Ovens and boilers boiler inspection methods oven to cook and cook blast furnace blast furnace inspection can be found as soon as possible the existing boiler problems and avoid boiler safety accidents in use, today we are speaking about the oven and cook for blast furnace boiler the inspection methods: 1, chain grate cold test run more than 48 hours. 2, coal gate installation is completed, the shutter plate on the coal should be closely good coverage, and other impurities to prevent leakage into the coal, coal stuck up and down the shutter, the shutter connected to water cooled coal, firing the door open and flexible. 3, boiler and subsidiary equipment Ge all assembled and pressure test qualified. 4, the end of the furnace wall masonry and insulation, and check whether the debris inside the flue cleaned. 5, thermal instrumentation boiler should check eligibility, and check the reliability of the boiler feed water, as well as water to the boiler to full level. 6, the required auxiliary oven test run is completed, such as pumps, fans, etc., have confirmed that each part of the work safety conditions to start, you can start the oven. 7, the furnace wall should be installed measurement points or sampling points. 8, all moving parts and should be required to add oil cup oil. Learn how to do the oven and cook blast furnace boiler inspections, I believe you must have learned a lot of knowledge of it, I hope this can help you use the more secure the boiler.
The meeting of "open innovation, create brilliant" as the theme, highlighting the fast boiler open to innovation-oriented, and look forward to dealers around the partners jointly casting a bright future for the fast side of tomorrow's development goals. Mr. Lu Haigang president issued a welcome speech, reviewed the party and lead the fast group since its inception, all the way through the clutter, to ride, to now become a memorable moment every premier industry leader in the clean boiler market.
Boiler cleaning the necessity and significance of the boiler after a long run, the inevitable emergence of scale, corrosion problems, these problems are due to the generation of scale, so that the heat transfer deterioration, resulting in reduced efficacy boiler. It is difficult to achieve nominal evaporation; and since the heat transfer is deteriorated, such that the metal overheating, under pressure boiler, furnace tube bulge occurs even explode; poor thermal conductivity, so that the fuel consumption is increased, increased operating costs, boiler shortened life expectancy. Therefore, the boiler scale, should take the necessary cleaning methods. Of the boiler system operated at optimized state, it must be specialized chemicals treatment of boiler system water system: to remove scale, rust and anti-corrosion treatment: 1 chemical cleaning: adding a chemical cleaning agent to rust in the system , dirt, cleaning oil dispersion is discharged, reduced to clean metal surfaces; 2, routine maintenance: boiler scale inhibitor is added, to avoid rusting of metal, to prevent the crystalline precipitate calcium and magnesium ions. Boiler cleaning in two parts, part of convection boiler tubes, superheater tubes, air heaters, waterwall tubes scale, rust cleaning, i.e. water boiler water treatment, we used the final Li Jing Ling descaling operation, neutral cleaning technology cleaning operation, relatively low cost; cleaning of the part of the outer tube, i.e. the cleaning of the boiler furnace, we used high-pressure water jet cleaning technology, it is possible to achieve good results. 1, the cleaning operation may be neutral at neutral or weak alkalinity (pH 7-12) conditions, the water does not change the operation of the boiler a predetermined state index, do not stop cleaning, cleaning can reduce the loss caused by the stop, this is a the only signs of cleaning. 2, security theory and practice of running the boiler have proven non-erosive, washed acid-free cleaning under neutral conditions, the corrosion rate is less than the water washing of the corrosion rate of the metal, no corrosion damage to the metal. 3, non-toxic and pollution-free operation of the Spirit is a green cleaning products, boiler blowdown COD after its cleaning. BOD. The pH full compliance with national standards. 4, easy to use drugs added to the water supply can be, without a separate professionals, post operator can operate, it can be widely used. 5, a significant saving, the cleaning process in which water is the normal production water, unlike dispensing additional consumption pickling, passivation, and a large number of repeated washing of freshwater resources consumed. High pressure water jet cleaning technology uses water as the medium, so that the water system by special equipment to produce multi-beam, multi-angle, high-pressure water jets of different intensity. Internal cleaning object fouling, plugging, or be completely cut surface adhesion, crushed, pressed and washed in order to achieve complete cleaning. Whatever the fouling deposits, high pressure water jet cleaning device for cleaning, can be completely removed, which considerably metal color. It does not require chemicals, or corrosive flux, safety, and environmental protection. Boiler air preheater, waterwall, superheater, economizer heating surface and the like due to clogging of the exhaust gas temperature, boiler efficiency is lowered, increasing the wind electrical energy consumption; the fan will cause severe blockage afford pulling negative pressure oxygen furnace not enough, boiler forced outage. Using high pressure water jet technology, the cleaning effect is obvious. Equipment from high pressure water pump, water hoses, high pressure gun, special nozzle and other components. Cleaning process: water pressure via a high pressure pump to the 50 ~ 100Mpa, via line transferred to the system actuators work surface, forming a bundle of fine high-pressure water emitted from the nozzle with a high pressure water jet but powerful strike capability, which exit velocity up to 380m / s, the heating surface fouling rinse. The high pressure cleaning technology to clean, easy to adjust, cleaning equipment to be non-corrosive, non-polluting the environment, the effect is obvious characteristics, is an effective and a good way to save money and effort, especially suitable for solving air preheater clogging, severe coking furnace heating surface slagging problems. Generally reduce exhaust gas temperature of 4 to 12 degrees, the main improved reheat steam temperature of 0.5 to 5 degrees, to reduce electrical energy consumption for the wind, and early detection of creeping inflation, under scale corrosion risks, the unit safe and economic operation of very help.
10 tons WNS-type gas heating boiler price is how much money? District, urban heating First, there are two ways of heating coal-fired hot water heating, and second boiler heating fuel gas, fuel oil and gas boiler heating is gradually replacing coal-fired boilers to be the main way of heating the moment, (the main reason can refer to gas-fired boiler and the difference between coal-fired boiler).Free Chat
