The method of adjusting the temperature of the superheated steam heating stove have? The method of adjusting the temperature of the superheated steam heating stove have? DC boiler steam temperature is mainly adjusted by adjusting the quantity of fuel to water. In actual operation, because the efficiency of boiler feed water and fuel heat enthalpy (depends on the water temperature) and the like will change, so the actual boiler operation to ensure the water-fuel ratio of the exact value is not easy. Coal-fired furnace will fluctuate because of the amount of coal and the amount of fuel due to the steam temperature. So, except DC boiler fuel to water ratio as the coarse adjustment means, but also must be used as a method of spray desuperheater means of fine-tuning adjustment. There is also some boiler flue gas recirculation, dampers and methods of the swing center of the flame as an auxiliary adjusting device.

The picture shows the fast boiler processing plant located in the plain areas, plus catch up period is for a residential area of ​​Beijing for the production of low concentration of nitrogen product water tube boiler heating in winter, as scheduled in 2018 to ensure that heating at the same time, to meet the 20 mg / m require extremely low emissions of nitrogen oxides, Beijing air emission standards applicable to other regions 30 mg / cubic meter.

Boiler manufacturers tell you how maintenance of the gas boiler? As we all know, gas boiler needs regular maintenance, fast boiler factory in Henan home introduction, maintenance must make adequate preparations when maintenance work is required to measure the device is working properly with the naked eye before the whole maintenance, especially in the combustion when the chamber for maintenance or repair, shall professionals. In daily life we ​​should also strengthen the monitoring of gas boilers, the following fast boiler factory in Henan home tells you how the gas boiler for maintenance? 1. According Henan fast Boiler Manufacturers factory stock company, maintenance when cleaning the pump inlet filter and the first oil filter screen, check the pump packing like open manhole, hand hole cleaning the boiler, the boiler internal structure inspection dirt and corrosion conditions, to determine the treatment period and determine the need for regeneration chemical cleaning; washing water level gauge, three-way stopcock, etc., to check for leakage situation. 2. In addition, attention should also be part of the control box and check whether a circuit is loose, if loose should be timely corrected to professionals, Henan fast boiler manufacturers suggest that the most important thing is fouling cleaning, check all valves are intact, and comprehensive cleaning operations, the rotation of the mechanical parts once the lubricating oil is added or oil change. 3. Open the next best fire smoke box front door, and check the gasket soot corroded, to determine whether to replace and clean. Henan fast boiler manufacturer of professional maintenance staff Tip: When the smoke box before opening, the burner should be detailed examination of the burner is burned to update. 4. Finally, you should check for corrosion and other water and sewage pipes every year, which is essential for extending the overall life of the product, leading fast boiler factory in Henan Tip: To focus on checking the insulation of electrical, electronics, circuit, cable also check the electric meter box in each instrument, buttons, gauge the correctness, after the completion of the preliminary examination is also required to review the work of 1-2 times, and strive to make equipment running smoothly. Finally, there is a gas boiler maintenance frequency of the problem, the main factor maintenance frequency has a frequency of use and the space environment, especially the space environment changed greatly or when the space environment more hostile, it should be an appropriate increase in the maintenance and the number of maintenance and avoid aging of components, affect the overall service life. Henan fast boiler manufacturers IMPORTANT home, boiler maintenance must be operated by professionals on behalf of, non-standardized operations to avoid personal cause subsequent problems.

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 town water boiler with ce. 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.
