So, how to choose a suitable gas boilers do?

A boiler working pressure

March 11, we learned from the Harbin municipal government: Harbin win the 2019 New Blue Sky Battle embodiments released this year, Harbin will be coal-fired pollution control, pollution discharge standards, high Vehicle emission control, comprehensive improvement of urban and rural non-point source, and prohibiting straw utilization as the main direction, precise Shi policy. Strive to the end, so that the sulfur dioxide, nitrogen oxide emissions are reduced by more than 17.6% in 2015 and 20%; concentration of PM2.5 decreased to 52 micrograms / cubic meter or so, and strive to 50 micrograms / cubic meter or less; and more severe reduce the number of pollution days to 21 days or less.

After the proposed scheme, Harbin bulk coal strengthen management and control, strengthening coal quality testing, to improve the sampling frequency. This year will develop clean heating embodiment, the priority development of the city urban central heating; central heating covered areas being difficult to accelerate the implementation of natural gas heating and electric heating, and other distributed clean heating. Unit embodiment "coal to clean energy" should be synchronized removal of coal-fired boiler, gas boiler need replacement after low NOx combustion technology, clean heating rate of 60% or more. City buses, taxis or car clean energy proportion of new energy and strive to reach 94% and 80%. Promote the use of gas vehicles to achieve the national emission standards for six. Six to stop selling below the country's gasoline and diesel. Establish responsibility dust control system, built-up areas prohibit the construction site mixing of concrete, mortar and use of bagged cement 9 city and county (city). Under the premise of protecting people's livelihood, heating boilers should be relatively conducive weather conditions during the pollutant dispersion from the oven, in the same area by different heating boiler early in the evening three periods of peak load shifting from the furnace.

Henan fast boiler supervisory inspection-free gas steam boiler steam boiler energy-saving programs in many applications, will have this situation: boiler room with steam from the steam boiler point is very far away, so in the steam process requires large amounts of steam through piping connected to the steam boiler steam points. What is the extensive use of energy saving steam line losses it? 1, the steam pipe length will affect the supply time of steam boiler steam after the steam generation, and not directly to the steam point, but to continue heating the steam produced in the steam pipe, so would extend the steam boiler for the steam time . 2, during transport of the steam will be present in the steam pipe when the heat loss of the steam supply, although the pipeline itself for a certain length of insulation material, but the heat losses still occur. 3, the pipe run, run, leak, drip is generated after a long time, it generates heat loss capacity using steam piping run, run, leak, drip phenomena, resulting in the loss of steam. 4, and the influence of steam vapor in the dry pipeline quality during delivery resulting in heat loss due to the decrease in temperature of the steam, condensation and even affecting the quality and the dryness of the steam. 5, the unused tube steam loss occurs unused steam tube steam can not be used, resulting in loss. In summary, the use of the longer steam line, will produce more steam loss. Especially for frequent starts and stops of the boiler, the greater the amount of loss generated. Therefore, the lower the steam boiler from the point of steam, the steam produced smaller loss. However, due to space limitations and the national regulatory provisions for steam boilers, conventional steam boiler can not be placed directly next to the steam point. State regulations conventional steam boiler must establish a separate boiler room, boiler room and a variety of explosion-proof requirements. Henan fast boiler steam boiler is a no supervisory inspection of steam boilers, due to the water capacity of only 27L, very safe, so I do not belong to the national regulatory scope. Henan fast boiler steam boiler small size, light weight, can be placed directly implemented next point real-time for the steam stripping.

Henan run Q & Gas Boilers (b) 1. Internal gas boiler drum Henan mainly those devices and how they effect the arrangement position A:?? Henan gas boilers with capacities of different parameters, it is not exactly the drum inside the device - like, now at high pressure and ultra-high pressure boilers drum example, describes internal devices, their arrangement and a major role. Along the length of the drum is mounted at both sides of a plurality of cyclones, each cyclone barrel top is arranged a louver (wave plate) separators, their primary role is to rise by the tube into a mixture of soda and water vapor will be the initial separation. In the upper steam drum, steam cleaning horizontal mounting plate, on which the cleaning water supply layer, when the steam passes through the water layer, put dissolved or carried vapor partial turn salt was dissolved in water, to reduce the steam salt. Near the top of the drum is provided with a perforated plate, a uniform flow in the ascending vapor drum, and the water vapor is further separated. About 150mm with the drum center line of the discharge pipe opening accident; continuous blowdown piping is provided at approximately 200mm port under normal water line, and then disposed below the dosing tube. Also installed at the entrance of the downcomer cross blade. To prevent a drop generating swirling nozzle causing drop tube bucket with steam. 2. Continuous outfall mouth Henan gas boilers are generally installed where? Why? How much sewage rate? A: Top nozzle Henan continuous gas boiler 200 is generally mounted on a drum at the lower 300mm normal water level (i.e., "0"). Since the pot of water evaporation continuously gradually concentrated in the vicinity of the surface of the water with the highest salt concentrations. Therefore, continuous blowdown piping port Henan gas boiler should be installed in the region of the maximum boiler water concentration to high concentration continuously withdrawing boiler water, supplemented with clean water supply, thereby improving the quality of boiler water. Henan gas boiler blowdown rate is generally about 1% of the amount of evaporation. 3. What pot of water treatment dosing in Henan gas boiler drum sense Answer: the pot to prevent the fouling, if simply to remove the water contained in the outer boiler feed water hardness, needed more equipment will greatly increase investment; and plus? cauldron blowdown, heat loss not only increase the working medium, can not be eliminated pot residue water hardness. Thus, in addition to using external boiler water treatment, but also on the water in the boiler pan dosing process, remove the pot residue water hardness, to prevent boiler scaling. The method of addition of phosphate which is in the pot of water, so that calcium and magnesium ions and phosphate ions bound water pot, Rong generating hard water precipitation sludge, sewage regularly excluded, so to maintain a certain boiler water phosphate, neither fouling and corrosion, but also to ensure the quality of steam. 4. What Henan gas boiler regularly sewage outfall aim is installed in the mouth where A:?? Because Henan pot of water gas boilers containing rust and dosing process water precipitated the formation of slag and other impurities deposited on the bottom of the water circuit, regular sewage the purpose of the water is periodically discharging slag and other impurities precipitate, increasing the pan of water quality. Periodically outfall generally located in the lower header, or concentrated water wall lower portion of the downcomer.
