standing hot water boiler China
Fault boiler long, short sootblower: sootblowers is essential for an important part of a boiler, its role is to purge the ash heating surface, heating surface remains clean, in order to improve the heat transfer effect, to ensure that the thermal efficiency of the boiler, to prevent the heating surface of the coking device. It points both long and short, then, the next will come to tell you what it's common faults and solutions: 1, long soot blower common failure symptoms: (1) failed to start and soot blower soot blower is not from the back. (2) leakage into the boiler soot blowers. (3) at the inner tube was sealed severely sootblower steam leakage, water leakage poppet valve lifting rod. (4) steam inlet flange sootblower steam leakage. Analysis: (1) the control part of the fault. (2) motor failure. (3) firing barrel deformation or Jam. (4) damage to the valve body and the valve seat surface binding. (4) sootblower boiler tubes, damage to the poppet valve packing. (5) an inlet flange sootblower graphite spiral wound gasket failure damaged. Treatment: (1) an electric contact personnel check and control system of the expansion power supply line La on whether the device. (2) an outer barrel furnace boiler sootblower bending portion rapidly burn local manual hand-crank or exit from the barrel as the slide bearing support readjust and corrected barrel, the barrel as serious deformation should be replaced with new of. (3) isolated after the individual valve lift system maintenance, disassembly of the poppet valve and the valve seat and the valve body is polished with a special tool maintenance, such as severe damage to the valve seat or the valve body and replaced. (4) the inner tube packing isolated after replacement of individual systems, note moderate tightening gland studs. (5) to replace the gasket flange. Preventive measures: (1) strict inspection process. (2) to strengthen the inspection, to detect problems in time.
Food issues when buying gas steam boiler plant to be considered a problem which foods to buy gas steam boiler plant to consider what? For many food plants are required to use gas steam boiler, the boiler before the purchase is the need for a detailed understanding of the factors affecting the price of gas steam boiler. Many factors affect the price of gas boiler. Specifically, the following areas: 1, boiler capacity. As one ton, two tons, four tons, 10 tons, 20 tons of different sizes, such as the price difference NATURAL furnace. The price of one ton of pressure 1.25MPa WNS1-1.25-YQ type gas boiler is about 120,000. 2, boiler models. Common types of oil-fired boiler WNS and SZS type of two types. 3, the parameters are parameters affecting fuel boiler rated evaporation, rated steam pressure, the rated steam temperature, water temperature, rated thermal power, rated outlet pressure, water temperature, return water temperature, gas consumption, power consumption and design of the fuel. Prices vary.
Low nitrogen boiler technology made a major breakthrough, however gratifying that through the unremitting efforts of domestic boiler companies, China's low-NOx combustion technology gradually into the world advanced list, catch up with a lot of foreign advanced technology.
Well, atmospheric pressure standing hot water boiler china and hot water boiler What is the difference? This is what we are concerned about. High-pressure hot water boiler heating system susceptible to stress, there is a risk of explosion. Atmospheric hot water boiler heating system was not added pressure, and the atmosphere is always the same, so there is no risk of explosion.
