The coal will pass by the coal gate to burn in the furnace from coal feeder. And the coal slag will be exhausted by the slag remover. 4. There is an electric control cabinet equipped with the boiler. The cabinet includes indicator of the Thermal Parameter‚ induced and forced draft fan‚ control buttons of the electric actuators‚ and over- temperature alarm

countries began to formulate extensive research and development programmes to exploit solar energy . One way to tap solar energy is through the use of solar ponds. Solar ponds are large-scale energy collectors with integral heat storage for supplying thermal energy. It can be use for various applications‚ such as process heating‚ water desalination‚ refrigeration‚ drying and power generation. Solar energy is an abundent and renewble energy source.the annual solar energy incident at the ground in india

plastic-def. A plastic material is any of a wide range of synthetic or semi-synthetic organic solids that are moldable. Plastics are typically organic polymers of high molecular mass‚ but they often contain other substances. They are usually synthetic‚ most commonly derived from petrochemicals‚ but many are partially natural. Plastics Characteristics Plastics are made from fossil fuels--petroleum‚ natural gas‚ coal--‚ wood and some plant materials‚ air‚ water and sometimes other common materials

CHAPTER I INTRODUCTION Pollution is one of the main problems the world faces today. One of the reasons is the overload of non-biodegradable objects like plastics‚ cans and Styrofoam. The invention of plastics and Styrofoam made a huge change in our society and it helped us in many ways. But it is also one of the main pollutants that destroy our planet. Because of these we devised a way to recycle used Styrofoam‚ and this is to make glue out of it. This glue can help reduce the number of Styrofoam

Flat-Plate Solar Collectors The Absorption of Solar Radiation A flat-plate solar collector usually has a non-selective or a selective black plate with one or two glass covers a few centimeters above the black plate‚ and a well insulated back. The length of the plate is typically about 2m. Edge effects are usually small. The transmittance () of a glass cover for solar radiation depends on the angle of incidence . Typical values for clear glass are given in Table 1. Table 1. Transmittance of a Glass

If it uses more than other models of water heaters‚ replace it with a more efficient one. * Put insulation around the pipes going in and out of your water heater. If you have an older water heater‚ put an insulated blanket around it. * If you will be out of town for more than a couple days‚ turn off your water heater. * About once a year‚ drain
