Study Report
Description of Project/ActivityThe Project/Activity is to upgrade inefficient boilers to the latest efficient boilers or to newly install the latest boilers. The target facility is a boiler dedicated to heat supply (HOB) with a capacity of "0.10 to 3.15 MW" based on the Mongolian standard (MNS5043). The improved boilers consume less coal for HOBs and, as a result, reduce the emissions of greenhouse gases (GHG).
Eligibility CriteriaCase 1: The project activity is to
    - switch from old type coal HOBs (of low energy efficiency) to new type ones (of high energy efficiency) in existing Heat Water Supply Systems in Districts and/or
    - to introduce new type ones in association with new construction of Heat Water Supply Systems in Districts.
    (Upgrading or installation of HOBs for steam supply do not fall into the project/ activity)

Case 2: The HOB to be targeted for the Project/Activity is defined as a boiler used for heat supply which has capacity of 0.10MW – 3.15MW.

Case 3: Objective HOBs are limited to coal-fired boilers for hot water supply.

Case 4: The HOBs to be introduced shall have the performance specifications including the boiler efficiency higher than 75% as the manufacturer’s catalog value.

Case 5: The HOBs to be introduced shall have a dust collector. In case of a HOB which dust collector is not set up, dust collector shall be additionally installed with the installed HOB for pollution-abatement measure.
Reference Scenario and Project/Activity BoundaryIn the reference scenario, the low-energy-efficiency old HOBs will be continuously used even after upgrading if no foreign aid can be obtained and, in the case of the construction of new systems, the same-type boilers will be introduced as those for the upgrading if no foreign aid can be obtained. The same benchmark value for the boiler efficiency in the reference scenario will be adopted for both the upgrading and the new installation.

In the reference scenario, the Project/Activity Boundary is the CO2 emissions concerning the coal consumption at the boilers. In the Project, the Boundary is the CO2 emissions concerning the coal consumption and electricity consumption at the boiler. The other GHGs and their emission sources are excluded from the items to be calculated due to simplification, to secure the conservativeness and their slight amounts.
Calculation Method OptionsThe calculation method option is:
GHG emission reductions amount = (1/boiler efficiency of reference boiler-1/boiler efficiency of project boiler) * heat amount supplied to buildings * emission factor,
and the Monitoring Methods for the heat amount supplied to buildings are classified as follows:

Monitoring Method 1-1: Heat meter
Directly measure the heat amount supplied to the buildings using a heat meter.

Monitoring Method 1-2: Calculation using a flow meter and thermomete
Obtain the heat amount supplied to the buildings by calculation using the measurements of the temperature of the heat water supplied to the project HOB (inlet), the temperature of the circulating water supplied by the project HOB (outlet), and the Volume flow rate of the circulating water of the project HOB.

Monitoring Method 2-1: Preliminary flow measurement
Estimate the heat amounts supplied to the buildings using the temperature of the heat water supplied to the project HOB (inlet) and the temperature of the circulating water supplied by the project HOB (outlet), which are measured on the pipe surfaces and the flow, which is the minimal value of those measured in advance for one week.

Monitoring Method 2-2: The rated pump capacity
Estimate the heat amount supplied to the buildings using the temperature of the hot water entering and the temperature of the hot water exiting, which are measured on the pipe surfaces and the flow, which is the pump capacity.

Monitoring Method 3-1: Specific value of the building specific heat loss coefficient
Estimate the heat amount supplied to the buildings using the building volume, the outdoor temperature, and the indoor temperature. The building specific heat loss coefficient is a specific value for the project.

Monitoring Method 3-2: The heat loss coefficient for the building in the supply destination is default value.
This option is almost the same as Monitoring Method 3-1 and the building specific heat loss coefficient is the default value.
Default Values set in MethodologyDefault Value
Project Boiler Efficiency: 67% (set based on the study by actual measurement)

Reference Scenario Boiler Efficiency: 50% (the result of the study by actual measurement is 44%. Since the reference scenario should become more conservative than BaU scenario, the boiler efficiency of the reference scenario is set up to 50%. )
CO2 emission factor: 0.096tCO2/GJ: according to the averages value of 17 sampling surveys based on laboratory analysis of the consumed coal.

Heat Loss Coefficient for the Building in the supply destination: 0.20: This value is conservatively set based on the values of 79 schools with high heat insulating effects.
Discount Rate obtained When the "Heat Loss Coefficient for the Building in the supply destination" is used: 20%. This value was set based on the study by actual measurement so that ore than 95% of the estimated value should be more conservative than actual values.

Project-Specific Values
Heat Loss Coefficient for the Building in the supply destination: Design value of each building

Pump Capacity: Name plate of the pump
Required electric performance maximum of the project HOB according to the Manufacturer's manual value
Monitoring MethodMonitoring activity was implemented. The following two options will be described.

Monitoring Method 1-1:
Directly measure the heat amount supplied to the buildings using the heat meter. The monitoring parameter was the heat amount supplied and it was continuously measured and recorded in every hour.

Monitoring Method 3-1:
Estimate the heat amount supplied to the buildings using the building volume, the outdoor temperature, and the indoor temperature. Also, enable acquisition of the specific value of the building specific heat loss coefficient. The outdoor temperature and the indoor temperature are monitored, and continuously measured and recorded in every hour.
Result of Monitoring ActivityThe two options according to which the monitoring activity was implemented will be described.

For Monitoring Method 1-1, a monitoring plan was formulated, monitoring was implemented, and a monitoring report was produced according to the monitoring plan.

The data collection and the data analysis for making default values were required in the Monitoring method 3-1. Then, the Monitoring Plan was reconstructed, and the Monitoring Report was made according to the Monitoring Plan.
GHG Emissions and its ReductionsMonitoring method 1-1: 1tCO2/t (t=201[hour])

Monitoring method 3-1: 2tCO2/t (t=443[hour])

Since the monitoring time is very short and the values are rounded up and rounded down for the purpose of the conservativeness, the values of GHG Emission Reduction are still smaller.
Based on the annual operating time of the HOB, which is 5000 to 6000 hours, the annual emission reductions are estimated to be about 100 tCO2/yr.
Method and Result of VerificationFor Monitoring Method 1-1, verification was implemented on the monitoring report and a verification report was produced. As a result, the MRV activity was practically verified in Mongolia.

Verification activities were difficult for the monitoring method 3-1. However, the default values of the discount rate were set up from the actual measurement, and the verification activities were limited only with the monitoring data of thermometers. As a result, the verification activities were implemented.
Environmental ImpactsThe coal consumption was also reduced through the Project/Activity and, therefore, no adverse influence on the environment is especially observed.
Promotion of Japanese TechnologyThe policies are advanced including the one to consolidate the HOBs and the possibility of introducing Japanese technology in the future is getting higher.
Sustainable Development in Host CountryThe effect of reducing air pollution on human health is estimated to correspond to US$ 12 million. The policies are advanced including the one to consolidate the HOBs and the Project/Activity match the development policy and the development strategy of the host country.
