How do gas-fired steam boiler usas need to be maintained when they are not in use?

Nowadays, the use of gas-fired steam boiler has become more and more frequent, and the boilers all over the country have changed the use of gas-fired boiler with each passing day. Although the domestic professional gas-fired steam boiler is stable in operation and less energy-saving and consumption-reducing in sewage discharge, it is necessary to use proper maintenance in the case of long-term non-use in order to carry out normal use. Specific gas-fired steam boiler maintenance methods in the case of not in use and see below for detailed analysis of the following:

1: dry maintenance of gas-fired steam boilers should remove the boiler water after shutdown, and then thoroughly remove and rinse the dirt from the interior. And keep the oven dry so as not to be seduced. You can dry the chamber with a light fire, but not with a fire. Also be careful to close all hand-hole piping valves and place the quicklime tray in the drum. Check the boiler at least three months without using a gas-fired steam boiler for a long time. If the quicklime in the chamber is crushed into powder, the new lime needs to be replaced immediately to ensure that the drying protection in the furnace of the gas steam cooker is not corroded by moisture.

2: in addition to dry maintenance, wet maintenance of gas-fired steam boilers can also be done by means of wet maintenance, which is to remove internal dirt after discharging the water in the furnace, and to fill the chamber with treated water and then heat it to the required temperature. The gas in the water is then discharged out of the furnace and all valves are closed. In this way, the furnace is filled with water to complete maintenance. Of course, wet maintenance should not be used in cold weather to prevent water icing and damage to the tank. It can be seen that the gas-fired steam boiler in the case of not in use is mainly dry and wet method of maintenance, which kind of specific use Maintenance method according to different site and climate conditions to make flexible choice.

The purpose of the transformation of low-impact boiler boiler load operation after the first, to the transformation of the boiler boiler can meet the national emission standards, and second, for the boiler safe, smooth and efficient operation, but it is inevitable that due to differences in the specific circumstances, but also there will be such a problem of low load operation of the boiler is one of the issues one way or another, which, then, operating at low load boiler exactly what kind of harm? (1) boiler in a state of low load, there will be combustion instability, easy to adjust, and many other problems caused by boiler flameout phenomenon, affecting the normal production. (2) low load state of the boiler, the temperature of the furnace will decrease, incomplete combustion boiler phenomenon occurs, reducing the thermal efficiency of the operation. Low-load operation (3) boiler to some extent, can also cause damage to the water cycle. (4) long-term operation at low load, the exhaust gas temperature of the boiler can cause decreased, an increase in the probability of occurrence of heat exchange tubes of the rear low-temperature corrosion. In short, after the transformation of the boiler, the boiler must pay attention to prevent the phenomenon of low load operation occurs, possible trouble.

"Green Castle is the gold and silver mines," Mianyang City, Sichuan Province to respond positively to President Xi's philosophy of environmental protection, strengthen the construction of ecological civilization, and vigorously promote the city's air pollution control, focusing on small boilers county level and above cities out of coal, comprehensive enhance the transformation of 20 tons of steam / hour or more coal-fired boilers, let Mianzhou earth, the sky bluer, and more green, the water clearer.

In advance of the phase-out of coal-fired boilers, the city's focus on top-level design, in June this year issued a "county-level and above Mianyang urban area small coal-fired boilers work out program," clearly take demolition, renovation, clean energy alternatives and other measures , before the deadline to the end of March 2019, phasing out the county level and above urban area 10 steam tons / hour and the small coal-fired boilers (because of the promotion of cogeneration of small coal-fired central heating boiler replacement must be before the end of 2020 total phase-out). Not included in the program for the elimination of the objectives and tasks of various types of small coal-fired boilers, find an out of one.

Eliminate small coal-fired boilers for improving urban air quality has a positive effect. In Mianyang, a wine business one step ahead, we tasted the sweetness: switch to phase out coal-fired boiler gas boiler. Before coal-fired boilers, the company must invest a lot of money each year to buy coal used in the treatment of fly ash and slag above, and coal combustion will bring countless pollutants.

After starting gas fired boiler to boiler project, which began to corporate purchase and install a gas boiler, energy-saving cooking pot bottom, ice bucket, multi-cooler tube array, sewage tank 58 and other equipment (sets); and in 2017 December formally put into use. After coal to gas, coal storage area is no longer required, cinder storage area ,, new construction land for the enterprise, greatly reduce production operating costs. "

This year the city built-up area of ​​the city's coal-fired boiler phase-out targets small task is 25 units. City Commission by letter, the Environmental Protection Agency, Bureau of Quality Supervision and other relevant departments to strengthen organizational leadership, establish long-term working mechanism, compaction work responsibilities, in close collaboration to promote the division of labor, and strengthen supervision to ask efficiency, strict examination and approval for the record, put an end to new coal-fired small boiler, strengthen propaganda and guidance, do a solid job of work to promote the service. As of the end of November, this year's phase-out plan included 22 small businesses of 25 coal-fired boilers have completed 24 units, of which the use of special equipment to complete the cancellation of the registration certificate of 17.

City Commission by letter the person in charge, the next step, they will actively cooperate with relevant departments to intensify its efforts to strengthen the county has not yet out of the task of supervision and corporate efforts to accelerate the phase-out of the boiler has been using special equipment write-off registration certificate , guidance throughout the solid performance of the late acceptance procedures, and make due contributions to effectively improve the quality of atmospheric environment in Mianyang.
