The gas-fired steam boiler is used widely and meets the current environmental protection standards. What are the parameters of a set of 2 tph gas-fired steam boiler and what are the gas fuels?
Whether the water quality in the gas-fired boiler reaches the required standards is directly related to the safety, performance and service life of boiler. The water must be treated before the boiler operation. However, what are the water quality standards for the gas-fired boiler?
If the boiler gives overpressure indicator which affects boiler's safe operation, depressurization measures should be taken. However, please pay attention that depressurization can not be too fast. After the overpressure problem of steam boiler is solved, we should check the internal and external parts of boiler to ensure that everything is going well.
In order to further improve the working performance of oil-fired boiler, many customers require galvanizing processing of furnace body. However, is it really effective?
In the adjustment of boiler operation, on the basis of ensuring safe operation, economic operation must also be achieved to improve boiler efficiency. In general boiler units, the efficiency can basically reach more than 92%, and the total loss is less than 8%. The loss is: exhaust heat loss, generally 5-6%, followed by mechanical incomplete combustion heat loss is less than 1-1.5 %, heat loss and ash slag physical heat loss are about 1%. (Physical heat loss for high ash coal ash residue will be greater).
From the point of view of quantification of indicators, the key to improving boiler efficiency is to reduce smoke loss and heat loss due to incomplete combustion of machinery. Pay attention to the flue gas temperature changes. Excessive flue gas temperature will affect the efficiency of the boiler. Too low temperature may cause low-temperature corrosion of the air preheater. Therefore, it is necessary to strengthen the adjustment according to the load changes during operation. When t
Industrial boilers will produce wastes that needs to be treated during the use process, which is what we mentioned of boiler blowdown. What are the methods for boiler blowdown?
1. Regular blowdown
1) The time interval and quantity of discharge depend on the test results of boiler water. It usually do not exceed 5% of the water supply.
2) When the regular blowdown is being made under high load of the boiler, the blowdown of the water-cooled wall header is generally not required to avoid affecting the normal water circulation of the water-cooled wall and forming a tube explosion incident.
2. Continuous blowdown
The amount of blowdown shall be determined according to the test results of the boiler water, and shall be completed by adjusting the needle-shaped angle of the blowdown tube.
