COMPUTATIONAL ANALYSIS OF PULVERIZED COAL CO-FIRING WITH BIOMASS IN 150MWe UNIT OF TUNCBILEK THERMAL POWER PLANT

Öz:
Pulverized coal and biomass co-firing in the 150MWe unit of Tuncbilek power plant is computationally investigated, within the scope of a preliminary feasibility study. The considered furnace, burning Turkish lignite, has totally eighteen burners, positioned at three different levels. First, the pulverized coal combustion in the furnace is calculated and the predicted temperatures in the boiler first pass are compared with the previous measurements. Subsequently, a co-firing scenario is computationally analyzed, where the burners of the lowest level that supply 43% of the total fuel mass are fed by biomass, instead of coal. Turkish red pine is assumed to be the source of the biomass. In replacing the coal by biomass, the mass flow rates of the biomass and the corresponding air are adjusted in such a way that the thermal load and the equivalence ratio remain unaltered. Due to the lack of more accurate data for the biomass, the rate constants for the pyrolysis and chemical conversion of biomass are assumed to be the same as those of coal, along with the assumption of the same particle size distribution for both fuels. It is observed that the resulting flame structure for the case of co-firing is very similar to that of coal combustion. This result is encouraging for the application of biomass co-firing in the considered furnace.

TUNҪBİLEK TERMİK SANTRALİNİN 150MWe ÜNİTESİNDE PÜLVERİZE KÖMÜRÜN BİYOKÜTLE İLE EŞ YANMASININ HESAPLAMALI ANALİZİ

Öz:
Pülverize kömür ve biyokütlenin birlikte yanması Tunçbilek termik santralinin 150MWe kapasitesindeki ünitesi için, bir ön fizibilite ҫalışması kapsamında, sayısal olarak incelenmiştir. Türk linyit kömürü yakmakta olan söz konusu fırın, üҫ seviyeye yerleştirilmiş toplam on sekiz brülörden beslenmektedir. İlk olarak, fırında pülverize kömür yanması hesaplanmış ve kazan birinci geҫis kanalı içinde bulunan sıcaklıklar daha önceki ölҫümlerle karşılaştırılmıştır. Akabinde, toplam yakıt kütlesinin %43‘ünü sağlayan en alt seviyedeki brülörlerden, kömür yerine biyokütle gönderilmesini öngören bir eş yanma senaryosu hesaplamalı olarak analiz edilmiştir. Türk kızıl ҫamı biyokütle kaynağı olarak kabul edilmiştir. Kömürü, biyokütle yakıtı ile değiştirirken, biyokütle ve hava debileri termik güҫ ve hava fazlalık katsayısının sabit kalacağı şekilde ayarlanmıştır. Her iki yakıt iҫin de aynı partikül büyüklük dağılımı kabul edilirken, elde daha hassas bilgi olmamasından dolayı, biyokütlenin piroliz ve kimyasal dönüşümü ile ilgili hız sabitlerinin, kömür iҫin kullanılanlar ile aynı olduğu kabul edilmiştir. Birlikte yanma durumunda elde edilen alev yapısının kömür yanmasınınkine ҫok benzer olduğu gözlemlenmiştir. Bu netice, incelenen kazanda biyokütlenin kömür ile birlikte yanmasını teşvik edici niteliktedir.
