Steam Losses

Heat Balance
Heat balance is an attempt to balance the total energy that enters a boiler against the energy that leaves it.

Tujuan:
improve energy efficiency by reducing avoidable losses

Gambar berikut menunjukkan bagaimana energi diubah dari fuel menjadi useful Energy, Heat dan Losses.



Losses yang dapat dihindari:
- Stack gas losses (excess air, stack gas temperature)
Excess air (reduce to the necessary minimum which depends from burner technology, operation, operation (i.e. control) and maintenance) and Stack gas temperature (reduce by optimizing maintenance (cleaning), load; better burner and boiler technology).

- Losses by unburnt fuel
better technology of burner.

- Blow down losses
treat fresh feed water, recycle condensate.

- Condensate losses
recover the largest possible amount of condensate.

- Convection and radiation
reduced by better insulation of the boiler.

Gambar berikut menunjukkan Losses yang terjadi:



Panas / Heat yang ada hanya sekitar 73,8% yang dapat dipakai, untuk itu dibutuhkan Heat Balance untuk meminimalisir Losses yang terjadi.
