Idea 1: Energy Efficient Metal Chulha for Solid Biomass by using Solar Operated Fan

Need of the Project

•In India, the burning of biomass in Chulhas for cooking food has been done for generations. • Even today, more than 60% of the rural population of India depends on biomass fuel for cooking. • The Chulha is a very inefficient device and only 10-20% of heat is consumed for cooking. • The burning of biomass in open stoves results in the release of smoke and high concentration of particulate matter. • These air pollutants are harmful for women and small children who are very often present in the kitchen for longer hours. • Due to the wastage of energy, the time required for cooking is also high.

• Very often, the biomass is collected from nearby forests and requires long hours of labour. • If the biomass is purchased then it is a big burden for the household budget. Thus, a policy was initiated to improve the efficiency of cook stoves. • The improved cooking stove consumes less fuel and requires less time for cooking. • These stoves also emit less smoke and compared to traditional stoves improve indoor air quality by releasing harmful gases via the chimney..

Abstract

The Traditional Mud Chulha emitted considerable amount of toxic component, which can adversely affect the human health on direct exposure. To overcome this problem, I am going to developed an Energy Efficient metal chulha for solid biomass by using Solar operated fan, which significantly reduces energy loss and cooking time. It is expected that, the energy efficient metal chulha reduced specific fuelwood consumption, increased efficiencies and lower emissions of pollutants including PM10, PM2.5, NOX, SOX and CO.

Introduction

Cooking and heating with dried biomass release toxic pollutants in the indoor environment. The inefficient way to burn solid biomass fuel releases a large amount of air pollutants, including fine particles (PM10 and PM2.5) and gaseous pollutants (CO, SOXand NOX) that present a high environmental risk.
Therefore, the objectives of my project is to develop an improved metal chulha over commonly available traditional mud chulha for rural households; This contribution helps to raise awareness about the need for improvement in design and provides evidence data for policy implication and to switch on improved and better designed cookstoves and better designed for health care of the rural people, their economic concerns and climate benefits.

Expected Output of the Project

With Installation of Energy Efficient metal chulha it will enhances the thermal efficiency with the reduction in specific amount of fuelwood consumption. It will further reduced the duration of time and the amount of fuel to prepare a particular amount of food. It will also reduced the concentration of indoor air emission, which reflects the lower concentration of pollutants into the indoor kitchen environment and help to reduce fuelwood consumption and less exposure to smoke, especially women responsible for daily cooking in the indoor kitchen.


Idea 2: Solar Powered Smart Kitchen Chimney


Scope of the Project

•In India, the biomass is used for generation of heat for cooking process.
• In rural area, the biomass is available in huge quantity.
• The burning of biomass, can release smoke and high concentration of particulate matter.
• Which dangerous for health of person working in kitchen and person who will come contact with the smoke.
• So, it is necessity to absorb this smoke from kitchen, before it gets add into the atmosphere.


Abstarct

A smart kitchen chimney uses the solar energy as a power source the run the DC fan of the chimney. When the smokes come in contact with the sensor of chimney, the signal will gets to Arduino microcontroller, the exhaust fan will get operate, which can absorb the smoke from kitchen and send it into carbon charcoal filter where the carbon and other hazardous gases will get absorbs and the smoke will exhausted into the atmosphere.


Introduction

The chimney is the passage through which smoke and combustion gas escape from workplace to outer environment. The existing chimneys are operated based on AC source which is more costlier and some places the electricity is not available. In order to overcome this difficulty our entire system works on DC source. From solar panels we get sufficient DC supply to operate the entire system. Solar energy is a renewable energy which we can generate at low cost.
The normal exhaust fans in household as well as in all other workplaces have a manual speed control system. it is regulated using a rotary switch which internally involves a potentiometer, the potentiometer adjusts current flow to the exhaust fan and hence, the speed is adjusted this system creates a few problems in terms of user comfort. To avoid this automatic on/off control technique is implemented in our proposed system.
The automatic on/off control process of exhaust fan is made by Arduino microcontroller and smoke sensor. The smoke sensor detect the smoke more accurately and send required data to exhaust fan module and the fan get operate.
