustion a significant particle emissions. 2013 about 1.2 billion tons wood logs were burned, according to the response from annual questionnaires made by statistics Norway. About 1.0 million burned for household heating. 54% was in stoves with new technology (in 550 000 stoves) while remaining burnt old 420 stoves). The motivation this investigation...

Abstract The ZEB Lab project, coordinated by SINTEF and NTNU, aims at building a (Zero Emission Building) in Trondheim (Norway) 2019, to be used both as office living laboratory. An innovative latent heat storage (LHS) unit using phase change material (PCM) will integrated the centralized heating system. LHS able store excess from various sources connected system, when they are not required for space heating. One challenge is make use of full potential PCM have compact effective unit, while...

Industrial low-temperature freezing applications are often batch processes, requiring a lot of energy, exerting stress on the electrical grid. To relieve this stress, thermal energy storage can be used. However, there is lack suitable material for low temperature (around −50 °C). Under high pressures, carbon dioxide used as phase change temperatures around −55 °C. In study, parametric study was conducted design and operational parameters an industrial-scale pillow plate heat exchanger with...

A latent heat storage was in 2021 installed an office building Trondheim, Norway. The unit contains 3 tons of CrodaTherm 37, which is a bio-based wax phase-change material with melting temperature 37 degrees Celsius. thermal energy can be charged from pumps or district heating and discharged to domestic hot water, radiators, ventilation, pumps.
