# Operating cost of 6 ton gas steam boiler

Time : 2021-09-22

Gas boilers are classified according to the type of fuel used by the boiler. Their fuels include natural gas, coal gas, liquefied petroleum gas and biogas. But the most used fuel is natural gas, so gas boilers usually refer to natural gas boiler products.

Before purchasing a boiler, users must not only consider the quality and price of the boiler, but also consider the thermal efficiency and operating cost of the boiler. Boiler is a kind of large-scale industrial equipment, and its later operating cost is not low. The boiler has high thermal efficiency, which can effectively reduce the operating cost of the boiler!

So today we will calculate the operating cost of a gas boiler.

Take a 6-ton gas-fired steam boiler as an example:

1, gas cost

The 6-ton gas-fired steam boiler has a rated steam output of 6 tons per hour, and the maximum gas consumption is 70 cubic meters.

2. Electricity cost

The main electrical part of the 6-ton gas-fired steam boiler is the burner and the water pump, and the others are weak electricity. The burner power is 8kw, the water pump power is 7.5kw, and the other weak electricity is 2kw.

3, water cost

The 6-ton steam boiler can turn 6 tons of water into 6 tons of steam in one hour.

4, labor cost

The gas-fired steam boiler is a fully automatic boiler, which only requires manual round-trip inspections. There are two shifts. One inspector works 12 hours a day at a salary of $300 per month.

5, maintenance cost

Fully automatic natural gas boiler, the failure rate is very low, and the maintenance cost is also very low. The maintenance cost of a 6-ton gas-fired steam boiler is $1000 a year. A year is based on 365 days, 24 hours a day.

6. Boiler cost and installation cost

The 6 ton gas-fired steam boiler manufacturer quoted $45,850 (including tax and freight), and the local installation and commissioning inspection fee was 95,000 yuan.

7. Boiler house infrastructure investment

In the drawing plan, the planned use of land is 26m*17m=442m2. The manufacturer estimates based on the use area of 3 boilers: L=16m, W=15m, H=7m, and the planned building area is 16m*15m=240m2.

8, pipeline construction cost

The estimated straight-line distance from the steam pipe in the planned natural gas boiler area to the steam distribution valve in the production workshop is not less than 105 meters. Calculated based on the specifications of steam pipes currently used by industrialized companies, the reference cost for the production and installation of steam pipes to keep warm is 1,000 yuan/extended (overhead form, the overhead height of some road areas is not less than 4.7m, and the reference diameter of the steam pipe from the boiler room branch valve is DN65. , The thickness of the seamless steel pipe is not less than 3.5mm.) The service life is 10 years. According to the calculation method that the depreciation life of fixed assets under high corrosion conditions is not less than 60%, the set life is 6 years.

Therefore, if there is a boiler demand, it is recommended to carefully choose the boiler manufacturer. There are many boiler manufacturers, but not many manufacturers with good qualifications, and only a few can have A-level boiler qualifications. For example, Fangkuai boiler has A-level boiler manufacturing qualification and first-level boiler installation qualification. Focus on condensing boilers for more than 20 years, and be the leading condensing boiler in China. In addition, the boilers of large factories are guaranteed and the prices are low. The control of various parameters is relatively good, and no additional costs will be incurred. For example, the quotation of ordinary natural gas boilers is directly issued by the manufacturer with high quality and low price. The thermal efficiency is high, and the heating area is larger than that of general boiler manufacturers. Some common boiler problems can be avoided, the cost of gas-fired boilers can be reduced, and the cost-effectiveness of corresponding boilers can be improved.
