RETS is continuously enhancing it’s capacity in quality assurance of solar thermal products.


RETS BIOMASS LABORATORY RETS initiated ICS testing from , June 2012

Network Partners

AEPC/ESAP, RETS and NAST

Protocol used:-

Interim National Standard Stove

Testing Protocol of Energy Sector Assistance

Program (ESAP)/AEPC (developed by

STARIC Nepal)

(It includes data entry MS excel sheet to

calculate efficiency through Water Boiling

Test (WBT)) This protocol follow Aprovecho’s Stove

Performance Testing Protocol Published

by Aprovecho Research Centre, USA

(WBT version 3.0)National Workshop on Stove Testing Standards in Nepal , 25th July 2013

Technical Officers from AEPC, NAST & RETS ( 6 members) has successfully completed training on PEMS (Portable Emission Monitoring System) in January ,2013 at RETS

Organized by AEPC ,NAST / RETS with support of Nepal Energy Efficiency Programme (NEEP) of GIZ.

With installation of PEMS , emission testing of cooking stove is possible at RETS.

Emission Testing Activity


WHAT IS PEMS?

Portable Emission Monitoring SystemThe purpose of the PEMS is to quantify reductions in health-harming emissions from cooking stoves by collecting, measuring, and analyzing emissions of CO2, CO, and PM.

It RecordsCO Concentration (ppm)CO2 Concentration (ppm)PM Concentration (µg/m3)Exhaust Gas Temperature (ºc)Water Temperature of Pot (ºc)


Emission Sensors used

CO sensor /Co2 sensor /PM sensor

Software Included

Microsoft Excel Compatible Data Processing Software

Outputs include: Total Emissions

Specific Emissions

Emission Factors

Fuel Consumption and Efficiency

Live Graph for graphing the output in real time

Terreterm serial port communication software

Protocol used for calculation of result:-WBT version 4.2.2 (Aprovecho research Centre)

Water Boiling Test (WBT) data calculation sheet v. 4.2.2 (excel)


SPECIFIC FEATURE OF PEMS

Portable (only 23 kg) (Power required 250 Watt)

This equipment can be used in lab as well as in field

Easy to install anywhere in field & lab because of flexible hood structure

PRESENT STATUS /FUTURE PLAN OF BIOMASS LABORATORY

Present Status5 models of ICS received from of AEPC have been tested (WBT) and reported.One model of KU & one model of Greenway India have been tested Using PEMS (WBT & emission)Contract ready for signing with SNV/Nepal for field testing of ICS using PEMS in Dadeldhura districtCoordination with AEPC for testing and certifying of ICS under NRREP.


FUTURE PLAN Laboratory upgrading by installation of LEMS and IAP

(indoor air pollution) meter (Financial assistance from NRREP/AEPC)

Field monitoring & Testing of ICS in various districts. Lot verification of ICS at the Manufacturer’s

warehouse before dissemination Preparing Business plan of Biomass laboratory with

support from AEPC Benchmark fixing for the minimum quality of ICS

AEPC/RETS Accreditation of the laboratory from NBSM (Process

initiated) Recruitment of addition al human resources as per

need. R & D activities at NAST Govt. Funding through NAST
