Sewage Sludge Incinerator
Sewage Sludge Incinerator
Land filling and land application of sewage sludge is not a feasible solution and also is no longer allowed in many countries. The better the wastewater treatment process, the more toxic, or grubby is the sludge. Incineration of sewage sludge is the safest and the most recommended way of turning a problem waste into an opportunity. Sludge incineration remains the only viable method for sludge treatment. Bio-solids such as industrial, municipal sludge and fine solids can be incinerated with the power packed advantages of eliminating the sludge. The heat and energy produced during the incineration process can be harnessed and used as Green energy source.
Navrattan’s Sewage Sludge Incinerator burns wet sewage sludge to produce heat and electricity. The technology is such developed to solve the sewage sludge disposal problem, destruction of biogas residues and solid waste destruction problem in India.
Description
An Innovation in the renewable energy sector, Sewage Sludge Incineration is a technology that uses high moisture content sludge to burn it at source by employing the latest technology equipment for incinerating the sewage sludge mixed with RDF Granules, and biogas residue. The incinerator is a novel technology with the possibility of harnessing the generated heat and energy and using it for electricity generation.
During the incineration process, combustible material is oxidized and energy is released. Only a small amount of energy is lost by radiation over the surface of incinerator and the boiler as well as heat in the filtered ashes. In our sludge incinerator, 80% of the energy is recovered by a boiler, and the generated steam is used to produce electricity and heat for the drying of the sewage sludge.
During the combustion process, organic pollutants, endocrine disruptors and pathogens contained in sewage sludge are destroyed, and volatile heavy metals such as quicksilver are transferred to the flue gas. The nutrients, especially phosphorus, are not transferred in the form of gaseous compounds to the flue gas and are kept in the incinerator ash. In fluidized bed incinerators, most of the generated ashes have a very small particle size and are transported with the flue gas flow.
During the incineration process, sewage sludge is combusted and the energy is recovered as heat and electricity. These “products” are first of all used to cover the incineration plant’s own consumption; the residuary amounts of energy can be sold. The fluidized bed material containing some small amount of ash has no market value but can be used in road construction for example, or to produce other construction materials. The residues from the flue gas cleaning can be cost-intensively disposed of or can also be cost-intensively stabilized and further used in the construction industry, e.g. for cement production, in the manufacture of building ceramics, or as a substitute for sand or cement in road construction.
Advantages
Advantages of the incineration process:
- The sewage sludge and waste are incinerated in an environmentally sound manner, without the intervention of human hands.
- The heat generated is recovered and is used in generating electricity
- Eliminate the problems like sludge transport, pollution
- A Safe alternative of landfill
- Total elimination of sludge excess
- Energy recovery
- Destroys toxic chemicals
Characteristics of the Technology
