The exhaust system of a DG (diesel generator) set is a critical component that expels the engine's exhaust gases. It typically consists of an exhaust manifold, muffler, and exhaust pipe, which work together to reduce noise levels and direct harmful fumes away from the generator. Regular inspection and maintenance of the exhaust system are essential to ensure efficient operation and compliance with safety regulations.
The retrofit emission control system for a diesel generator (DG) set is designed to treat the exhaust gases coming out of your existing generator’s exhaust line without modifying the engine itself. It’s installed directly in the exhaust path so that ALL exhaust gases pass through the retrofit device before leaving to the atmosphere. Here’s the step-by-step working principle: Installation on the Exhaust Outlet The retrofit device is fitted onto the DG set’s exhaust outlet — either before or after the existing silencer — but it becomes the primary path through which all exhaust gases flow. No mechanical changes to the engine or exhaust piping are required. Exhaust Enters the Retrofit Control Unit As the DG set runs, the hot exhaust containing harmful pollutants like particulate matter (PM), carbon monoxide (CO), hydrocarbons (HC), nitrogen oxides (NOx), and other contaminants flows into the retrofit emission control equipment. Filtration and Reduction of Pollutants Inside the retrofit system are filter and catalyst components (such as ceramic filters and catalytic media). These capture and break down harmful substances: Ceramic filters trap and filter particulate matter (including PM2.5 and PM10). Catalytic elements help oxidize CO and HC into less harmful gases. Some advanced systems also assist reduction of NOx. Regeneration & Self-Cleaning As particles accumulate in the filter, the retrofit unit periodically regenerates itself — burning off trapped soot or cleaning the filter surface — to maintain performance without significant manual intervention. Vasthi’s design can regenerate in about 10 minutes. Clean Exhaust Is Released After treatment, the much-cleaner exhaust gas exits the retrofit unit with significantly lower levels of particulate matter and pollutants, helping the DG set meet emission standards and reduce environmental impact.
To calculate the DG set current, you need the load current and the load voltage. To convert it into kilowatts it is divided by 1000.
The duration of a C check for a DG set can vary depending on its size and complexity. On average, a C check for a DG set could take anywhere from a few days to a couple of weeks to complete. It is best to consult with a qualified service provider for a more accurate estimate based on the specific requirements of your DG set.
What is the minimum height required for chimney of 100 KVA DG Set which is kept in
Rating for DG set and any of electrical machines is calculated in KVA. KVA is calculated as KW/pf. One can calculate the required KVA for DG set with this formulation: (KW/pf)/load rate. For example KW=110, pf=0.8 and one loads the DG at 75%, so KVA= (110/0.8)/0.75=185 KVA.

That would be a negative.The 490 which is probably a 1982 model as 1981 was a 465 were all side exhaust ports .The 82 yz 250 was a centre port with a twin tube frame. Also the expansion chamber on a 250 needs to be much larger than on a 490.You can get a new pipe from DG in usa or watch ebay. Good luck.
DG set is designed for 0.8 lag power factor. if it fall below this, we can used proper rating capacitor to improve this. what happens if we run the DG at .6 pf
To calculate the power factor (pf) of a 1010 kVA diesel generator (DG) set, you can use the formula: [ \text{Power Factor (pf)} = \frac{\text{Real Power (kW)}}{\text{Apparent Power (kVA)}} ] First, determine the real power (kW) output of the DG set, which can be obtained from the manufacturer's specifications or by measuring the actual load. Then, divide the real power by the apparent power (1010 kVA) to find the power factor. Typically, a power factor of 0.8 to 0.9 is common for DG sets.
