![]() Notifications such as text messages, emails, or push notification can be sent out to users for refueling and maintenance. The feedback from the sensors in turn, manages the opening and closing of a damper and a variable speed blower.ĭata collected by the automated control technology can be viewed wirelessly through a display and cellular application. The automated controls incorporate the following sensors: a thermocouple to monitor the firebox, catalyst, and vent operations, and a Bosch oxygen sensor in the vent to ensure proper fuel-air mixture. ![]() This ensures that the catalyst is working at its full potential to reduce the amount of carbon monoxide and particulate in the exhaust before exiting through the vent. The Catalus Ventus utilizes an active catalyst, which is preheated prior to starting and reloading of the wood stove. The retrofit incorporates ClearStak’s preheated catalyst technology, a dual cyclone, and is managed by ClearStak’s automated control technology. Website: Email: Catalus Ventus is a catalyst-cyclone prototype designed to attach to the back of any existing stove on the market. Team: Jeff Hallowell, Corey Vann & Jessica Peterson The cost of the stove is estimated at below $500 wholesale. The stove was tested using gravimetric measurement of PM 2.5 and the average of three tests was 0.25g/hr. The combustion chamber was tuned under the ARC emission hoods by Li Hiaxi as part of a DOE grant. The heat exchanger is dependent on a large fan and surface area was added until exit temperatures approached ambient. A unique Chinese invention, a hemispherical cap above the secondary air holes increases the combustion efficiency.Īprovecho has added a heat exchanger with access port to the stove. Jets of preheated secondary air induce swirl and create a zone of superior mixing above the fuel. Primary air enters the cylindrical FeCrAl combustion chamber at the bottom regulating the rate of burn. ![]() Chinese stove researchers have been experimenting with batch fed top lit stoves for about two decades and several very large manufacturers sell clean burning TLUD cooking stoves. Both natural draft and forced draft top lit up draft (TLUD) cooking stoves have scored well in recent EPA cook stove tests. The combustion chamber is a refractory metal cylinder made from FeCrAl 18" in diameter and 28" deep. It is a new concept taking advantage of the very clean technology now used.

There are limited spaces for participants and we are looking for high levels of experience in a stove related field. Chinese Three Stage Stove, by Aprovecho Labĭuring theWorkshop, the teams and workshop participants will witness the testing, review test results each morning and discuss how to improve each stove.* These 2 stoves were admitted, but did not compete Four are international entries and 3 are domestic. Seven stoves were selected to take part in the Collaborative Stove Design Workshop at Brookhaven National Lab in November 2014. ![]() Stoves Competing in the Stove Design Workshop
