2021-04-16 09:41    page view:

Guide: Boilers are one of the large-scale equipment that many industries cannot do without production. At present, industrial boilers are in the most demand. However, with the increasing global environmental pollution, the country has also set the pollution emissions of various industries. Standards, efficient use of energy and energy saving and emission reduction have become very important, so how much natural gas does a gas boiler with a capacity of 4 tons burn every day? How to calculate the daily operating cost of a 4 ton gas boiler?

Boilers are one of the large-scale equipment that many industries cannot do without production. At present, industrial boilers are in the most demand. However, with the increasing global environmental pollution, the country also sets pollution emissions from all walks of life. Standards, efficient use of energy and energy saving and emission reduction have become very important. So how much natural gas does a gas boiler with a capacity of 4 tons burn every day? How to calculate the daily operating cost of a 4 ton gas boiler? Calculation of Gas Consumption of Gas Boiler

  Calculation formula: gas consumption of gas boiler (per hour) = gas boiler power * time / fuel calorific value / thermal efficiency.

  According to the uninterrupted operation 24 hours a day, multiplying the result of the above calculation formula by 24 hours is the total gas consumption of 4 tons of gas boilers per day.

  Take the specific rated power of 2.8MW and the calorific value of fuel 35.53MJ/Nm3 as an example for detailed calculation:

  Assume that the thermal efficiency of the gas boiler is 88%. Then, the hourly gas consumption of a 4 ton gas boiler = 2.8MW*3600s/35.53MJ/Nm3/88%=320m3/h.

  operates 24 hours a day, consumes natural gas=320*24=7680 cubic meters

Daily operating cost of 4 ton boiler

  There are differences in natural gas prices in various parts of the country, and the general price range is between 1.8-5 yuan. If it is used in industry, the selling price of natural gas is generally 1.8-3 yuan/cubic. Calculate the daily consumption of the above-mentioned 4-ton gas boiler. Gas volume 7680 cubic meters* (1.8-3 yuan) = 13824-23040 yuan.

How gas boilers are more energy-efficient

  1. Heat preservation. Most of the energy saving of gas boilers starts from the various parts of the boiler. For example, from the heat preservation of the boiler, it is necessary to ensure that the surface temperature of the boiler cannot be too high, generally below 50 degrees Celsius.

  2. Energy saver, gas boilers want to save energy and cost to maximize the efficiency of the boiler, install a boiler economizer, reduce the boiler exhaust temperature, and make good use of the waste heat.

  3. Thermostats, gas-fired hot water boilers can be equipped with thermostats, increasing the return water temperature can also play a good energy saving effect.

The above is the daily operating cost calculation method of the 4 ton gas boiler and the energy saving method of the boiler compiled by Xinli Boiler for your reference.
