TURBO STOVES A durable innovation for use in developing regions

A New Cooker that Operates on Bioenergy

Hundreds of various types of stoves made of stone, clay and sheet metal have not been able to solve the problems related to the preparation of food by women under conditions in the developing nations. Regardless of the catastrophe-related causes, people require food and firewood. Amongst all the food shipments, tents, pots and cauldrons, there has been a distinct lack of cookers incorporating bioenergetic and other agricultural waste materials in their heating systems.

A new cookstove capable of acceptance by large groups of people in various cultures must fulfill a considerable number of different requirements. The Turbo Stove has been planned to meet the following user demands, among others:

A Turbo Stove is beneficial to family health, safety and convenience

Turbo Stoves are easy to operate. Not only does a Turbo Stove provide fire-related control possibilities but it also works well under both general outdoor and windy conditions - offering a low level of emissions, high durability, safety in regard to fire hazards, protection against burns and scalds and rapid attainment of boiling temperature.

A Turbo Stove raises the social status of the house hold. It is stable, portable and light in weight. It generates warmth and provides light. Practically any size of pot or pan is appropriate for a Turbo Stove and cleaning is easily accommodated. In addition, its shape and contours are pleasant in appearance.

The Turbo Stove represents a technical link between household energy-related problems and various agroforestry models

The concept of sustainability is foremost, Because of its basic technical design, duplicating the Turbo Stove on the local level is feasible.

This cooker belongs to the group of metallic, one-pot, chimney-free, portable and bioenergetic cookstoves.

It is efficiently fabricated from the stage of plain metal sheet to semi-finished assembly kit. The kit itself is a comprehensive unit consisting of seven parts which are separated by hand for final assembly.

When assembled, the Turbo Stove generates excellent combustion based on a special combination of primary and secondary air flow through the combustion chamber. The primary air flow can be regulated by the two-level adjustable grate as the preheated secondary air enters the combustion chamber through holes in the inside wall. The process is based on thermal expansion acting between the two walls.

Preheated secondary air is pressed into the combustion chamber by thermal air expansion between the two walls, which are heated by fire in the combustion chamber



The stove can be assembled by hand in 20 minutes or less. This feature makes it unmatched throughout the world.

A Turbo Stove releases minimal emissions of smoke in respect to toxic carbon dioxide (CO) and other respiratory particles which otherwise pose a threat to the heath of women and children. With respect to women, Improvements in this field in health, safety and convenience enjoy top priority.

Tapio Nierni, Master of Forestry the inventor of Turbo Stove:

"With the ever-increasing shrinkage of our planet's fuel supplies together with its continuously growing air pollution, efficient usage of fuel having low- emission levels is crucial for the world's entire populace and environment. Aside from the conservation standpoint, fuel efficiency is also important from an economic perspective, since there are large segments of the world's population which live in poverty.

The development of Turbo Stoves took ten years. Tapio Niemi acted as Information Department Project Supervisor in Kenya and The Sudan for Enso Forest Development Ltd. It was his responsibility to develop the forest related counseling and information organization. In practice, this work concerned the development and educational training respective to agroforestry models as well as nursery gardens, water collection systems and counseling methods. Turbo Stoves originated in response to local population needs: a well-functioning woodburning oven had not been available

Technical Information

Turbo Stoves are extremely strong as relevant to mechanical impact, and are also capable of withstanding fire as well as corrosion for a period of many years when fabricated from heat and acid-resistant stainless steel or strong cold rolled steel. Polarit 725 incorporates austenitic stainless steel, which corresponds to EN 1.4301 (Standard Specification EN 10088-2) and AISI 304 (Standard Specification ASTMA 167). Technical Service Outokumpu Polarit Oy Ltd


EN 1.4301 is the most commonly used stainless steel of those which are resistant to corrosion as utilized in, e.g., the chemical, paper and food industries. This grade of steel is also popular in household appliances, architecture and transportation. The excessive scaling temperature is close to 850' C.

Corrosion resistance

Climactic resistance with respect to corrosion is adequate in most cases without any surface handling (e.g., painting)


Certificate of Approval awarded to TEHO FILTER OY LTD


Quality standards: BS EN ISO 9002:1994

TEST RESULTS FROM THE TECHNICAL RESEARCH CENTRE OF FINLAND/ COMBUSTION AND CONVERSION TECHNOLOGY VITA INTERNATIONAL WOODSTOVE TESTING STANDARDS Low CO concentration protects the stove user, and the low level of CO' is beneficial in protecting the environment A Turbo Stove boils 4 liters of water in 22 minutes with 25% energy efficiency without a pan-lid and with 30% energy efficiency when a pan-lid is used.
