A rocket is an aircraft propelled by expanding gases generated by an engine using self-contained propellants (i.e., rocket fuel) and not dependent on the intake of outside substances (such as air). You probably won’t need to list a rocket on your private certificate anytime soon, but a...
Air pollution consists of various types of chemicals and gases being passed into our atmosphere. __{1}__ Second to that is industrial factories that release dirty and dangerous smoke into the atmosphere. Pollution has been linked to numerous types of illnesses such as strokes, heart issues and...
There are three types of volcanoes(火山):dormant and active. An active volcano is one that has erupted(爆发) in the past thousand years or so. Volcanoes are active if they are causing earthquakes or out gases. A volcano is dormant if it is erupted for long, but it is expected to in ...
These products are tradable commodities on carbon markets and represent the right to emit one metric ton of CO2 or an equivalent amount of other greenhouse gases (IPCC 2023). Understanding the value of carbon credits is essential, especially in the context of global agreements such as the Kyoto...
With nearly a quarter of global greenhouse gases coming from all types of transportation, can we keep ourselves off gas-powered vehicles to avoid the worst effects? As more governments take urgent action on climate change, quite a few companies are betting their future-that millions of consumers...
Air Preheaters (APH) are the Shell and tube type Heat Exchangers used for preheating the air which is fed to the boiler or furnaces/kilns for combustion of fuels. The Air Pre heater’s primary objective is to extract the waste heat from the flue gases leaving the boiler. Thermodyne Engine...
