Definitions

Drain

Drain is a waste hot water which is trapped and condensed
after waste steam at process of works is caught by steam trap.

Closed drain recovery

Drain recovery system is an equipment which recovers drain

systemwith some heating energy and reuses for boiler feed water.
Recovered drain is once stocked in tank before reuse. Closed
drain recovery system has a tank with the lid. Drained water is
kept at high temperature.

Opening drain recovery

Opening drain recovery system has a tank without covering.

systemTemperature of drained water is down to 100 ºC or lessbecause vapor of drained water is released to atmosphere.

Summary
reduction By installing a closed drain recovery system, boiler feed water
is heated up. Consequently, fossil fuel consumption of boiler(s)is reduced, leading to the reduction of GHG emissions.

Calculation
emissions

ofreference Reference emissions are calculated using the following
parameters:
・ Saving rate of boiler fuel consumption per degree of risen
temperature for boiler feed water・ Temperature of boiler feed water including both of makeup
feed water and hot water recovered by the project closed
drain recovery system
・ Reference temperature of boiler feed water including bothof makeup feed water and hot water recovered by theproject closed drain recovery system

recovered by the project closed drain recovery system
・ Net calorific value of fossil fuel consumed by boiler(s)・ CO2 emission factor of fossil fuel consumed by boiler(s)Calculationofproject Project emissions are not considered as a project closed drainemissions

Monitoring parameters

・ Amount of the fossil fuel type consumed by boiler(s)utilizing hot water recovered by the project closed drain

In this methodology, it is assumed that opening drain recovery system is set as the reference
one, because in many factories in Indonesia, drain recovery system is not introduced or opening
drain recovery system is applied. In case that an opening drain system is introduced, thetemperature of recovered drain water is comparatively low, and the amount of boiler fuel isneeded more than the case when a closed drain recover system is introduced.
In order to secure net emission reductions in this methodology, the reference emission isconservatively calculated in the following manners.
-Setting “temperature of makeup feed water into boiler(s)” as 30.3 oC based on the highest
value in the monthly average atmospheric temperatures for 2 years (November, 2018- October,2020) in Jakarta, Medan, Palembang, Balikpapan, Semarang, Denpasar, Cirebon, Serang,Tegal, Cilacap and Curag.
-Setting “Rate of decrease in boiler fuel consumption per degree rise in temperature of boiler
feed water” as 0.0015 [dimensionless /K] in case that boiler feed water is 20 ºC. The savingrate at the temperature range of boiler feed water higher than 20 ºC is slightly higher than
0.0015 [dimensionless /K].
-Setting “reference temperature of boiler feed water including both of makeup feed waterand hot water recovered by a project closed drain recovery system” as 100 [ºC].

Project emissions are not assumed in the methodology as a project closed drain recovery systemdoes not utilize electricity and any fossil fuels, which is prescribed in the eligibility criterion 2.
Therefore, the following formula is used to express the project emissions:
𝑃𝐸𝑝 =0
