Increase efforts to promote green buildings, new buildings full implementation of green building standards. In deepening the industrial pollution control, referring to Beijing and Xi'an subsidies, launched a comprehensive transformation of low nitrogen gas boiler. Before the end of 2019, the district completed at least 50% of the area within the low-nitrogen transformation tasks 10 steam tons / hour or more gas-fired boiler.
Gas what do you mean by high pressure boiler room construction principle: At present, gas steam boiler, gas hot water boiler is widely used in all walks of life, in order to ensure the safe operation of the gas boiler, the user must consider the full range at the time of the construction of the boiler room.
Condensing what do you mean by high pressure boilers to buy four issues introduced! Condensing boiler as the new darling of the new era, as opposed to ordinary gas boiler, it is not only efficient and more environmentally friendly, more and more sought after by everyone, especially for large size house is very beneficial. But many people are not familiar with condensing boilers for daily purchase often encounter the following four major issues, we now take a look at it. 1, the area is not all units are suitable for installation of the condensing boiler? Condensing boiler top-ranking company Company: home improvement applications, for only about fifties square meter apartment, it also suitable for installation condensing boiler? This may be a false proposition, but the fact is some heating company "comprehensive" sell condensing boiler, regardless of the size of apartment owners, this cost-effective account changing, so this is we need to analyze specific issues are. 2, the premix is not necessarily much better than the secondary condensing heat exchanger? Many in the industry have a secondary heat exchanger condensing furnace scoffed, calling it "false condensation", but warm cubic noted that secondary condensing heat exchanger efficiency is more than 100%, belongs to the category of energy efficiency, but the overall thermal efficiency than the full premixed low a few points. 3, it is not just any company can install condensing furnace? Is not a conventional boiler and installation, as any company can without professional training on the installation of condensing furnaces it, condensing furnace installation, post-maintenance, maintenance of what are different, buy boilers, pay attention to manufacturers, industry bodies are there supporting the training or evaluation or certification system, when we choose a condensing boiler company, we are to consider these points. 4, why so many condensing boilers more expensive than a conventional boiler? Price condensing boiler almost every HVAC company's biggest obstacle in the promotion, total view of the current market, almost all brands of premix condensing boiler furnace than the conventional market price of expensive, where are you in this? Or that question, your initial cost and maintenance cost, is not all house area, all the habits and conditions, can recover the cost of expensive, depending on the price list condensing boilers companies the choice of owners, it is the country "energy saving" made a great contribution. The above is an optional four difficulty condensing boilers often met in everyday life, hope can help to you in life. In fact, regardless of whether the installation is in life, condensing boilers or will other things, many times we need to meet their own reality, in order to select the more effective side, remember herd mentality, blindly follow the trend.
Corrosion causes and methods what do you mean by high pressure boiler boiler corrosion is often used in the home or small-scale industries, there will be worn at the time of its use or corrosion is inevitable, but this phenomenon is caused by loss of equipment will give, I give below describes the reasons of corrosion and methods of its corroded: common corrosion forms superheater tubes and reheater, high-temperature furnace: a, a gas side corrosion, corrosion gray matter. 2, anti-corrosion method: controlling the temperature of the furnace tube, the melting point of the condensate is skipped, deferred control the oxygen content and surface treatment selected tube control, reduce the combustion of sulfur produced. 3, dew point corrosion: SO2 gas generated by the combustion, the flue gas in combination with comfortable, and sulfuric acid produced in the condensation and corrosion of the metal in the metal surface below the dew point. 4, stress corrosion: refers to brittle cracking occurs under tensile stress while the action of the metal in the particular corrosive medium and a certain level. Second, the water-side corrosion comprising: 1, corrosion free carbon dioxide: hydrogen water acidic substance depolarization caused by corrosion. Corrosion Methods: water equipment to try to remove the CO2 and carbohydrates. 2, under deposit corrosion: the metal surface when you boiler slag or scale adhesion, severe corrosion can occur beneath it, referred to precipitate corrosion. Corrosion Method: The pH of the water in the apparatus is maintained at between 9 and 11, the metal surface of the boiler protection film is stable, does not corrode. 3, soda corrosion: the metal corrosion is a chemical vapor oxidation of iron occurs. The method of anti-corrosion: Depression evaporating section smaller inclination angle, ensure the normal circulation, for higher superheat temperature superheater, heat should be used, good corrosion resistance and the like of steel pipe. 4, DO corrosion: In the soda system, metal corrosion of the steel is prone to corrosion by dissolved oxygen. Corrosion: Water favor oxygen, increase the flow rate of water, to avoid the accumulation of oxygen in the respective area, so that uniform contact of oxygen with the metal wall to form a more uniform corrosion. Boiler is very special operating environment, temperature and pressure and corrosive substances can cause equipment corrosion conditions occur, for which we have to take the right precautions to avoid future corrosion occurs during use.
High-Pressure Boiler Definition. High-pressure boilers will heat steam above 15 psi and water at pressures that exceed 160 psig. Temperatures in high-pressure boilers will exceed 250 degrees F. Because of the elevated pressure at which these boilers operate, they need to be monitored to ensure safety at all times.Online chat
Effective Boiler-Level Control. By most manufacturers' standards, high-quality steam is 99.5-percent dry saturated steam. For a boiler to provide an appropriate amount of such steam safely, efficiently, and at the correct pressure, the amount of water inside of the boiler must be carefully controlled.Online chat
As the water supply comes from the mains, at mains pressure, your water will be of a high pressure and suitable for a large majority of high pressure taps provided you have a fairly good combi boiler. Pressures can vary from boiler to boiler, but the typical pressure expectation from a combi-boiler is somewhere between 1 and 2 Bar.Online chat
The bottom blow down is done at least daily (more often depending on boiler water conditions) to blow out scale and mud from the bottom of the boiler.
