Design Specifications

The CleanCook Comet 1 & 2  Stoves are single and double-burner non-pressurized alcohol stoves  for households and institutions made from aluminum, galvanized steel  or stainless steel. The Comet 1 & 2 stoves come with  refillable fuel canisters of 1.2 liters capacity and 1.60 kg weight when full. The canister contains a porous fiber that absorbs alcohol and retains it in a manner that prevents spills, leaks, fires and explosions. After fuel refilling fuel canisters can be inserted from the stove side in an up-right position while the pot is still placed on the pot support, allowing the stove to be refueled quickly. The power output per burner is rated at 1.8 kW at maximum heat, allowing for a cooking time of 4.5 hours. It can burn ethanol and methanol with an efficiency greater than 60% and meets Tier 4 emission requirements. It consists of a built in windshield and a mechanical regulator – a lever moves a metal disk that uncovers an opening for evaporating fuel. The regulator can be used to adjust or extinguish the flame.

• The Comet 1 weighs 1.7 kg (excl. the canister) with Dimensions (W x D x H) - (295 x 290 x 170) mm.
• The Comet 2 weighs 4.0 kg (excl. the canister) with Dimensions (W x D x H) - (615 x 290 x 170) mm.

Product Schematics

Technical Support

Provided by local distributors and majorly the manufacturer

Replacement Components

Replaceable components include the fuel canisters and the stove body (a full assembly made up of different parts).

Lifecycle

Expected typical lifetime is six years for the aluminum body stove and 10+ years for the stainless steel stove

Manufacturer Specified Performance Parameters

Cooking efficiency greater than 60% , 1 L of fuel per day will provide cooking for a family of 5. A maximum power of 1.8 KW and negligible soot production meeting Clean cooking alliance tier 5 requirements and WHO standards for CO2 emissions with an innovative fuel canister that absorbs the fuel allows for the  fuel to evaporate and mix with air. The mixture burns above the canister opening with no wick and the chimney effect increases its power output.

Vetted Performance Status

Tier 4 for efficiency/fuel use Tier 4 for total emissions and indoor emissions

Safety
