CE gas-fired hot water boiler wall hung gas boiler

Tai Chi, Jiaozuo City, Jiaozuo City Sports Center is one of important sports infrastructure, a total area of 11.73 hectares, held several international events. With strict management in Henan Province for air emissions of pollutants, Jiaozuo City, also launched the governance of coal-fired boilers, thermal power and other equipment. Jiaozuo Sports Center actively cooperate with municipal workers, took the lead from coal to gas activities, the serious pollution of the original extent of coal-fired boilers to replace gas boilers. Gas boiler cleaning binding understanding of the market, to achieve cooperation with the finalization fast boiler by providing a fast side 2.8MW integrally condensing gas ce-fired hot water boiler wall hung boiler (WNS2.8-1.0 / 95/70-YQ), it is used to Sports Center provides heating and hot water.

How how electric steam boiler maintenance electric steam boiler maintenance 1, boiler maintenance, must be cut off and must relief. 2, the burner every two months to be removed from the boiler, carefully remove foreign bodies such as dust and soot. Photocell light-receiving surface wipe once a month, fuel filter should always be kept clean and filtering capabilities; carefully clean the filter in the pump, do not break the seal. Oil-burner not idle, so as not to damage the pump. 3, the water level gauge should always be kept clean, rinse the purge valve is opened, the water level in order to ensure a clear day. 4, pulling the safety valve once a day, to prevent rusting failure. 5, electric steam boilers stop running long time, turn off the power, and do maintenance work: (1), dry maintenance, shutdown after the release came out water, dirt clean the furnace, with a slow fire the burner drying pot (burning time not too long, to avoid damage to the boiler), then all of the drained gas boiler, all pipe valve closed, checked every three months. (2), wet maintenance for a period not exceeding one month shutdown of the boiler, furnace shutdown after water release, discharge and clean fill with water, cut off the power, close the valve.

First, the design principle WNS type boiler and a gas main features. 1, WNS type boiler design principle and structure: WNS is a wet back boiler shell three-pass horizontal fire tube boiler, this structure uses three return, the oil mixed with air or gas well through the atomizing burner, in the complete combustion furnace in a corrugated, folded from the rear chamber into the first tobacco smoke return tube, to a second smoke box to the front return pipe tobacco, tobacco after entering the last tank, is discharged from the chimney. It has strong adaptability to different fuels, combustion of heavy oil, light oil, natural gas, city gas. Low power consumption, load regulation ratio. Boiler automatic control, adaptability of the burner. Using imported burner, reliable performance, high degree of automation. 2, the main features of the WNS type boiler: High (1) combustion efficiency, safe and stable, space-saving, fuel-saving, low investment costs to buy fuel; (2) full-pull edge butt welds, boiler safety, long life, maintenance costs low. (3) there is arranged a tail flue gas condensation recovery, can effectively control the exhaust gas temperature, high thermal efficiency of the boiler; (4) with automatic burner, water continuous electric adjustment, high combustion efficiency. (5) The quick configuration, the entire boiler design on the steel strong base, easy installation and transportation, saving the boiler room floor space area. Two, SZS type gas boiler structure and characteristics: SZS longitudinal type double drum "D" type arrangement quick water boiler. It consists of upper and lower drum, membrane wall, the convection tubes, condensers, and economizer, disposed in the front wall of the burner, the combustion of the fuel in the furnace, flue gas convection bank, an economizer and a condenser into the chimney. The main features are: (1) The double boiler drum "D" type arrangement, compact, small footprint, good flame fullness. (2) the boiler supporting mode can be free to expand upwards. (3) furnace wall and membrane in all convection pass wall structure, good sealing and maintenance work and reduce the use of refractory bricks. (4) The quick boiler structure can effectively shorten the installation cycle. (5) arranged economizer tail, can effectively reduce the exhaust gas temperature, high thermal efficiency of the boiler. (6) The whole boiler steel seat strong base, easy transportation and installation. (7) having a heating surface surplus, soda and a sufficiently large space to ensure stable boiler parameters. (8) with automatic burner, combustion efficiency and an ignition control program and overpressure, flame protection. Third, the application type WNS and SZS boiler used in Example 15 t: In addition to evaporation, working pressure, as the fuel is used, the two contrast, WNS size slightly smaller type gas boiler, small footprint, from a cost perspective, slightly lower than SZS type gas boiler, the thermal efficiency of the boiler is almost the same, but their difference only lies between 1 t -20 t tonnage, the conventional WNS type gas boiler, and SZS-type gas-fired boiler more than 4 tons -60 tons, even to 90 tons.

Boiler water in what is related to a question of hard water and gas boilers: issues related to the boiler, in fact, there are many, but, that is what we all need to know and grasp, because it is in the boiler knowledge system, if not very good grasp, then, it will affect the learning process, but also will affect the use of the boiler, so we should take seriously and carry on. So, without further ado, immediately to proceed with it, its details are as follows. 1. boiler water, how it is called hard water? Boiler water, which generally contain impurities, mainly those of calcium and magnesium salts and the like. If its hardness is more than 8 degrees, which was called hard water, and then use it easily form hard scale in a boiler, thus, increases the energy consumption of the boiler. Therefore, it should be resolved, and to avoid this problem. 21 000 kcal boiler is equal to how many tons? In addition, the boiler heating pipes froze, how to solve? 1,000,000 kcal boiler, which is equivalent to 1.7 tons of boiler, because 600,000 kcal equal to 1 ton, therefore, will have this conclusion. The boiler heating pipes froze, its solutions, mainly in the following several, it is as follows: a measure: low temperature boiler operation, by gradually increasing its temperature to thaw naturally. Measures II: the use of fire, welding, or the use of liquefied petroleum gas were roasted. Three measures: the use of electric heating or hot water pouring to thaw.
