Gas-fired boilers use gaseous fuels as the main energy source to meet the needs of industrial manufacturing, production and life by outputting high-temperature steam or hot water.
Air consumption is an important indicator for assessing the overall quality of gas boilers. It is also one of the standards that users measure when purchasing boilers. This data will directly determine the input cost of the boiler operation. Only when the cost is controlled below a certain limit can the data be obtained. More benefits.
How to calculate the gas consumption of a gas boiler?
Gas consumption = Gas boiler power /Fuel calorific value / Gas boiler heat value utilization.
For example, we operate 1 ton gas boiler for 1 hour (full load). The boiler output is 600,000 kcal (fixed value), the natural gas calorific value is 36.22 MJ/Nm3 (fixed value), and the thermal efficiency is 92% (non-fixed value). According to the actual situation of the boiler, the calculation is carried out.
Then, the gas volume required for the operating hours of a 1 ton natural gas boiler = 0.7 MW * 3600 s / 36.22 MJ / Nm3 / 92% = 75 m3 / h.
Note: The actual power of the boiler is generally not equal to the rated power, so the consumption of gas is only a rough estimate. The specific data depends on the load of the boiler during actual operation.
What are the factors that affect the gas consumption of gas boilers?
After obtaining the gas consumption data of the gas boiler, we also need to know what factors affect the gas consumption of the gas boiler.
1. Boiler heating area
Generally speaking, the larger the heating area is occupied in the whole boiler, the more heat is transferred to the boiler by the fuel combustion, and the fuel utilization rate is improved.
2. Fuel calorific value and price
The calorific value of different types of fuels will also vary. The calorific value of natural gas combustion is 36.22 MJ/Nm3, and the calorific value of liquefied petroleum gas is 46 MJ/Nm3; however, fuel costs should also be considered.
3. Boiler thermal efficiency
The thermal efficiency of the boiler is also closely related to the heating area. The larger the heating area, the better the heat transfer effect, which will increase the boiler thermal efficiency linearly, make the fuel utilization more complete, and the gas consumption cost less.
4. Boiler output
The output of a 1 ton boiler is 600,000 kcal, and this data is fixed.
How to reduce the gas consumption of gas boilers?
There are two main factors that cause high gas consumption in gas boilers. One is the large boiler load; the other is the low thermal efficiency of the boiler. To reduce air consumption, we must start from these two aspects.
1. Influence of boiler load
In the absence of measuring instruments, we measure the heat output according to conventional knowledge. When the user's demand for the boiler is unstable, the boiler consumes more heat and the load increases.
2. Influence of boiler thermal efficiency
There are many influencing factors in terms of boiler thermal efficiency. We list some common points. You can check against your own boiler equipment.
(1) The water quality of the boiler feed water is not good, and a lot of scale is accumulated after long-term operation, and the heat transfer efficiency of the heated surface is lowered. The thermal resistance of scale is 40 times that of steel, and the 1mm scale will increase fuel consumption by 15%.
(2) Ashing on the outer surface of the heated surface also increases fuel consumption. The furnace can be turned on to check the ash scale, or it can be determined by detecting the exhaust temperature.
(3) The boiler has a serious air leakage. Excessive cold air enters the furnace, and the oxygen content of the flue gas rises. When the smoke oxygen meter detects that the oxygen content of the flue gas exceeds 8%, excess air will appear and the heat loss will increase.
(4) The gas quality is lowered and the concentration is lowered. This requires a professional boiler technician to carry out a specific analysis.
(5) The burner automatically adjusts to failure. The burner mainly controls the combustion condition by automatically adjusting the "air-fuel ratio". If the sensor or computer program is unstable, although the combustion is normal, it will cause "chemical incomplete combustion heat loss". The combustion flame can be observed, the red fire represents poor combustion, and the blue fire represents good combustion.
The condensing gas boiler produced by FANGKUAI Boiler adopts advanced condensation technology to set up a condensing recovery device near the flue. When the high-temperature flue gas passes through the device, the latent heat part encounters the condensed water to release heat, which is provided to the boiler for absorption again. The thermal efficiency can be It is 98% high; it can save the company the fuel input cost of 50,000 to 100,000 yuan depending on the boiler capacity and maintenance quality.
With the boomingdevelopment of the mobile Internet industry, new technologies, new services and data centers are becoming more and more closely related, and all walks of life are growing rapidly in the "cloud". The massive data processing needs make the Internet industry face new challengesof the era of comprehensive cloudification of data storage and transmission modes.
