Once-through boiler

A once-through boiler is a boiler without recirculation
where water flows through the economizer, furnace wall,and evaporating and superheating tubes, sequentially.
Once-through boiler is used to supply heat in factory andcommercial facility.

Periodical check

Periodical check is a scheduled examination of the project
boiler conducted by manufacturer or agent who isauthorized by the manufacturer in order to maintainperformance of the boiler.

Boiler efficiency

Boiler efficiency is the percentage of heat quantity used togenerate steam against total heat quantity provided by afuel.

Fuel switching

Fuel switching involves the change of boiler fuel from theone with higher CO2 emissions factor to lower CO2
emission factor (i.e. from coal to natural gas).

Summary
reduction This methodology involves the installation of high efficiency
once-through boiler. Compared with the water tube boilers andfire tube boilers which dominate Myanmar market, theefficiency of once-through boiler is higher and fuelconsumption is less. Thus the introduction of once-throughboiler will contribute to the GHG emission reductions.

Calculationofreference Reference emissions are calculated based on the efficiency of2

emissionsthe boiler currently dominant in the Myanmar market.
Conservative estimation of reference emissions is made bytaking the following points into consideration: (i) lower CO2
emission factor is selected from IPCC guideline with regard to
the fuel used in reference boiler, and (ii) higher efficiency isapplied for the reference boiler especially in low load range.

D. Eligibility criteria

This methodology is applicable to projects that satisfy all of the following criteria.
Criterion 1Criterion 2

The project boiler is a once-through boiler with a rated capacity of 7 ton/hour
per unit or less (equivalent evaporation)
Periodical check and maintenance by the manufacturer of boiler or authorized
agent is implemented at least once a year.

F. Establishment and calculation of reference emissions
F.1. Establishment of reference emissions
Reference emissions are calculated based on the efficiency of the water tube and fire tubeboilers which dominate the boiler market for industries in Myanmar. The fuel types widelyused in Myanmar are oil, followed by coal. Natural gas is mainly used in power sector and not3

JCM_MM_F_PM_ver01.0

distributed to private industry sector.
In order to ensure net emission reductions, a higher efficiency of the reference boiler (89%) isadopted to calculate the reference emissions. In addition, 1) compared with reference boiler(oil and gas type), once-through boiler (project boiler, oil and gas type) can maintain highefficiency even at low load range, which improves the operating efficiency of project boiler,and 2) compared with reference boiler (coal), operational efficiency of the project boiler ishigher due to better combustion control, which also ensures the net emission reductions. Inaddition, to calculate the reference emission conservatively, lower emission factor stated in2006 IPCC guidelines is adopted to secure the net emission reductions.
