Abstract:

 The cold flow and flame characteristics of liquefied petroleum gas LPG- mixing 70 butane and 30 propane in a household stove are experimentally investigated. The household stove has three cookers with rectangular ports and different sizes. The flame temperature and gas flow velocity are measured at maximum and minimum flow rates under laboratory conditions. Temperatures in the horizontal, vertical, and diagonal directions are measured at a distance between the reference point and 3 cm. The temperatures between the maximum and minimum flow rates show significant differences for all cookers. Flame temperatures at the gas exit point are 620710 C at the maximum gas flow rate. On the largest cooker, the gas emissions in the diagonal direction at the maximum flow rate are also measured. The maximum value of CO emissions 7000 ppm is measured at the reference point. CO2 emissions are 12 between the reference point and 1.5 cm and slightly decreasing to 11 at other points. NOx measurements ppm show a peak value of 180 ppm at the 0.5 cm point. Cooker 1 is in the turbulence regime at maximum flow rate, while the other cookers are in the laminar regime.

 Bir ev tipi ocakta sıvılaştırılmış petrol gazının 70 butan ve 30 propan karışımlı soğuk akış ve alev karakteristikleri deneysel olarak incelenmiştir. Ev tipi ocak, gaz çıkışı dikdörtgen kesitli farklı büyüklüklerdeki ocaklardan oluşmaktadır. Maksimum ve minimum gaz akış debisinde, alev sıcaklığı ve gaz akış hızları laboratuvar şartlarında ölçülmüştür. Sıcaklıklar yatay, dikey ve diagonal doğrultularda ve referans noktası ile 3 cm arasındaki mesafelerde ölçülmüştür. Maksimum ve minimum debilerdeki sıcaklıklar, tüm ocaklarda önemli farklılıklar göstermiştir. Maksimum debide, gaz çıkış noktasındaki sıcaklıklar 620710 C arasındadır. En büyük ocakta, maksimum debide diagonal yönde gaz yayınımları da ölçülmüştür. COin maksimum değeri referans noktasında 7000 ppm olarak tespit edilmiştir. CO2 yayınımı referans noktası ile 1.5 cm arasında 12 olup, diğer noktalarda yavaşca 11 e azalmaktadır. NOx ölçümleri 0.5 cm noktasında 180 ppm ile maksimum değeri göstermiştir. Ocak 1 maksimum debide türbülanslı akışa sahip iken, diğer ocaklar laminer akış rejimine sahiptirler.
