What is insertion loss in DG set?
2.3 The DG set shall be provided with proper exhaust muffler with insertion loss of minimum 25 dB(A).
What is SFC of DG?
Specific Fuel Consumption (SFC) expressed in litre/hour or gm/kWh is an indication of the quantity of diesel required to generate one unit of electricity. This parameter is of direct relevance to end users as it relates to the operating costs of generating electricity from diesel generator sets.
What is CPCB engine?
So, the Central Pollution Control Board (CPCB) in collaboration with the Ministry of Environment and Forests has laid down emission regulations for diesel gensets. Emissions standards for new gensets with up to 800 kW generator engine. Gensets with power up to 19 kW.
What CPCB 2?
The new CPCB II norms will be applicable from April 1, 2014. The amended rules mandate all manufacturers, importers or assemblers of diesel generator sets in India to comply with the cleaner emission standards, for products up to 800 kilowatt.
What is Apcm in pollution?
Air Pollution Control Machines (APCM)
What is the maximum height of the stack for industry?
The height of the stack shall be atleast 30 metres. December 1987. In this group of fertilizers, there are fifty one companies manutacturing single super phosphate (SSP).
What is the minimum height of the stack for industry?
Particulate matter 50 mg/NM3 Lead 20 mg/NM3 (ii) Minimum Stack height should be 30 metres in lead glass units. Note : Depending upon local environmental conditions, State/Central Pollution Control Board can prescribe more stringent standards than those prescribed above.
What is the safe noise level to work?
OSHA sets legal limits on noise exposure in the workplace. These limits are based on a worker’s time weighted average over an 8 hour day. With noise, OSHA’s permissible exposure limit (PEL) is 90 dBA for all workers for an 8 hour day.
What is ISFC and BSFC?
What is BSFC and ISFC? The BSFC (Brake specific fuel consumption) is the ratio of fuel mass flow rate (ṁf) to the brake power (BP) and ISFC (Indicated specific fuel consumption) is the ratio of fuel mass flow rate to the indicated power of an engine.
How can you increase the efficiency of a DG set?
small sizes of gensets are now converting their air cooled HX to water cooled type so as to avoid engine overheat in summer months and to maximize the efficiency, reduce the cooling losses and improve the loading levels. It is recommended to use clean water as cooling water in radiator.
What are CPCB norms?
Table 1
| Designated-Best-Use | Class of water | Criteria |
|---|---|---|
| Irrigation, Industrial Cooling, Controlled Waste disposal | E | pH betwwn 6.0 to 8.5 Electrical Conductivity at 25C micro mhos/cm Max.2250 Sodium absorption Ratio Max. 26 Boron Max. 2mg/l |
| Below-E | Not Meeting A, B, C, D & E Criteria |
What is meant by effective stack height and what factors control this?
The effective stack height is the sum of the actual physical height of the top of the stack, plus any plume rise due to buoyancy or initial momentum (inertia) of the rising effluent, minus any downwash such as stack downwash, building downwash, or terrain downwash.
What is OSHA noise limit?
OSHA – Occupational noise exposure 1910.95. OSHA sets legal limits on noise exposure in the workplace. These limits are based on a worker’s time weighted average over an 8 hour day. With noise, OSHA’s permissible exposure limit (PEL) is 90 dBA for all workers for an 8 hour day.
What is maximum attenuation?
The magnitude of the maximum attenuation change of each individual fiber shall not be greater than 0.15 dB/km at 1550 nm The change in attenuation measurements shall be in accordance with EIA/TIA Standard FOTP-3.
What is the stack/chimney height calculator?
The calculator (stack/chimney height) is based on the various published, notifications and guidelines by Ministry of Environment, Forest and Climate Change, Government of India and Central Pollution Control Board, New Delhi. Application: To determine the regulatory, minimum stack heights in various industries.
How do you calculate the minimum height of a generator stack?
The minimum height of stack to be provided with each generator set can be worked out using the following formula : H = h+0.2 x √ KVA
What are the harmful effects of a set of DG sets?
DG sets emit some amounts of oxides of Nitrogen, Carbon Monoxide, Sulphur Dioxide, and other particulate matter, which can harm the surrounding habitat and organisms.
