Working Of Lithium - Bromide System

 * Lithium Bromide System is another type of  absorption refrigeration uses water as refrigerant and lithium bromide as absorbent. 




 * This System is mainly used for water - chilling purposes.

 * Water to be chilled is passed through tubes. Refrigerant water, after expanding in the expansion  valve  is  sprayed over these tubes.

 * Because of this, the tube water gets chilled and the refrigerant water becomes water vapor.

 * Lithium Bromide solution , which is sprayed in the absorber, absorbs the water vapor. Thus, the  solution becomes weak.  

 * The Weak Solution is pumped to the generator. Here, heating of the solution is done. Because of this, some water evaporates. So, the solution becomes strong. 

 * This Strong Solution is passed through the heat exchanger and sprayed in the absorber. Thus the cycle  repeats.

 * Water vapour formed in the generator is passed through a condenser. Water vapor, thus gets  condensed  and becomes liquid water.

 * External supply of cooling water will affect the condenser. 

 * This cooling water is supplied through the absorber, to carry some heat from there.

 * Condensed water (from the condenser) is supplied to the evaporator to make up for the water vapor formed there.

THROTTLE GOVERNING OF STEAM TURBINES

Steam Pressure at inlet to a steam turbine is reduced by throttling process to maintain the speed of the  turbine constant at part load and hence this method of governing is called "Throttle Governing".  Construction : Throttle governing system consists of  a centrifugal governor, a lever , an oil pump , a pilot piston , control valve , a relay piston and a throttle valve. The throttle valve is moved by a relay piston. The relay piston is actuated by pilot piston control valve. There are two piston valves covering ports in the pilot piston control valve without any overlap. These piston valves are operated by lubricating oil supplied by a gear pump at 2 to 4 bar. The oil returns to the drain from this chamber.  Working : When the turbine works on full rated load, the throttle valve will remain open. When the load is decreased, the energy output of the turbine becomes in excess and the turbine shaft speed increases. Hence, governor sleeve will lift. The upward movement of the

ELECTRICAL COMPARATORS AND ITS WORKING

Electrical Comparators are used as a means of  detecting and amplifying small movements of a work contacting elements. An electrical comparator consists essentially of  a pick-up head or transducer for converting a displacement into a corresponding change in current and a meter or recorder connected in the circuit to indicate the electrical change, calibrated to show in terms of displacement. Generally, an amplifier is needed to provide the requisite sensitivity and to match the characteristics of different parts of  the circuit. Electrical comparators can be classified according to the electrical principle used in the pick-up head. Most of the comparators use either a differential transformer, an inductance bridge, a strain gauge or a capacitor as a means of detecting movement of the gauging element. There are different types of  electrical comparators. One kind called an electrolimit gauge is used to check or measure the outside diameter of a  roll. The object to be checked is place

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.
