Frequently Asked Questions - HCG

CNG - FAQ’s

Answer: CNG stands for Compressed Natural Gas. It is a gaseous fuel and is a mixture of hydrocarbons, mainly methane, in the range of 89% to 90%. It is compressed to a pressure of 200-250 kg/cm² (g) to enhance the vehicle on-board storage capacity.
Answer: CNG is safe. It is lighter than air, so in case of a leak it just rises up and disperses into the atmosphere. Besides, a high auto-ignition temperature of 540 degrees centigrade as against petrol's 360 degrees centigrade makes it a safe fuel. , if CNG’s concentration in the air is less than 5% or more than 15%, the gas will not burn even in the presence of a spark.
Answer: All petrol and diesel engines can be converted to CNG, but a specially designed conversion kit is required for the purpose. The kit consists of a cylinder to be fixed in the car boot and other equipment to allow gas flow into the engine.
Answer: Of course even after conversion to CNG, the vehicle continues to be fitted with the petrol carburetor and fuel tank. Hence the vehicle can run on dual fuel - CNG or petrol, by simply flicking a switch which is fixed, to enable this facility on the dashboard.
Answer: CNG vehicle starts easily, it has reliable idling and smooth acceleration. The acceleration of a CNG vehicle is a bit slower due to a power loss of 5-15%. This can be minimized by proper tuning on CNG by advancing the spark timing in order to take advantage of the high octane rating of the fuel.
Answer: Of course a diesel vehicle can be converted to CNG, but the conversion cost would be higher than of conversion of petrol vehicles.
Answer: CNG emits less carbon dioxide and other pollutants as compared to liquid fuels. Thus, CNG contributes less air pollution. It also helps to improve the balance of payments by acting as a substitute for imported liquid fuels and provides more business as well as job opportunities being a new work sector. It appeases the motor masses for being competitively priced.

PNG-FAQ’s

Answer: Natural Gas is primarily methane-CH4 with a small percentage of other higher hydrocarbons. The ratio of carbon to hydrogen is least in methane and hence burns completely making it cleaner fuel. PNG is produced from the oil & gas wells, after it is purified the natural gas is transported through pipelines network across the country and further to the consumer. Natural gas is most versatile fuel which can replace most of existing form of fuels like petrol and diesel.
Answer: Natural Gas is not stored at one place, it is continuously supplied through pipelines. It is much safer than LPG which is stored in cylinders.
Answer: Yes definitely PNG is better as it is continuous supply through gas pipe line where as LPG is filled in a cylinder which has a fixed capacity and then installed.
Answer: Yes, the supply is continuous. The pipeline distribution network is based on an on-line supply system that consists of safety valves and regulators that control and monitor the gas supply and pressure and assist in identifying system leaks. Thus an un-interrupted supply at a constant pressure is assured.
Answer: No, it does not require any change in the appliance, with some minor modifications LPG appliance can be easily converted to PNG. The working of PNG is the same as LPG.
Answer: The cost of PNG connection is dependent on the type of house or establishment based on that the installation charges are applicable. At the time of registration for a PNG connection, a refundable security deposit (interest free) has to be deposited.
Answer: : Billing is based on the meter readings taken by the authorized staff once in two months for domestic consumers and daily for commercial customers.
The bills are delivered at the customer's residence or establishments. The payment of the bills can be made online and offline as acceptable by HCGDPL.
Answer: We have 24x7 helpline service for attending to queries & complaints. Our network control rooms are working 24 hours and by engineers and technicians attend to the issues. They can be reached on our Emergency No: 9311990900
Answer: The combustible mixture of natural gas and air does not ignite if the mixture is leaner than 5% and more than 15% of the fuel/air ratio, required for ignition. This narrow inflammability range makes PNG one of the safest fuels in the world. Natural gas is lighter than air. In case of a leak, it rises up and disperses into air given adequate ventilation is available. But LPG being heavier settles at the bottom near the floor surface.
PNG is safer as it is installed inside the premises, it contains of limited quantity of natural gas at low pressure (leakage in LPG expands 250 times), which is not the case with PNG. The PNG supply can be switched off from the appliance valve in the kitchen and the isolation valve outside kitchen area cuts off the gas supply.
