(1) How does the natural gas ladder charge work?

Cities are different, one more step is expensive, and two more steps are expensive.

(2) what do you mean by the first and second order of natural gas?

Ladder gas price refers to the segmented pricing of gas consumption by users after residents exceed the basic consumption of natural gas every year or month.

The ladder gas price should be divided into three grades:

The first gas consumption is less than 35 cubic meters per month, that is, less than 420 cubic meters per year.

The second gas consumption is more than 35 cubic meters per month-less than 55 cubic meters, that is, more than 420 cubic meters per year-less than 660 cubic meters.

The third gas consumption is more than 55 cubic meters per month, which is more than 660 cubic meters per year.

(2) What are the conditions for the first-order expanded reading of natural gas?

The implementation of the residential gas ladder price system follows the following basic principles:

1. First, combine the basic guarantee with reflecting the scarcity of resources. The price is relatively low for residents' basic domestic gas demand; For the part that exceeds the basic domestic gas demand, the price should be appropriately raised to reflect the scarcity of natural gas resources.

2. The second is the combination of compensation cost and fair burden. On the whole, residential gas prices should gradually reflect gas costs and reduce cross-subsidies. At the same time, the burden of gas consumption is fair, and residents who use more gas have more burdens.

3. The third is the combination of unified policies and local conditions. The overall framework and guiding opinions of the state for formulating the residential gas ladder price policy, and the specific implementation plan is determined in combination with the local natural geographical environment, economic development and residential gas characteristics.

③ Natural gas ventilation conditions

2. Do not use gas to add plugs and seals.

3. Due to the serious transformation, the pipeline cannot be repaired, so it should be sealed.

4. According to the drawing requirements, the gas stove should be equipped with flameout protection device.

5. Anyone who changes the kitchen into an open kitchen will be sealed without ventilation and ignition.

6. The gas pipeline passes through the living room, the flue, the hose passes through the wall, and the buried pipe is sealed.

7. Houses where people live in kitchens or are converted into study rooms should be blocked and sealed.

8. Non-civilian users add plugs and seals.

9. Unauthorized removal, alteration, migration, plugging and sealing.

10. Users with the above conditions will not be suppressed if they do not implement blocking.

④ What are the conditions for using natural gas from natural gas companies?

Natural gas companies generally review the "factory inspection certificate" and "warranty card" of gas cookers, and some companies also need the local "return air quality adaptation test answer sheet" (which should be within the inspection period). The installation unit must have qualified installation qualification, and send personnel with installation qualification certificate for installation. After installation, it is necessary to issue an "installation acceptance certificate" to the user, and it is recommended to consult the local natural gas company in detail. The requirements for natural gas companies vary from place to place. Who will be responsible for the timely maintenance of natural gas cookers and water heaters bought online?

⑤ What are the first-order conditions?

The meaning of derivative in connection mathematics.

The first-order condition is to find the first derivative, and the second-order condition is to find the second derivative.

In the economic forum of the National People's Congress, it is said that in order to satisfy the maximum value of a function, the derivative of its independent variable must be taken to make it zero, which is a first-order condition.

⑥ What conditions are needed for natural gas generation?

Large natural gas fields need to be developed under high temperature and sealed conditions for hundreds of thousands or even millions of years. Biogas made in rural areas can also be regarded as natural gas, because the composition is similar, and it takes about one or two months.

⑦ Natural gas installation conditions

The maximum pressure of indoor gas pipeline and the rated pressure of gas burner of gas equipment shall comply with the current national standard "Code for Design of Town Gas" GB 50028.

The maximum pressure of indoor gas pipeline and the rated pressure of gas burner of gas equipment shall comply with the current national standard "Code for Design of Town Gas" GB 50028.

In the process of gas pipeline laying, other pipelines may be encountered, and the clear distance between pipelines is strictly required. Only in this way can we achieve the specification of safe gas pipeline installation, such as horizontal parallel laying, and the clear distance shall not be less than150 mm; When laying in parallel and vertically, the clear distance should not be less than 100mm, and it should be located outside other pipelines; When laying crosswise, the clear distance shall not exceed 50 mm When using gas daily, the main purpose is to prevent the gas pipeline from leaking. This needs to be avoided from three aspects. On the one hand, when installing a gas pipeline, the pipeline should not be buried or sealed in secret, which is to prevent the pipeline from leaking without being discovered, thus creating danger. The interior decoration design is reasonable, and it is best to set the gas pipeline indoors. If it must be set outdoors, it must be rain-proof and sun-proof to avoid corrosion.

On the other hand, gas pipelines, gas meters, valves and other gas facilities must be produced by regular manufacturers, and their air tightness and corrosion resistance must be guaranteed.

Finally, it is necessary to check more, one is to check whether there is any leakage in the pipeline, and the other is to check whether the air valve is tight.

The installation of gas pipeline is related to the safety of kitchen gas, and the use of gas appliance also needs attention. No matter what kind of kitchen utensils, gas appliance should be set in a kitchen with good ventilation and exhaust conditions, and try not to set it in a rest place such as a bedroom. The clear height of the room where the gas stove is installed should not be less than 2.2m, and the clear height of the room where the gas water heater is installed should not be less than 2.4m.. ..

Thirdly, be sure to keep the room well ventilated to avoid accidents.

：

Compared with artificial gas, natural gas has the same calorific value and price year-on-year. Natural gas is clean, which can prolong the service life of stoves and help users reduce maintenance costs. Natural gas is a kind of clean fuel gas, and its stable supply can improve air quality, thus providing new impetus for economic development in this region, promoting economic prosperity and improving the environment.

With the use of safe and reliable natural gas at home and the friendly, professional and efficient after-sales service and new stoves provided by Hua Gang Gas, the family environment will be greatly improved and the quality of life will be improved.

Gas pipeline installation requirements

What is the first-order condition?

The first-order condition is to find the first derivative, and the second-order condition is to find the second derivative.

At the Economic Forum of the National People's Congress, it is said that to satisfy the maximum value of a function, the first derivative of its independent variable must be taken to make it zero, which is a first-order condition.

Pet-name ruby natural gas is divided into phase I and phase II, how to distinguish them?

According to meet different gas demand, residential gas consumption is divided into three grades:

The gas consumption of the first gear is 35 cubic meters per month or less, that is, the annual gas consumption is 420 cubic meters or less;

The second gas consumption is from 35 cubic meters to 55 cubic meters per month, that is, from 420 cubic meters to 660 cubic meters per year;

The third gas consumption is more than 55 cubic meters per month, which is more than 660 cubic meters per year.

The gas price of each gear shall be increased, among which:

The first gas price is the current gas price of local residents;

The second gas price is 1. 1 times the current price of domestic gas for local residents;

The third gas price is 65438+ 0.3 times of the local current gas price.

(9) What are the conditions for the first-order expansion of natural gas readings?

For non-resident users such as schools and pension welfare institutions, the ladder gas price will not be implemented for the time being, and the gas price level will be implemented according to the average gas price of the first and second stalls of local residents' domestic gas, that is, 65438+ 0.05 times of the current domestic gas price.

In terms of protecting the interests of low-income groups, according to the requirements, all localities should fully consider the economic affordability of low-income groups, and ensure that the basic living standards of low-income groups are not reduced while implementing the ladder price of residential gas. Where there are no preferential price measures for low-income groups, we should promptly formulate and implement preferential price measures; Where preferential price measures have been formulated and implemented, preferential prices may be appropriately raised if conditions permit.
