Sensotronic Brake System Energy conversion and equipment are closely related due to industrialisation and increase in population our environment is polluted vigorously. Many of the industries and fossil fuel power plant emit CO2, CO, particulate matter, heat and other poisonous gases to the atmosphere. Resulting many problems like global warming, health hazards, environmental degrading etc. We need clean air, atmosphere and surrounding for good health and better quality of living. The energy needs are increasing due to industrial advancement higher standard of timing, increasing population etc. There is no way other than increasing the production of usable energy. But we know that every man made energy conversion has contain degrading effect on the environment. The task is to convert energy with out exceeding the limits of pollution. So every one of as has a question how to control the pollution. Various alternatives are being examined and studied about the employment of different pollution control equipment by National Environmental protection agency and environmentalist. One of the instrument which control the quantity of particulate matter is Electro-static precipitator.
