3.08% ammiak tutgan gazni kalonnaga kirishdagi xarorati 36℃va entalpiyasi i₁=4160 kj/kg ga teng. Kalonnaga kirishda issiqlik almashgichdan o’tadi va jarayonda gazlarni xarorati 9℃ ga ko’tariladi shunga ko’ra 45 ℃ dagi gaz entalpiyasi i₂=4190 kj/kg ga teng. Vaqt o’tishi bilan 2-teploobmenikdan 3-teploobmenikgacha 7 ℃ ga ortadi. Shunga ko’ra 52 ℃ gaz entalpiyasi i₃=4210 kj/kg ga teng.

1. 
   Gaz aralashmasi entalpiyasi
   

i₂ – i₁ = 4190 – 4160 = 30 kJ/kg

2. 
   Katalizator qutisida ajralgan issiqlik.
   

i₇ – i₃ = (i₂ – i₁) + (i₇ – i₄)
Bu yerda i₇ ni qisqartirib i₄ ni topamiz
i₄= i₉ + i₂ – i₁
i₄ = 5000 + 4190 – 4160 = 5030 kJ/kg
i₉-katalizator qutisidan chiqayotgan 18.04% ammiak tutgan 480℃ li gaz entalpiyasi i₉=5000 kj/kg ga teng.

3. 
   Katalizator qatlamiga kirayotgan 3.08% ammiak tutgan 480℃ li gaz entalpiyasi i₇=5580 kj/kg ga teng. Reaksiya natijasida chiqadigan issiqlik.
   

i₇ – i₉ = 5580 – 5000 = 580 kJ/kg

4. 
   Teploobmenikdagi gaz xarorati 52℃va entalpiyasi i₃=4210 kj/kg ga teng. Teploobmenikdan chiqishda gaz xarorati 284℃va entalpiyasi i₄=5030 kj/kg ga teng. Gaz issiqlik almashinish apparatidan qabul qiladigan issiqlik
   

i₄ – i₃ = 5030 – 4210 = 820 kJ/kg
Bundan tashqari issiqlik almashinish apparati tirqichidan beriladi
i₃ – i₂ = 4210 – 4190 = 20 kJ/kg

5. 
   Issiq gaz sovushi natijasida sovuq gaz yutadigan issiqlik
   

i₄ – i₂ = 5030 – 4190 = 840 kJ/kg

6. 
   Issiq gaz beradigan issiqlik (atrof-muhitga yo`qotilish hisobga olinmaydi)
   

i₄ – i₂ = i₁₀ – i₁₁ = 840 kJ/kg

7. 
   Issiqlik almashinish apparatiga kirayotgan issiq gaz uchun
   

i₁₀ = i₁₁ + 840 = 3680 + 840 = 4520 kJ/kg

8. 
   Issiqlik miqdori farqi
   

i₉ – i₁₀ = 5000 – 4520 = 480 kJ/kg

9. 
   Umumiy issiqlik miqdori.
   

Q₁₃ – Q₁₂ = m₁₂ (i₁₃ – i₁₂ )= Q₉ – Q₁₀ = m₉ (i₉ – i₁₀) = 65076 · 480 = 31236480 kJ/kg
i₁₃ – i₁₂ = 1234,5 – 945,8 = 288,7 kJ/kg]
i₁₃ - 280℃ dagi suv ntalpiyasi i₁₃=1234.5 kj/kg
i₁₂ - 220℃ dagi suv entalpiyasi i₁₂=945.8 kj/kg
Shunday qilib isitilgan suv massasi
