How to reduce the scale of known gas steam boiler steam boiler heating surface of the machine is the primary supply of high quality steam. Past, steam appeared to mankind brought great changes. The emergence of the steam era of human civilization introduced the modern era. Now there steam boiler once again that human potential is unlimited, it appears there are a lot of people to help. Steam boilers plays an important effect on people's day in. It's like bathing, eating, and other industries. It is said that the local demand for steam boiler steam demand. Steam boiler steam supply is the primary tool. Industrial production in the steam boiler to supply steam for the people, with the production of human power supply, making it easier to produce in the production. In the days of steam boiler supplying steam can help people make food, why we can take a bath with a steam boiler in the cold winter. These are to help supply the steam boiler. Steam boiler steam can easily supply better for us to make our life easier and more convenient. About steam boiler, we should be careful when they use their maintenance work, so that it can help us longer. Steam boiler in direct contact with the heat exchanger, the high heat recovery, contaminants in the flue gas are also removed, but acidic water quality, which is not convenient for the fired condensing water tube hot water boiler manufacturers. The so-called direct heat exchangers is that we often call for means for recovering heat from the flue gas condensation. Now, more and more people choose to use the steam boiler, the share of the market share continues to add. Flue gas discharged from the steam boiler containing a lot of water vapor, is condensed through the release of a lot of the latent heat of vaporization, which is more than a coal-fired boiler. a lot of. This boiler better selection of direct heat exchanger. Industrial production is the primary driving force of the world expanded, is very important for the expansion of the world. Therefore, we need to use steam boiler supplying steam better for us, because of our human expansion needs of these sophisticated machines help. No machine age is primitive society. When humans learn to use tools, it marked the beginning of civilization has already begun. Steam boiler is a tool we humans can do to help expand. No matter how preparedness, gas steam boiler, after working long hours, more or less will have some scale. Gas steam boiler is in operation, the furnace will be a series of chemical and physical reactions, the application process, will form a strong and fine scale on the heating surface, which would lead to a direct heat exchange efficiency of the boiler decreases; and by the effects of corrosion under the scale, will lead to reduced water wall furnace heat absorption gas steam boiler, then dropped thermal efficiency, waste of capital investment. The necessity of finishing scale there is little that is durable stable job and let the boiler down. As long as the thermal conductivity of the scale of one percent of the steel, once the heating surface fouling, so that the heat transfer will be impeded, in order to maintain the boiler must be output in the use of the process, it is necessary to progress the fire-side temperature. Process outlet temperature of the furnace gas steam boiler making added, so it will make the loss of added gas steam boiler, reducing the heat transfer effect that it would be useful after fouling equipment in the water wall, so it is very likely Add water wall tube wall temperature can cause lead to burst pipes water wall. Cleaning the boiler becomes particularly important. Performing the cleaning process, you can use efficient, environmentally friendly and non-corrosive cleaning agent, so that the device will reveal the original metallic tube, down to fouling. Secondly, in the incinerated gas steam boiler, furnace needs careful investigation smoke temperature and the temperature of the main steam changes; when the main steam pressure in the rising condition, if the boiler burning smoke temperature rise speed or does not rise significantly Pianman, immediately Check the oil gun fire situation.
