Q:Liquefied petroleum gas, artificial gas, the calorific value of natural gas

Every kilograms of liquefied gas calorific value of 11000 kcal. Gaseous liquefied gas proportion is 2.5 kg / m3. Per cubic liquefied gas calorific value of 25200 kcal. This can be seen in a cubic liquefied gas burning natural gas calorific value is three times, but there are also reports that 7 times the calorific value of natural gas is liquefied gas.Each bottle of liquefied petroleum gas weighs 14.5 kg, a total calorific value of 159500 kcal, equivalent to the combustion heat value of 20 cubic meters of natural gas

Q:The gas in the gas tank is used up. What's wrong with the water?

Oh ~ upstairs to say another reason. I know there's an explanation, the gas tank is used in high density gas compression, the compression of a substance needed to prevent gas in high density compression due to the expansion of the explosion of molecular collision friction, when the gas is exhausted, the substance is left in the bottle, hot and cold temperature and other factors after sublimation into liquid.

Q:My gas tank in the winter time, each time, or stop shaking, or put him in a pot and add hot water. Don't know how to use safe? It is cold in winter, the gas tank gas can not be as good as usual should rise, how to use it?

5, ignition method. The correct ignition method is "fire and gas", that is, first unscrew the valve and the valve on the switch, and then open the switch on the stove ignition.6, the pressure reducing valve to check the sealing rubber ring, do not change, defect, install the valve hand wheel to the valve port, to counter clockwise rotation.Connecting parts 7, rubber tube, stove switches, pressure relief valve and the valve hand wheel to the bottle is easy to leak site, please check the leak brushing with soapy water to check the site, do not use fire leak.

Q:The status quo of the world and China's natural gas

2, the world's natural gas industry will enter the golden period of developmentIn the next century, the world's natural gas industry will enter a "golden age"". According to the International Energy Agency forecast in Paris, from now until 2020, global primary energy demand will increase by 65%, of which the needs of the developing countries than the current double - fan. In this perspective, the world's natural gas demand will increase by 2.6% per year, when the proportion of primary energy consumption will rise from the current 20% to 30%.The development of the natural gas industry has benefited from many advantages. International Federation of natural gas industry figures show that the world has proven natural gas reserves of 152 trillion cubic meters, according to the current level of consumption can be exploited for 65 years, only proven oil for exploitation for a period of up to 43 years. If viewed from a long-term perspective, the world's largest reserves of natural gas, that is, the current technical conditions can be mined, an estimated 400 trillion cubic meters.Another advantage of natural gas is the high utilization ratio of heat energy. In a few years ago, the thermal efficiency of gas-fired power plant is less than 40%, with the progress of related technologies, today has reached more than 60%. At the same time, some of the power supply and heating gas station, the utilization rate of natural gas and even 90%. Therefore, natural gas can be said to be a considerable economic energy.

Q:How to safely use the gas?

Five, what is the phenomenon of a red flame flame? What are the risks? How to deal with?The gas flame is normally pale blue, if found to be red, which means that the phenomenon of incomplete combustion. The risk of carbon monoxide poisoning will be immediately brought to the maintenance and adjustment of the stove.

Q:1 liquefied petroleum gas and gas?2 what kind of fuel is used in cooking and cooking?3 where can we find the price of all kinds of fuel?

There is also a commonly used gas fuel is natural gas, but also piped, because of its non-toxic and high calorific value, is now gradually replacing gas as the main body of urban gas fuel.

Q:How to do gas pipe leakage

Telephone alarm. Where there is no gas leak, call the police.Found that the pressure regulator, pressure regulator cabinets, underground gas pipelines, such as leakage of gas, gas appliances should be closed immediately, plug valves, ball valves, cut off the gas source, put out the fire. Where there is no gas leak, call the gas company.Power off. Remember to breathe that fire off. Should immediately close the plug valve, ball valve. If the plug valve, ball near the flame, the use of wet towels, wet clothes wrapped hand, try to close the valve. Try to extinguish the fire. Use of fire extinguishers, wet quilt beat the flame. Evacuation personnel. (4) telephone alarm.

Q:Before the fire is blue now the fire is yellow and the bottom of the pot to burn black is the gas is not pure or stove need to adjust?

This is not how to adjust the problem, gas stove flame is yellow in the liquefied gas adulteration.Method for distinguishing liquefied gas from adulteration"One of the most intuitive way: watch the flame color. In the normal combustion process, the normal liquefied petroleum gas flame was bright blue, combustion is very strong, and after the addition of two methyl ether, due to insufficient combustion, the flame was yellow, blue, very little.

Q:Water heater is good or natural gas

[compare]In 1, the ratio of hot water productionGas water heaters are 5 liters, 7 liters, or a liter of 10 liters, such as the size of the figure refers to the water temperature in the water temperature increased by 8 minutes when the temperature of 25 degrees in 1 minutes. Electric water heaters are generally marked 30 ~ 90 liters or more, this figure refers to the water capacity of electric water heaters. Take a 8 liters of gas water heater with a water heater of 60 liters, compared to a liter of gas water heater can be continuously produced every minute of 8 liters of hot water, water consumption is not limited to 8 liters. The electric water heater needs half an hour to heat a pot of water, if the water tank run out, but also about half an hour or so. In the winter, if the bath time is not good, can not run out of a tank of water, it would have to wait for half an hour to continue to wash

Q:How do I open the valve, or no gas ah?

According to the end, and then turn left, with the turn of the electronic ignition open, ignite the gas according to the need, the size of the fire with the switch to adjust, the greater the left turn, and vice versa.
