Waste land Reclamation

Waste land :

The land which is not in use is called waste land. The waste land is unproductive, unfit for cultivation, grazing and other economic uses. About 20% of the geographical area of India is waste land.

Type Of Waste land :

Waste lands can be divided into two types

1.Uncultivable waste lands

2.Cultivable waste lands

1. Uncultivable waste lands : These lands cannot be brought under cultivation.

Examples - Barren rocky areas, hilly slopes, stony or leached or gully land (or) sandy deserts, etc.,

2. Cultivable Lands : These are cultivable but not cultivated for more than five years. Cultivable waste lands are important for agricultural purposes.

Examples - Degraded forest lands, gullied lands, water logged and marsh lands, saline lands, etc.,

Causes of Waste land formation :

1. Due to soil erosion, deforestation, overgrazing, water logging, salinity.

2. The increasing demand for fire-wood and excessive use of pesticides.

3. Developmental activities like construction of dams and power projects have caused considerable damage to land due to water logging.

4. Over-exploitation of natural resources.

5. By the Sewage and Industrial wastes.

6. Mining Activities destroy the forest and cultivable land.

MELTING FURNACES FOR FERROUS METALS : CUPOLA AND ITS WORKING

Various types of melting furnaces are used in different foundry shops, depending upon the quantity of metal to be melted at a time, and the nature of work that is carried out in the shop. The primary objective in cupola is to produce iron of desired composition, temperature and properties at the required rate in the most economical manner. Besides, this furnace has many distinct advantages over the other types, e.g., simplicity of operation, continuity of production, and increased output coupled with a high degree of efficiency. Description Of a Cupola : The Cupola Furnace consists of a vertical, cylindrical steel sheet, 6 to 12 mm thick, and lined inside with acid refractory bricks or acid tamping clay. The refractory bricks or the tamping clay used consist of silicon oxide acid (SiO2) and alumina (Al2O3). The lining is generally thicker in the lower where the temperatures encountered are higher than in the upper region. The shell is mounted either on a brick work fo...

SIMPLE CARBURETOR - CONSTRUCTION AND WORKING

CONSTRUCTION OF SIMPLE CARBURETOR : The main Components of Simple Carburetor are : Float Chamber, float, nozzle, venturi, throttle valve, inlet valve, and metering jet . In the float chamber, a constant level of petrol is maintained by the float and a needle valve. The float chamber is ventilated to atmosphere. This is used to maintain atmospheric pressure inside the chamber. The float which is normally a metallic hollow cylinder rises and closes the inlet valve as the fuel level in the float chamber increases to certain level. The mixing chamber contains venturi, nozzle and throttle valve. The venturi tube is fitted with the inlet manifold. This tube has a narrow opening called venturi. A nozzle is provided just below the centre of this venturi. The nozzle keeps the same level of petrol as that of the level in the float chamber. The mixing chamber has two butterfly valves. One is to allow air into the mixing chamber known as choke valve. The other is to al...

Advantages And Disadvantages Of Air Refrigeration System :

Advantages Of Air Refrigeration : 1. The refrigerant used namely air is cheap and easily available. 2. There is no danger of fire or toxic effects due to leakages. 3. The weight to ton of refrigeration ratio is less as compared to other systems. Disadvantages Of Air Refrigeration : 1. The quantity of Refrigerant used per ton of refrigeration is high as compared to other systems. 2. The COP of the system is very low. Therefore running cost is high. 3. The danger of frosting at the expander valves is more as the air contains moisture content.
