Surface Condensers The surface condensers are of two types : (I) Surface condensers : In this the steam flows outside the network of tubes and we flows inside the tubes. (II) Evaporative condensers : In this the condenser shell is omitted. The steam puses through condenser tubes and over these tubes the water is sprayed … Read more
Types of Condenser Condensers are mainly of two types viz, (a) Jet condensers (b) Surface condensers. In case of jet condensers the exhaust steam and the cooling water come in direct contact and as a result the steam is condensed. The temperature of condensate and the coolant is same while leaving the condenser. These are … Read more
Functions and Location of Boiler Mountings The function and location of various mountings necessary for control, safe working and maintenance of boilers along with accessories for its efficient operation are given in Table. Sr. No. Name of Boiler Mounting Function Location A. For safe working of boiler 1. Pressure gauge To indicate working pressure of … Read more
Elements of Condensing Plant Figure A Figure B The various components of a condensing plant are shown schematically in Figure A and B depending upon the availability of cooling water needed for condensing the exhaust steam. In case of large capacity power plants, the requirement of cooling water is millions of litres per hour. If … Read more
Introduction to Condensers and Advantages of Condensers In order to develop the maximum work, according to the Carnot’s principle, the heat must be supplied at the maximum possible pressures and temperatures and the heat should be rejected at minimum pressures and temperatures. However, the heat supplied depends upon the pressure of steam to be generated … Read more
Boiler Mountings and Accessories The necessary devices installed or mounted for the safety of boiler and its control are called boiler mountings, The devices which are installed in the boiler for their efficient operation and smooth working are called boiler accessories. Boiler mountings form an integral part of the boiler. They are necessarily required to … Read more
The Carnot Vapour Cycle It has been proved earlier that Carnot cycle is the most efficient cycle operating between the specified temperature limits. Therefore, first we shall consider the Carnot cycle as the prospective ideal cycle However, subsequently it will be shown that Carnot vapour cycle is not suitable for practical development of steam power … Read more
Difference Between Smoke tube boilers and Water tube boilers Sr. No. Smoke tube boilers Water tube boilers 1. In this the hot flue gases flow in the tubes surrounded outside by the water. In this the water flows in the tubes surrounded outside by the hot gases. 2. These boilers have large water to steam … Read more
Babcok Wilcox Boiler This is one of the most important type of a water tube boiler generally employed in the power houses for power generation as shown in Figure. It consists of number of inclined water tubes (WT) connected between the uptake header (UH) and the downtake heater (DH). Headers are provided with hand holes … Read more
Smoke Tube Boilers Q. Smoke Tube Boilers or cochron boiler diagram. In these boilers the flue gases pass through the tubes which are surrounded by water in boiler shell. Some of the boilers of these type are being discussed below. Cochron Boiler : It is a fire tube boiler in which the flue gases from the … Read more
