Boiler and Auxiliaries Identification

kettledrum and Auxiliaries IdentificationOBJECTIVES To identify each(prenominal) major external components associated with gas fired locomote kettlefuls.To describe the function of all major components.THE FIVE MAJOR EXTERNAL COMPONENTS OF A GAS FIRED BOILERFEED-WATER SYSTEM urine bring out supply and backflow preventer The water supply comes direct from the city, and then finally into the boiler. A backflow preventer is a device used to prevent backflow. It does this finished an air gap used to provide a parapet to the backflow.Water softener system Water softeners are for pre-treatment equipment for boiler feed water, cooling towers, entire water supply and various types of process water.Feed-water armored combat vehicle The feed water is put in to the locomoteer cleanerer drum from a feed pump. In the travel drum the feed water is then turned into steam from the heating system. later the steam is used it is then dumped to the main condenser. From the condenser it is then pumped to the feed tank.Feed-water tank waste pipe valves It provides a nexus for water to enter the water tank, a connection for the tank drain, a connection for a tank hale relief valve, a connection for an air inlet valve or a water press gauge, and a connection for water to leave the tank to enter the buildings water pipe up system.Feed-water tank sight glass A sight glass is a transparent tube through which the operator of a tank or boiler can observe the level of liquid contained within.Feed-water tank temperature indication The feed-water tank temperature indication enables the plant operator to monitor/control feed-water heater levels and decrease their plants heat rate.Feed-water tank temperature control valve and sensor This helps to control scaling, corrosion, and eventually hot spots and tube failures.Chemical pumps and consume system The chemical substance pumps feed systems treat feed-water and condition blowdown sludge against corrosion and scalingBoiler 1 2 feed-water pump The pump 1 2 are used to pump feed-water into a steam boiler. The water that is supplied or returning condensate produced as a result of the condensation of the steam produced by the boilers.BOILER SYSTEMSA boiler system is simply a process used to heat up water by the means of a gas or oil-fired burner which then converts the water into steam. The steam travels through various pipes to the convectors and then generates heat used to warm the room. After a while the steam cools by condensing into water, and returns to the boiler to be heated again.BOILER AIR / FUEL SYSTEMSThe boiler dismiss system comprise of various units that is used create steam by applying heat button to water. The discharge source releases its energy in the form of combustion taking place inside the boiler furnace for the boiler to convert water to steam.Main raise line Supplies the open fire gas from outside the plant to the boilerFuel metering and regulation system Regulates the quant ity of fuel gas that is been supplied into the boiler.Main fuel shutoff valves As fuel enters through the main fuel line, the valves allow for easy shut-off of fuel flow to the boiler.Main burner pressure regulators If indispensable gas and air are inside the boiler when the burner is lit, the boiler can explode. Therefore, boiler steam pressure and water level are monitored and controlled by means of burner pressure regulator.Low and high pressure switches For spying fluid pressure. The pressure-sensing element are arranged to respond to the difference of two pressures.Blower motors Power the fans that dispense heat throughout the boiler.Air Dampers Controls the flow of air through the boiler.Igniters Converts the fuel that is being fed into the boiler through the main fuel line into heat by lighting a connected burner. cauterize scanners Monitor the boiler fires and detect the presence or absence of flame in a boiler.steamer SYSTEM, EXHAUST go AND CONDENSATESTEAM SYSTEMAs the boiler heats up the water that generates steam, the steam travels at a very high pressure through various valves, a low pressure turbine, and is then exhausted into the condenser. The valves are used to maintain a set pressure in new(prenominal) to protect most of the steam components which is used to rotate the turbine. The stop valve is used to stop the steam as it flows into the turbine in case of any problem that could damage the turbine.The check valve is used to control the amount of steam which flows into the turbine thereby controls the speed of the turbine when it is connected to the grid used to generate electricity by the help of an prone generator.CONDENSATEThe final place for the steam that is produced in the boiler is the condenser. In the condenser, the steam turns back into water by means of a heat exchanger which condenses the steam into liquid by cooling.EXHAUST STEAM The exhaust steam is used to release the steam that no longer has enough heat energy after it ha s being used.BLOW-DOWN SYSTEMDuring the process of the steam generated, if any impurity carry over with the steam it would cause overheating in the superheater tubes. The blowdown system is used to prevent deposit of impurities into other surface handle the turbine blades.DISCUSSIONSWhat did you learn about the equipment or technique?In this lab experiment, I have learnt about the quintuplet major external components of a gas fired boiler. How each stages is essential for generating steam. It is important to thoroughly witness the need for boiler to generate steam can also be catastrophic when no comme il faut care is put in place.What problems were encountered? The few problems that could be encountered are as followIf there is no safety valves installed on top of the boiler to protect the steam system components from over pressure,As fuel enters through the main fuel line, the valves that allow for easy shut-off of fuel flow to the boiler is broken causation fuel leakage that could cause fire outbreak.How this equipment or technique could be applied to chemical toil?In chemical production, the equipment or technique could be applied to chemical production for the following reasonsAs water heats up and converts to steam, the steam is used to power or rotate the blades of the turbines for generating electric which provides the voltage and authoritative used to power other electrical equipment for the chemical production.The steam could be used for processing chemical products by means of sterilization.The steam could be used to power heating and air conditioning units in the chemical production plant.CONCLUSIONThe Process flow and P ID diagram gave me the opportunities to have a broader discretion a boiler system and how each components work to generate steam.REFERENCESBoiler power generation.
