water tube heavy oil steam boiler

How to reduce the scale of known gas water tube 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 hot water boiler. 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.

Gas boiler safe operating procedures: gas-fired boilers this kitchen I believe we are not unfamiliar fishes it. But this thing is not so easy, and sometimes improper operation causing very serious consequences, so the gas boiler rules is very important. That in the end this is how the specific operation of it, if you want to know, quickly told us with a look. 1. All personnel must be familiar with the operation of the boiler performance and safety knowledge of the boiler operating certificates. This post is strictly prohibited non-operating personnel. Duty should be strictly in accordance with the operating records and do a good job shift recording, the security situation and the device should shift change operation tests, carried out. When the shift to check the boiler is intact. 2. Boilers and safety accessories should be inspected, and in the period. 3. Kai blast furnace gas furnace ready ① Check if the gas pressure is normal, not too high or too low, open the door of oil and gas supply section; ② Check whether the pump Sheung Shui, or opening the purge valve, until the Sheung Shui so far. Open the Water Supply System for each section of the door (front door section Sheung including pumps and boilers); ③ check level gauge, the water level should be in the normal position, the water level gauge, a water level required color plug in the open position, the water level to prevent false, if water can be manually Sheung; ④ check valves on the pressure pipe, must be opened, the wind deflector must all flue opening; each knob ⑤ checks the control cabinet are in their normal position; ⑥ water tube steam boiler check valve should be in the closed state hot water boiler circulating pump outlet valve should be turned off; ⑦ checking water softening equipment is operating properly, a variety of indicators to create a soft water meets national standards. Open the power ⑴; ⑵ startup burner; ⑶ purge valve on the drum, is completely out of steam, the off; ⑷ inspection hole into the boiler, and the hand hole flange valves, the leak was found to be fastened, tight as the solid leakage maintenance shutdown; ⑸ pressure rise when 0.05 ~ 0.1MPA, replenishment, sewage, water supply systems and sewage screening test device while flushing water table; ⑹ when the pressure was raised to 0.1 ~ 0.15MPA, flushing pressure gauge trap; ⑺ when the pressure was raised to 0.3MPA, "fire load / small fire" knob to "fire" to strengthen the combustion; ⑻ when the pressure was raised to 2/3 of the operating pressure, start warming air supply tube, slowly open the main steam valve, to avoid water hammer; ⑼ drain valve is completely closed out of steam; ⑽ after all the drain valve closed, slowly open the main valve to open, and then half a turn; ⑾ "burner control" knob to " Auto "; ⑿ level adjustment: adjusting the water level (to manually start and stop the pump) according to a load, low load level should be slightly higher than the normal level, high load level should be slightly lower than the normal level; ⒀ steam pressure adjustment: adjusted according to a load combustion (manual adjustment Fire / small fire) ⒁ combustion state determination, determines the amount of fuel atomization air ⒂ observation condition exhaust gas temperature, smoke, temperature control is generally between 220--250 ℃ The flame color, smoke color, while observing the chimney exhaust gas temperature , concentration, adjusted to the optimum combustion state. ⑴ Open the power; ⑵ start the circulation pump; ⑶ slow circulation pump outlet valve; ⑷ startup burner; ⑸15 min "" Load fire / small fire "bit color button is turned to" fire "" ⑹ "burner control" knob spin to "automatic." 5A normal shutdown: hot water boiler ① "fire load / small fire" knob to "small fire"; ② off the burner; ③ close the fuel supply valve; ④ ⑤ closing dampers boiler after the temperature dropped to 50 ℃ , the circulation pump outlet valve closed. ⑥ stop circulation pump

Note the fuel gas-fired boiler fuel gas pressure when the talk about fire boiler shutdown in accordance with the fuel (electricity, oil, gas) can be divided into electric water tube steam boiler, steam boiler fuel, gas steam boiler three kinds; in accordance with the constitution can be divided into vertical steam boilers, horizontal steam boiler, steam boiler, mostly small and medium sized single, double the return of the vertical structure, large steam boilers and more horizontal structure of three return. The following is a pressure Cautions fire boiler 1 shutdown, shutdown pressure fire more than 6h, main steam valve should be closed after the pressure of the fire over time, open trap superheater outlet header of the superheater to cool. After closing the main steam valve, such as pressure goes up, and can be used at the same time into the sewage Boiler Feed down method. When the recovery boiler operation, subject to step-up and step 2 protection, thermal shutdown during the press pot still steam pressure, it must still pay attention to monitoring, and to allow the boiler to maintain the water level 3, with a cast iron gas boiler province, in after stopping the boiler feed water, the shutter should be closed save flue gas, furnace bypass channel open flap or in the circulation pipe, stopping the gas temperature exceeds a predetermined value within the province 4, the pressure during the shutdown should be appropriate fire sewage, furnace exclude precipitation Care was taken after pressure fire shutdown should not immediately stop the operation of the circulating pump, the network should continue circulating water circulating in the system for some time, when the boiler outlet water temperature dropped to 50oC with the following, in order to stop the operation of the circulating pump
