Peko Pe

Paal Wendelobo was an absolutely dedicated champion of clean cooking stoves, and the people that rely on them.

From his son:
"For almost 30 years, Paal brought attention to health and environmental issues connected to cooking and household energy for development countries. Paal found other people, later friends, with similar ideas and thoughts in this stove community. Despite arguments about stove design, function, and whom had the better stove. No doubt he was a pioneer, teacher but also he was a student."
"His simple Peko Pe stove invited people think new. He was also a pioneer of TLUD stoves."

He died with family a few days ago, and we'll miss him.

Paal Wendelobo, October, 2011

The Peko Pe TLUD project in Zambia is going well.

Paal describes it best:

" The main principals for our projects I will call it community based participation both for fuel and for stove productions. Utilization of local resources with other words.. The Peko Pe is designed for production by local tinsmith with the tools they might have. They only need a template and a model; they have the knowledge how to make it.

" First of all we discuss the need of changes, and then on the fuel side we start up with registration of alternative biomass for fuel for briquetting, energy forestry for fuel production. We always start with the fuel .to be sure there is sufficient quantities and to an affordable price.

"The charcoal business, which represents about 15 % of the adult population, has to be involved from an early stage of the project. All kind of activities on the household energy sector will in one or another way have an influence of their business, and with biochar we don’t know what will happen, but that is one of the ting we will try to find out. Any how for the charcoal business it is just to change from charcoal to alternative biomass for household energy.

"The energy loss by production of biochar for soil improvement is almost equivalent to the energy needed for the farmer to cook if you include the African way of thinking time is coming not like by us time is running That is a big difference. A household need about 2,7 kg charcoal a day for cooking. Form about 10 kg of dry wood you will get 2,7 kg of charcoal for one day cooking and no biochar. From .10 kg of dry wood you will get 10 kg of woodchips and that will be for 2 ½ day of cooking into a TLUD-ND. and about 2.7 kg of biochar. The pilot project will tell us if this is right or wrong."

" A common Miombo forest in Africa will give about 3 ton wood per ha a year. 3 ton of dry wood will give 800 kg of charcoal. A household of 5 consume 2-3 kg charcoal a day or about 800 kg a year. To produce 3 kg of charcoal you need 10-12 kg of dry fire wood in a common kiln. That will give one day cooking on a charcoal stove, and almost no biochar. 10-12kg dry chopped wood will give 3 days of cooking on a TLUD-ND or another FES and 2.5 kg of biochar
Energy forestry using just the sprouting every year can give up to 10 ton wood per ha a year, easy to cut to appropriate fuel for TLUD-ND’s or other types of FES. By adding some biochar to soil of bad quality 20-30 % increased yields can be obtained, which will give more food, more household energy, more jobs, better economy, better health for women and children and saving the forest. It can probably be as simple as this and is that not some of what we are looking for and need?
We know some changes have to take place on the household energy sector and we have to start somewhere. Why not start with small scale farmers on sandy soil, and from there develop the new household bio-energy strategy for developing countries. Probably also with the charcoal business, they have the whole infrastructure intact and can easy change from charcoal to alternative biomass like chopped wood or pellets from agriculture and forestry related waste.

Clean burning PekoPe 2009Clean burning PekoPe 2009

The Peko Pe is an easy to built, top lit, natural draft (no fan) gasifying stove that burns biomass completely (low to no ash or char). It is

  • Efficient: easy to light, easy to handle, cooks quickly at high temperature.
  • Complete combustion no smoke and no soot
  • Flexible Covering all needs of energy for all types of household and institutional kitchen and other activities like take away food, bakery etc.
  • Simple Not intimidating technology.

The Peko Pe

The Energy Unit, single also called Peko Pe is designed to cover the general basic need for energy, but can be manufactured both smaller and bigger.

The combustion chamber is the heart of the system, and from there the heat will be consentrated up under the pot. The Energy Unit can be used both for cooking and for heating. Single, as a cooking or heating stove, it will cover the basic needs of energy for smaller household. More units put together will cover the need of energy for bigger houshold, institutional kitchen and pots of any size.

The fuel
Any kind of dry combustible biomass can be used as fuel.

The fire has complete combustion; is High temperature. No smoke. No soot. Some tar under the pan. Sensitive to wind

The usage
It is New technology and requires some training, but it is Easy to use; Flexible; Fits all types of kitchen utensils; and transmits No heat to the sides.

This report is in three parts: pioneer experiences; selection of photographs; and technical specifications of the PP stove. The report is based on e-mail interviews and materials provided by Paal Wendelbo in July 2008 and December to Paul S. Anderson, who has added interpretive content. Mr. Wendelbo has approved the basic content about himself, but Dr. Anderson is responsible for any errors, omissions, and editing.

Peko Pe 3 Liter Test Stove and Fuels
Paal Wendelbo, August 20, 2008
Boiling TestBoiling Test
The Multifuel Combustion System (MFCS) is a flexible system designed for bioenergy household and institutional cooking. It is based on one energy unit (the Peko Pe) which single or multiple will cower all needs of energy for inside and outside cooking. The energy unit has to be seen as a “battery” loaded with energy, and when empty, replaced with a new loaded until the food is ready. Two units of 3 litres will cover the needs of a family, ½ full with fuel for coffee or tea, a bit more for porridge and 1 ½ for the whole meal. For boiling beans, empty the unit and place the pot on the glowing char. A simple handle to hold the pot for mingling the enchima will be a good help. (See the drawing). For institutional cooking more 10litre units will be the best 3 Units will boil 60 litres within 50 minutes and continue boiling 2 more hours on 6kg of chopped wood-sticks. The system can be used for heating air or water, frying, cooking and baking bread, even smoking fish.

The MFCS will be faced the same problems as other type of new stoves and has to be trained, it is boiling faster and saving fuel (saving 2/3), burning with no smoke and little soot (depending a bit on type of fuel)
The system has been working for about 15 years and plans or more information is available by paaw@online.no

Attached you will find some pictures of a simple 3litre teststove I use to test types of biofuel.
1. chopped woodstick from energy forestry.
2. chipped wood from sawmillslabs.
3.wood pellets.
