Inert Gas on board Tankers - All you need to know!

Apr 04, 2018 · When using flue gas from a main or auxiliary boiler, an oxygen level of less than 5% can generally be obtained, depending on the quality of combustion control and the load on the boiler. When an independent IG generator or a gas turbine plant with afterburner is fitted, the oxygen content can be automatically controlled within finer limits

Wood-burning stove - Wikipedia

A wood-burning stove (or wood burner or log burner in the UK) is a heating appliance capable of burning wood fuel and wood-derived biomass fuel, such as sawdust bricks. Generally the appliance consists of a solid metal (usually cast iron or steel) closed firebox, often lined by fire brick, and one or more air controls (which can be manually or automatically operated depending upon the stove).

What is an Inert Gas or IG System on Ships?

Jan 08, 2021 · The basis of inert gas production in the IG plant is the flue gas generated from the ship's boiler. The high temperature gas mixture from the boiler uptake is treated in an inert gas plant which cleans, cools and supplies the inert gas to the individual tanks via PV valves and breakers to ensure safety of tank structure and atmosphere.

Coal Combustion Theory | Electrical4U

Feb 24, 2012 · Remember the unburnt gas loss is mainly the result of burning carbon to carbon monoxide instead of carbon dioxide. It is seen that heat release in CO reaction is one third of that in CO 2 reaction. So adequate supply of oxygen or excess air will quickly reduce this loss to zero. Dry Flue Gas Loss. A further loss of heat is that due to dry flue gas.

Coal - Wikipedia

Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

The fixed glass panels covering direct-vent fireboxes ensure that the furnace- or boiler-heated air in the rest of the house doesn't escape up the flue, as it does with a wood fire. You can get as much as 75 to 99 percent of a fuel's energy back as heat, instead of the 10 to 30 percent for wood fires.
