The article discusses the evaluation of potential heat production options for a large-scale district heating system in Narva (Estonia). Heat is currently generated at Balti Power Plant’s CHP unit using local oil shale mixed with biomass. consists two circulating fluidised bed boilers and reheat steam turbine. According to development strategy, expected achieve carbon neutrality future. Various ...

Gasification experiments were carried out in a pilot scale fluid bed reactor operated under allothermal mode and low fluidisation regime with iron-doped olivine char as catalyst for in-situ tar abatement. The combination resulted reduction of 50% the overall yield respect to reference values. Furthermore, integration an oxidative Hot Gas Filtration unit downstream gasification led further relat...

In this work, a three-dimensional CFD model for the gas–solid flow of two different particle sizes in CFB riser coupled with kinetic theory (KT) has been developed. The properties solid phases are calculated using proposed multi-particle theory. is implemented commercial software CFX4.4. current model, one gas phase and used. However, generalised carrier N number to enable realistic size distri...

Thermochemical energy storage (TCES) has a vital role to play in future where 100 % of our domestic needs are generated by renewables. Heating and cooling represent 51 total consumption, as such contribute highly greenhouse gas emissions. As society, we have effective solutions for this the form renewable sources, primary two being: solar thermal heat wind power. However, one issue plagues thes...

Lignocellulosic biomass and waste, such as plastics, represent an abundant resource today, they can be converted thermo-chemically into energy in a refinery. Existing research works on catalytic non-catalytic pyrolysis performed thermally-heated reactors have been reviewed this text, along with those microwave-heated ones. Thermally-heated reactors, albeit being the most commonly used, present ...

Mud volcanoes, ranging in size between 50cm and 800m high, are found both on land and in submarine environments. Their variation in height and shape reflects the driving forces building them and the physical properties of their materials. The driving force behind the construction of mud volcanoes is overpressure of fluidised mud at depth within the sediment column. Although some component of ov...
