RENEWABLE ENERGY - BIOMASS
SAEL has proven its expertise in the design, construction and operation of biomass plants for the large-scale generation of electricity in India without increasing the carbon footprint. Our biomass plants (15 MW each) are located at Ghazipur, UP and Muktsar (Channu) Punjab.
Generation of electricity with biomass enables us to develop the rural economy, and also renew and replenish resources. With over 24 types of fuels identified, our biomass plants are known for their efficiency and scalability.
With over 10 years of experience in this field, we offer reliable and efficient solutions in the most advanced technologies. We also install biomass plants for other customers on BOT (build, operate, transfer) basis.
IMPACT OF PADDY-STRAW BURNING IN INDIA
With no organized market available for farmers to sell the paddy stalk, the options available are to either invest in expensive labour or burn the paddy straw in the field itself. A study conducted by the Adesh Institute of Medical Sciences and Research( AIMSR) and the Malwa branch of Association of Physicians of India had the following results:
The burning of agri-residue affects the health of nearly 85% people living in Bathinda and Muktsar.
76.8% of those surveyed reported irritation in eyes.
44.8% reported irritation in the nose.
45.5 % reported throat irritation.
18% people reported wheezing & 21% felt tightness in the chest.
Paddy-straw burning has been identified to be one of the biggest pollutants in India. Apart from smog and a sharp rise in Carbon dioxide levels, the straw burning also significantly reduces the organic matter, major nutrients and microbial biomass in the soil affecting the next crop season. One tonne of rice straw accounts for the loss of 5.5 kg of nitrogen, 2.3 kg of phosphorus, 25 kg of potassium and 1.2 kg of sulphur in the soil.
IMPACT OF SAEL'S BIOMASS PLANTS
By generating electricity from biomass, we ensure renewability, and the consistent flow of raw material is not subject to uncontrollable circumstances such as adverse weather conditions. Paddy straw, cane trash, cotton stalk, mustard stalk, and rice husk form the bulk of biomass residue used for power generation.
Rice husk is the most prolific agricultural residue in our rice-producing mills. It is one of the major by-products from our rice milling process. The benefits of using rice husk technology are numerous. Primarily, it provides electricity and serves as a way to dispose of agricultural waste.
Rice straw can either be used alone or mixed with other biomass materials in direct combustion. In this technology, combustion boilers are used in combination with steam turbines to produce electricity and heat.
1 ton of Rice paddy produces 290 kg Rice Straw
290 kg Rice Straw can produce 100 kWh of power
Calorific value = 2400 kcal/kg
