FAQ With Boiler - FangKuai Boiler

1. When it is found that the boiler has an abnormal phenomenon and the safety control device fails, the emergency disconnect button should be pressed to stop the boiler operation;

2. If the boiler feed water pump is damaged and the mediation device fails, the emergency disconnect button should be pressed to stop the boiler operation;

3. When there is a problem with the electricity and fuel, the push-off button should be pressed;

4. When there is a danger to the boiler or personal safety, emergency shutdown should be adopted.

Operation sequence of gas boiler in case of accidental shutdown

1. Quickly close the main steam valve to prevent the drum from losing water;

2. Turn off the main power switch and the natural gas valve;

3. Close the boiler surface drain valve to prevent other faults in the boiler;

4. Turn off the oxygen supply valve of the deaerator;

5. According to the normal shutdown sequence, check whether the boiler fuel, steam and water valves meet the requirements for shutdown.

How to properly handle gas boilers during temporary power outages?

Superheaters and reheaters are an important part of gas boilers, both of which increase steam enthalpy and thus increase boiler thermal efficiency.

The function of the superheater is to heat the saturated steam to superheated steam having a certain temperature.

The function of the reheater is to heat the exhaust gas of the high pressure cylinder of the steam turbine to a reheating temperature equal to (or close to) the temperature of the superheated steam, and then send it to the intermediate pressure cylinder and the low pressure cylinder for expansion work.

Popular science: What is the role of superheaters and reheaters in gas boilers?

Under normal circumstances, considering the factors affecting the selection of gas heating boilers, the heating area of 10,000 square meters probably requires about 3.6MW of hot water boiler capacity, but this is the ideal situation, the conversion of 3.6MW gas hot water boiler is about equal to 5 Tons of hot water boilers. But here is a good news, the 1 ton boiler produced by FANGKUAI Boiler can basically meet the heating area of 10,000 square meters. This is very good data. After all, the larger the tonnage of the boiler, the higher the boiler price. If it is in an extremely cold area, and the heating building is an old building, the capacity of the gas boiler to be used will increase, and even a 7-ton, 8-ton hot water boiler may be required to ensure the indoor temperature that the user wants to achieve.

Heating area is 10,000 ㎡, what’s the thermal power of a gas boiler should be chosen?

Assuming that the 10 ton/hour gas hot water boiler costs 500,000 RMB when purchased, the annual depreciation of the boiler is: 500000-(500000*5%)/10 = 497500 RMB.

Assuming the residual rate is set at 5%, and it is expected to use 10 years, then the annual depreciation rate of 10 tons/hour industrial gas boiler = (1-5%)/10*100% = 9.5%.

The monthly depreciation rate of the 10 ton/hour gas hot water boiler is 9.5% ÷ 12 = 0.79%.

The monthly depreciation of the 10 ton / hour gas hot water boiler = 0.79% * 500000 = 3950 RMB= 571.5US dollars.

What is the depreciation charge for a 10 ton gas hot water boiler?

Gas consumption per hour of natural gas boiler = boiler thermal efficiency / natural gas calorific value / boiler efficiency.

Through the formula we can see that the gas consumption of natural gas boilers mainly depends on boiler capacity, natural gas calorific value and boiler efficiency. However, we cannot change the boiler capacity and natural gas calorific value, only the boiler efficiency is variable.

Taking a 1 ton gas boiler with full-load operation as an example. If the calorific value of natural gas is calculated according to 8000 kcal per cubic meter, according to the difference of boiler efficiency, it is calculated that 1 ton natural gas boiler consumes about 75 cubic meters of natural gas per hour.

The higher the efficiency of boiler use, the less gas consumption, which has inverse relationship between the two. Boiler efficiency has become a key point in assessing boiler quality.

What is the gas consumption per hour of a 1 ton natural gas boiler?

The range of industrial boilers is very wide, and boilers are needed in industries such as chemical, food, power plants, textiles, paper, and metallurgy.

Industrial boilers are often referred to as industrial steam boilers, industrial hot water boilers and other equipment. Fangkuai boiler is the pioneer in the field of gas boilers and electric boilers. Industrial boilers can be made into different tonnages of 0.5 to 130 tons according to demand.

There are more than 200 types of FANGKUAI Boiler. If your company has a demand for industrial boilers, please feel free to call.
