AMD Power were to buy 10 tons of steam and one 4 tons of steam condensing steam boiler maintenance fuel gas from the company for cell processing company production and construction. From the analysis of the demand to the boiler factory, by the company solely responsible for AMD Power fully demonstrated the company's confidence in me, the smooth progress of bilateral cooperation.
Case 3, in the rear of the boiler maintenance did not take anti-corrosion measures or condensation water collection, etc., gas boilers should avoid long-term operation at low load or low-parameter case.
4, the combustion gas boiler adjustment process, to ensure the quality of the combustion, exhaust components must be detected in order to determine the excess air and incomplete combustion. Generally, the gas-fired boiler during operation, the carbon monoxide content should be less than 100 ppm, and at high load operation, the excess air ratio should not exceed 1.1 to 1.2; under low load conditions, the excess air ratio should not exceed 1.3.
5, fireman switch should always pay attention to the case of the gas valve. Gas line not leak, if unusual circumstances, such as the boiler room abnormal odor, not open burners, ventilation should be checked to exclude odor, check valve, the normal operation may be started up.
6, a gas boiler for liquid fuel with air, special attention should be ventilated boiler room. Because of severe liquid gases than air, in case of a leak can easily cause condensation of liquid and spread on the ground, resulting in a vicious explosion.
7, after a period of time or inspection line outage, when the single-column hydraulic machine into operation again, should open the vent valve, bleed time, deflation time should be determined according to the length of the pipeline and the gas species. If a longer boiler downtime, it should cut off the gas supply valve, close the vent valve.
8, the gas pressure is too low and not too high, to be run within the set range, the specific parameter provided by the boiler manufacturer. When the boiler running for some time, found that the gas pressure is below the set value, it is timely contact with the gas company, gas pressure if there is a change. Burner operation for some time, should be checked line filter is clean, as a lot of pressure drop, there may be too many impurities in the gas, the filter is clogged, washing should be removed, if necessary, replace the filter.
9, should comply with boiler manufacturers operating instructions provided by the manufacturer and the burner, and the description should be placed in a convenient place for easy, for inspection. There are exceptions, when not solve the problem, depending on the nature of the problem should promptly contact the boiler plant or gas company, to conduct maintenance by a professional maintenance staff.
When selecting and purchasing boiler maintenance sensors, we should consider which types of boiler sensors should be determined according to the measuring object and the measuring environment. The principle of the sensor must be considered first, which requires an analysis of various factors before it can be determined. According to the characteristics of the sensor to be measured and the conditions of use of the sensor, consider the following specific issues, the size of the measuring range, the measured position of the sensor volume requirements, the measurement mode of contact or non-contact, the method of signal extraction, Wired or non-contact measurement, the source of the sensor is imported or home-made and many other factors. The second is the choice of the sensitivity of the boiler sensor, usually within the linear range of the sensor. The higher the sensitivity of the sensor, the better, when the sensitivity is high, the output signal corresponding to the measured change is larger, which is beneficial to signal processing. The sensitivity of the sensor is directional. The sensor with low sensitivity in other directions should be selected when it is a single vector and its directivity is high. If the sensor is measured as a multi-dimensional vector, the lower the cross-sensitivity of the sensor is, the better.
Xiao Bian has talked to you before, the internal gas boiler maintenance room layout requirements, not only that, the external gas boiler room selection, there are also certain requirements, together with the many in order for gas-fired boilers to achieve great efficiency. Today, small series to tell us something about the external gas boiler room siting requirements.
