Gasoyi na samun kisa suna da mafi yawan nitrogen, carbon dioxide, wadannan ruwan, soot, carbon monoxide, kuma wasu abubuwa.

Saboda haka, economiser a cikin ilimin girmama tana amfani da ita don iya koyar da tattalin aiki na girmama, kamar yadda sunan karamin abinci yana nuna. Tsari da aka hauƙa za a yi amfani da shi don haɗa ruwan da ke kisa mai girma, wanda ya zama steam mai girma a tsaye. Wannan tana taimakawa wajen tabbatar da adadin kayan gwamna da tana bukata da koyar da tattalin aiki. A lokacin da yanzu, ba amsa wannan, tsari da aka hauƙa a cikin gasoyi na samun kisa tana iya haɗa da abinci mai kyau a cikin air pre-heater, wanda ke na muhimmanci a cikin duk kisa mai girma da ake girmanta da coal.

Prinsipi Na Ƙiyasin Kudin Aiki

Kamar yadda aka baka a cikin hoton, gasoyi na samun kisa da suka fito daga kisa mai girma suna da mafi yawan tsari. Farkon economiser a cikin ilimin girmama shine haɗa wadannan tsari da suka hauƙar gasoyi na samun kisa kafin ake fito a ciki har zuwa wata, don hauƙar ruwan da ke kisa mai girma. Shi ne karamin abinci mai kyau da gasoyi na samun kisa a cikin tsari na farko da ruwan a cikin tsari na biyu, tare da fina-finai ko gills.

Economisers a cikin ilimin girmama tana da muhimmanci wajen inganta adadin gasoyi na samun kisa, ma'adadin tsari, yanayin fitowa a cikin stack, wani abu da ake amfani da shi a cikin kisa, da kuma adadin abinci da ke buƙata.

Idan ruwan ya girma a cikin kisa mai girma, steam an haɗa, wanda an yi amfani da shi don haɗa steam mai girma, kafin ake fito a cikin turbines. Steam da aka fito daga blades na turbine, an fito a cikin steam condenser na turbine, inda an haɗa steam, wanda an haɗa ruwan, an haɗa shi a feed water heater, kafin ake haɗa a cikin kisa.

An saukar shi a cikin hanyar gasoyi na samun kisa bayan kisa mai girma kafin ake fito a ciki har zuwa wata. A cikin wannan, akwai miliyan ruwan da suka fito a cikin headers. Gasoyi na samun kisa suna haɗa a cikin tubes, kafin ake haɗa a cikin counter flow.

Abubuwa D'Economise

CI Gilled Tube Economizer

Gilled tube economizers suna da cast iron, wanda suka yi amfani da graded cast iron fins, suna da muhimmanci:

• Mafi yawan kudin aiki saboda hanyar fina-finai da tubes.

• Amfani da shi a cikin plants idan gasoyi na samun kisa ana haɗa saboda abin da ake amfani da shi a cikin kisa.

Round Gilled Tube Economizer

Wannan an yi amfani da mild steel fabricated with square and round fins, welded on carbon steel seamless tubes, suna da muhimmanci:

Hanyar fina-finai da tubes tana da mafi yawan kudin aiki.

Coiled Tube Type Economizer

Wannan an amfani da shi a cikin ilimin girmama da processing units. Coiled tube type Economizers suna da carbon steel seamless, suna da muhimmanci:

• Sun taimakawa wajen haɗa abinci mai kyau daga gasoyi.

• Ba su da muhimmanci a kan space ba.

Horizontal Finned Tube Economizer

Wannan an yi amfani da carbon steel seamless tube sealed – welded with horizontal fins, suna da muhimmanci:

• Yana da mafi yawan kudin aiki saboda hanyar fina-finai da tubes.

• Amfani da shi a cikin ilimin girmama.

Non-Condensing vs. Condensing

Non-condensing economisers suna amfani da shi a cikin plants da ake amfani da coal don tabbatar da acid corrosion, idan kuma condensing economisers, wanda ake amfani da shi a cikin plants da ake amfani da natural gas, sun taimakawa wajen haɗa abinci mai kyau tare da hauƙar gasoyi na samun kisa a matsayin hanyar condensation point.

Amfani Da Fayawar Economizer

Akwai amfani da shi a cikin duk plants. Amfani da economizer tana taimakawa wajen koyar da adadin kayan gwamna, inganta rate na steaming, da kuma kudin aiki na kisa.

Wasu amfani da economizer:

• A cikin ilimin girmama, yana haɗa abinci mai samun kisa daga gasoyi na samun kisa (flue gases) kafin ake haɗa a cikin ruwan da ke kisa.

• Air-side economizers HVAC (Heating, Ventilation and Air Condition) sun taimakawa wajen koyar da kayan gwamna a cikin buildings tare da amfani da cool outside air don haɗa temperature a cikin buildings.

• Refrigeration: Wannan an amfani da shi a cikin refrigeration industry, idan ake amfani da vapor compression refrigeration. Systems da economizers sun taimakawa wajen haɗa abinci mai kyau a cikin pressures, inda compressors suna da mafi yawan kudin aiki.

Fayawa Da Abubuwan Economizer

Fayawar economizer sun haɗa:

• Yana haɗa abinci mai kyau daga gasoyi na samun kisa, wanda air pre-heater ba zan iya haɗa ba.

• Saboda increase in fuel prices, power plants suna da pressure don inganta kudin aiki na kisa. Don haka, amfani da economizer tana taimakawa wajen koyar da pressure na.

• A cikin power plants idan ba a amfani da economizer, an buƙata adadin ruwan mai yawa don haɗa gasoyi na samun kisa.

• Kafin ake amfani da economizers, yana taimakawa wajen koyar da adadin ruwan da ake buƙata.

• Kudin aiki na power plant tana rage idan steam air pre-heater an buƙata steam.
