Tsari mai yawa da abu mai sauƙi ya yi aiki shi ne tsari mai yawa da kuma ita ce ta fahimta. Abu mai sauƙi shi ne wani tasa mai sauki da ake magance ruwan a cikinta. An yi hoton kayan adam (kawai annabi) a wurin da anke bayarwa da kuma an yi kayan jiki.
Kayan jiki na biyu suka shiga tasa mai ruwan inda heat na kayan jiki na biyu suka zama ruwan da kuma ruwan ya zama a abu mai sauƙi.
Sannan ruwan ya zama tun daga abu mai sauƙi zuwa turbine na thermal power plant. Akwai ƙarin abubuwa types of boiler da ake amfani da su don ƙarin abubuwa kamar running a production unit, sanitizing some area, sterilizing equipment, to warm up the surroundings etc.
Yawan karfafi na total heat exported by outlet steam in the total heat supplied by the fuel (coal) is called steam boiler efficiency.
It includes with thermal efficiency, combustion efficiency and fuel to steam efficiency. Steam boiler efficiency depends upon the size of boiler used. A typical efficiency of steam boiler is 80% to 88%.
Actually there are some losses occur like incomplete combustion, radiating loss occurs from steam boiler surrounding wall, defective combustion gas etc. Hence, efficiency of steam boiler gives this result.
Akawo ɗaya na abubuwa na abu mai sauƙi - water tube boiler da fire tube boiler.
A fire tube boiler, akawo ɗaya na tubu da ake shiga kayan jiki na biyu, sannan ruwan ke nuna wa tubu.
Water tube boiler shi ne tsari na biyu da fire tube boiler. A water tube boiler, ruwan ke sauƙe a cikin tubu, sannan kayan jiki na biyu ke nuna wa tubu.
Wadannan ne abubuwa na biyu na abu mai sauƙi, amma har zuwa da duka zai iya gajarta a ƙarin abubuwa da zan iya hada da shi a baya.
Idan ake kiran sunan, fire tube boiler na ni akawo ɗaya na tubu da ake shiga kayan jiki na biyu. Wadannan tubu na kayan jiki na biyu suka shiga ruwan, a tasa mai sauki.
Akwai ɗaya na tasa mai sauki ko shell da ke nuna ruwan, inda tubu na kayan jiki na biyu suka shiga.
Wadannan tubu na kayan jiki na biyu suka sauƙe ruwan da kuma zama ruwan, sannan ruwan ya zama a cikin tasa na biyu.
Saboda ruwan da ruwan su a cikin tasa na biyu, fire tube boiler ba zan iya sauya ruwan da take da takaitaccen pressure ba.
Amma ya kamata ya sauya ruwan da take da takaitaccen 17.5 kg/cm2 da capacity na 9 Metric Ton of steam per hour.
Akawo ɗaya na fire tube boiler kamar, external furnace and internal furnace fire tube boiler.
External furnace boiler can be again categorized into three different types-
Horizontal Return Tubular Boiler.
Short Fire Box Boiler.
Compact Boiler.
Sannan, internal furnace fire tube boiler na ni ƙarin abubuwa kamar horizontal tubular and vertical tubular fire tube boiler.
Gaskiya horizontal return fire tube boiler na amfani a thermal power plant na low capacity. It consists of a horizontal drum into which there are numbers of horizontal tubes. These tubes are submerged in water.
An yi hoton kayan adam (kawai annabi) a kan horizontal drum, sannan kayan jiki na biyu suka shiga a kan rear, inda suke shiga a fire tubes and travel towards the front into the smoke box.
A lokacin nan, kayan jiki na biyu suka bayar heat zuwa ruwan, da kuma bubbles na ruwan suka shiga. Idan ruwan ya zama, pressure na abu mai sauƙi ya faru, a cikin tasa mai sauki.
Muhimmanci na fire tube boilers include—
It is quite compact in construction.
Fluctuation of steam demand can be met easily.
It is also quite cheap.
Abin da ba su da muhimmanci na fire tube boilers include—
As the water required for operation of the boiler is quite large, it requires long time for rising steam at desired pressure.
