Introduction

CEEN1997 A.D(CEE)Non governmental and non profit making org Alternative energy sector – specialized in biomass

energy2009 A.D (CEEN)Prof Dr. Krishna Raj Shrestha - BHB -1997Promoted through CEE

Objectives

• To undertake adaptive research/impact study• To implement programs for sustainable

utilization • To empower women through capacity building

and transfer of technology• To mobilize and institutionalize rural

communities and provide technical supports and consultancy service to achieve above objectives.

Activities/Service

• Laboratory services for biomass/fuel and stove• Training on biomass and charcoal briquetting; designing of

molds, briquetting machine• Designing and testing of various combustion devices for

space heating and cooking• Gender sensitization and income generating activities for

women• Providing support- project/ dissertation of student

researchers• Interaction/orientation – interested crowd – students

Fabrication of stoves

Institutional low cost stove Perforated burner with blower

Clay lined stove with chimney

Gasifier stove

Agni stove Low cost can stove

Some of the dissertations

M.Sc. Thesis on briquetting unit - IOE

M.Sc. Thesis on stove testing- IOE

B.Sc. Project work on different raw materials

for briquetting- KU

Biomass laboratory and stove performance testing facility in CEEN

Adiabatic calorimeter, Analytical balance Muffle furnace, Drying oven

Equipments/facilities• Hodaka emission analyzer•Fluke Digital thermometer (dual)•Fluke Carbon Monoxide meter•Hoiki data logger•IR temp recorder•Pulveriser•Grinder•Hammer mill•Moisture meter• Digital thermocouple•Bacharach smoke pump•Drying oven•Muffle furnace•Spray welding facilityMuffle furnace

Testing methodology for briquette fueled stove at CEEN laboratory

Why not other contemporary methods available in market?

• WBT designed specially for wood fuel burning stovesDifficulties during experimentation

Difficult to extinguish, separate charcoal – direct densified briquette

Difficult to extinguish the carbonized briquette – beehive briquettes

Difference as fuel with respect to firewood

• Density of briquette = 2 X density of common fuel wood

• Porosity - very low • Briquette Char from combustion > denser than

wood or biomass charcoal• SPB > combustibility RPB

Where in the world??

• Japan - Kim H., kazuhiko and masayoshi S., “Bio-coal briquette as a technology for desulphurizing and energy saving”, In T. Yamada ed. Chapter34, 2001, 33-75

• Department of Management and Engineering ,Modified Water Boiling Test : Biomass Briquettes in Malawi

• Thailand -Renewable Energy Technologies in Asia: A Regional Research and Dissemination Program Phase II

Development and Dissemination of Improved Biomass Briquetting Systems and Cooking Devices , Asian Institute of Technology (AIT)

• India- Vinita Bharti & Mamta Awasthi ,Pine Needle Charcoal Briquettes: Rural Technology Option In Pine Forest Region,

Difference

High power test with hot start and shimmering test

Instruments

• Toshniwal Digital Bomb calorimeter with software Model no CC01/M2A

• Digital balance capacity 30 kg• Dual input Digital thermometer with Fluke

view software. Model no 54IIB• Timer • Wooden fixture for holding the probe• Utensil to boil water

Pre test jobs

• Well dried , uniform size• Kindles prepared ahead , pre weighted• Stabilization and familiarization- fuel wt,

water, vessel• Determination of LBP• Proper ventilation - no breeze • CV, moisture, specific heat of water, latent

heat of evaporation of water

Strength

• Simple and replicable• Preliminary understanding of stove

performance

Weakness

• Rough approximation of how efficiently the stove performs

• Controlled condition

Issues related to lab and field test

• No standard methodology for Briquette fueled stove

• Refresher trainings for Researchers• Accreditation• Occupational Health and Safety measure of

researcher

Our clients?

• Students – Masters, Bachelors thesis• Industry - Briquette entrepreneurs Stove manufacturers • Other organizations
