boiler manhole specification

Ukraine industrial construction quality, customer Ukraine's current visit to our company is very interested in industrial steam boiler manhole specifications. Our technical staff will fast one side condensing gas steam boilers, steam pipes condensing gas boilers and other star products, from performance to the advantage of his right to the customer. Natural gas is clean, easy to use and other advantages, is to use one of Ukraine accounted for a large amount of the type of energy. Fast boiler since its inception in 1998, with great concentration R & D and manufacturing of gas clean fuel boiler, has a very extensive industry experience, and to respond positively to the pace of global environmental development for the market launch of the gas boiler is not only the thermal efficiency is very high (up to more than 108%), emissions of harmful substances is very low (less than 18 nitroxides mg / m3).

Burner gas boiler manhole specification suddenly does not run, why not?

Burner is the most important gas boiler auxiliary equipment, mainly for ignition and combustion of the fuel, a burner not only allows good combustion of fuel, but also to achieve even lower than the oxynitride 80 30 mg matter (NOx) emissions for nitrogen oxides demanding cities (Beijing, Xi'an, Zhengzhou and other places) is very friendly. It can be said burner operating normally or not directly affect the operating results of the gas boiler.

Boiler leakage of pharmaceutical and correct operation of the boiler manhole specification leakage causes and correct operation method pharmaceutical methods commonly used in the pharmaceutical boiler is a steam boiler, in the course of its use because of improper boiler operation, there may be some or that kind of problem where flue boiler corrosion caused by water leakage problem is one of them. The reason for this phenomenon a. Boiler feedwater oxygen scavenging process is not performed, resulting in chemical oxygen should, boiler, or other ingredients of the metal parts, boiler corrosion occurs, not in time for a long time, causing the boiler water leakage. b. routine improper operation, shutdown did not close when the water supply valve or the steam valve main pipe, air into the furnace, and again use the boost, the incoming oxygen is not timely removed, so that in a hot and humid environment caused by oxygen long-term corrosion perforation of the smoke pipe. Precautions: in strict accordance with standard operating a steam oven in accordance with operation of the boiler feedwater standards GB1576-2008 oxygen, reduce the oxygen content, avoid the presence of oxygen, chemical corrosion. b. When shutdown, when the boiler is in the normal high water level shutdown and normal pressure, and then close the inlet valve and the main valve, to prevent intrusion of outside air oven. c. boiler room to keep dry, clean, ventilated, while the process of personnel to operate the fireman to be precise, compliant. d. strengthen valve maintenance, maintaining rigor. In short, there are many reasons causing leakage of pharmaceutical boiler, but if the mistake is due to improper operation caused by the boiler, it should be noted in particular the normative operation, prudence, as far as possible preventive measures.

In the denitration process of the boiler manhole specification, the boiler heating liquid water, the water temperature rises, when it reaches the boiling point, although the heat is being added, the temperature of the water will not be increased, remained at the boiling point, add heat to the water only into steam, i.e. from liquid into gas. This does not change the temperature of the substance to cause a change of state of heat (also known as a phase change) is referred to as latent heat. 1Kg liquid becomes completely saturated with the heat absorbed by steam at a temperature, known as the latent heat of vaporization at this temperature, represented by the symbol r, in units of kJ / kg.
