gas industrial vacuum hot water boiler

Maintenance and corrosion protection of a hot water boiler, water supply oxygen due to some timely accumulation of dissolved oxygen corrosion of hot water boiler will result in increased water supply process, therefore, at the same time equipped with the appropriate oxygen equipment should be better the efforts to control the entire water supply. The oxygen present embodiment mainly sodium sulfite chemical reaction oxygen, this effective method of oxygen can fully reduce the overall corrosion to metal. Meanwhile, some capacity is relatively increased water boiler, may also be employed in high vacuum or low oxygen equipment, a reasonable way is to use hot water boiler air evacuated, forming a gas hot water boiler pressure less than atmospheric pressure will reduce air leakage phenomenon occurs, play a good maintenance effect. Second, strict control of the pH of the boiler water in accordance with the regulations of the country, the pH of the boiler water is controlled within a predetermined range, this can be well protected by film formation, avoiding corrosion of the metal walls of the hot water boiler . Case of pH value rises or falls appear outside the furnace, to take timely measures to maintain, when the entire index is below 10, you can put some alkaline agents on the hot boiler to an appropriate increase to a normal pH, can also be run by using trisodium phosphate and sodium hydroxide to adjust the dose to accurately control the pH of the water throughout the furnace, so that, to maintain good control effect, helps to reduce boiler corrosion, build clean and efficient mode. Third, strengthen the maintenance of boilers disabled during shutdown, such protective measures are not taken, the boiler water and steam system of the metal surface corrosion is dissolved oxygen, since the boiler generated during operation is an alkylene iron corrosion products compounds, can become disabled at the time of high iron oxide compound, which makes corrosion process is repeated down the line. And therefore must take appropriate protective measures during boiler shutdown is disabled, avoid and mitigate corrosion of the boiler. Maintenance of two ways: First, dry maintenance, and second, wet maintenance Wet maintenance Currently we have taken as follows: (1) the pot of water after shutdown exhausted, remove scale, impurities and soot. (2) off (or blocked with the blind plate) each of the ducts of valves connected to the boiler. (3) The demineralized water injected into the boiler to a minimum level, with special preparation of a good basic corrosion pump liquid injected into the boiler. (4) When all the injection liquid corrosion boilers, boiler water supply valve is turned on, the boiler filled with demineralised water until the pot of water drained out from the valve, closing the valve and emptying the water supply valve. (5) Open special boiler water circulation pump, so that everywhere in the boiler alkaline solution concentration uniform corrosion. (6) During the maintenance, you should always do external examination, and regularly testing pot with water, and liquid or alkalinity level drops, should identify the reasons for timely processing and additional liquid. (7) periodically open water circulation pump, the liquid concentration consistent throughout. (8) during the wet winter maintenance of the boiler, the boiler temperature must be kept above 5 ℃ and do the following. a. during the entire maintenance, raw Microflame oven regularly in order to maintain the outer surface of the heated drying. b. To start a regular water circulation pump, the concentration of the solution is consistent throughout. c. also regularly take the solution testing, if the alkalinity is reduced, should be supplemented. d. Winter freezing measures to be taken. Conclusion of people using the hot water boiler in the current society continues to increase, for the maintenance and repair of hot water boiler has been people's attention, but at a certain point of view, people are now plagued by the boiler normal use of the main factors that boiler corrosion situation occurs, this corrosion occurs not only will make the life of the boiler there is a certain decrease in the safety of the boiler will make a corresponding reduction, so this needs to boiler rusting conduct a comprehensive analysis, and in accordance with the results of the analysis put forward countermeasures boiler fundamental Rusty effective solution, so that the development of China's water boiler to get some protection.

Recently, Shandong Province, issued a "thermal power plant air pollutant emission standards (DB37 / 664-2019 instead of DB37 / 664-2013)". Standards will be implemented on September 7, 2019.

First, the standard applicable to the use of a single output 65t / h or more layers in addition to coal-fired burner, furnace stoker boiler or steam generator; single output 65t / h or more oil, gas, or steam generation boiler; single output 65t / h or more power using steam boilers other fuels; pulverized coal fired boilers of various capacities; various capacities gas turbine. Gas turbine integrated gasification combined cycle power generation is performed in this standard gas turbine exhaust gas as a fuel limit.

Environmental Impact Assessment II. This standard is applicable to the existing project management of emissions of air pollutants, as well as the above-mentioned new construction, renovation, expansion projects, environmental protection facilities design, environmental protection facilities acceptance, pollution permits and air pollutants after putting into operation emissions management.

Vertical steam boiler optional indirect heat exchanger Typically, conventional vertical steam boiler simple alterations, such as waste heat recovery apparatus according to the installation, can improve energy-saving effect, which is actually a vertical steam boiler saving advantages. Vertical steam boiler heat exchangers are commonly divided into two categories, one is a contact touch exchanger true, then the other is simply a plate heat exchanger. They smoke waste heat is used to acquire, improve energy saving effect of separate devices. Vertical high vacuum steam boiler indirect contact heat exchanger thermal efficiency, the dust sources is also removed, acidic water body, lossy vertical steam boiler. Plainly equipment acquired energy from the cold dust in the suspect be indirect heat exchanger door is what I always say. Today, many people choose with vertical steam boiler, market share continues to increase. Such vertical steam boiler soot emissions in with a lot of water vapor, according cold suspect emit large quantities of latent heat of vaporization. The rate is much higher than coal-fired boiler coal-fired boiler. Good selection of such vertical steam boiler connected to a heat exchanger Jane effect
