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.
After the gas industrial fired fire tube hot water boiler price hot water boiler vaporization emergency 1. Vaporization handler circulating pump stops abnormally pump failure caused by: ① blower stops running immediately. ② immediately open the door, take measures to pressure the fire, lift the chute gate, cutting off the supply of coal grate. ③ In the case of boiler pressure not greater than 0.6MPa (600KPa), the exhaust valve to follow, only a sharp rise in pressure in the boiler deflated, used only relief exceeds 0.9MPa, and the exhaust process to be carried out slowly, prevention boiler due to loss of pressure and more violently again vaporized. ④ close the boiler water, water main gas valve. ⑤ open stop valve recirculation line, to ensure that the water supply pipe velocity convection heating surface (economizer) to prevent re-vaporization of the economizer. ⑥ The operation of the above operation, at the same time to pay the boiler to reduce the boiler water temperature and the furnace pressure. ⑦ After the boiler pressure is normal, i.e., opening the standby circulating pump, into the normal combustion. 2. Treatment failure or sudden loss of power boiler vaporization of power: ① immediately open the door, lift the coal chute slide gate to take pressure fire measures to reduce the oven temperature. ② Grate with the fastest speed in order in the shortest time to fire onto the slag tap. ③ the degree of treatment in the first case. Once a short time can not supply heating network system, antifreeze should take emergency measures. 3. Due to excessive heat boiler boiler vaporization process: ① the immediate closure of the drum, induced draft fan. ② immediately open the door, take measures to pressure the fire, lift the supply of coal chute slide gate, off of coal, while the grate into fast gear. ③ In the case confirmed the presence of water, the boiler can supply water to the boiler body, boiler out of the water while closing the main valve. ④ Open line stop valve recirculation pump to ensure water velocity convection heating surface of the pipe, to prevent the economizer again vaporized. ⑤ Open circulating pump with jog mode, jog each time less than 30 seconds, again less than one minute jog interval. Jog purpose is to reduce the boiler water temperature, while preventing a large amount of steam into the pipeline system. ⑥ back into place after the safety valve, circulating pump running, and then the normal burning stove. 4. Water boiler system run vaporization process due to water loss, loss of pressure caused by: ① immediately closed drum, induced draft fan. ② out of the water while closing the main valve and the boiler circulating pump. ③ take the same measures to cool the furnace tube described above. ④ Open stop valve recirculation line. ⑤ rely exhaust valve until the safety valve back into place. ⑥ until the boiler water temperature drops below 50 ℃, when the temperature of the furnace temperature less number 200 ℃, again within the boiler feed water, water course to be carried out slowly, to prevent harm to the boiler when the temperature is too large. ⑦ After processing leakage fault, the system time to the replenishment, and out of the water boiler always open the valve, and the circulating pump, and then normal combustion.
Shunde main business of special sea oil production and processing, etc., in the course of special oil refining, a large amount of steam required for oil and gas extraction, distillation and extraction technology and other aspects, therefore, the boiler is supplied special sea oil processing technology company Shunde indispensable less equipment. As environmental policy progresses, the chemical industry as more polluting industries are highly valued the various departments of quality supervision, sea Shunde companies to follow the development of the State Environmental Protection pace, choose clean the boiler industry-leading fast Boiler cooperation with the parties by quickly assess the specific needs on-site estimates and sea Shunde, to provide a SZS series of 25 tons of steam water tube steam boiler (SZS25-2.0-YQ).
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.Free Chat
