Recently, Pingliang City, issued the latest "Pingliang City to win the Battle of Blue Sky 2019 annual implementation plan," we can see, Pingliang City, determination and efforts for the improvement of the atmospheric environment. Details are as follows.

First, in an orderly clean winter heating. Seriously implement the "Pingliang City winter heating clean overall plan (2018-2021 years)," according to an alternative clean, affordable, affordable residents principle, using a combination of all types of cleaning of heating, substitution of coal for heating. Full implementation of national, provincial and clean energy heating prices on northern policy support, accelerate the clean heating work.

Second, continue to promote the comprehensive improvement of coal-fired boilers. On the area of ​​coal-fired boilers comprehensive investigation, according to "a furnace of a policy" requirements, to promote the comprehensive improvement of precision work. Increase efforts to eliminate small coal-fired boilers, the county level and above urban area per hour and 10 tons of steam coal-fired boilers and pantry oven, stove operating, grain storage and drying equipment, coal-fired facilities out rate of 60%, principles the 35 tons of steam per hour, no new coal-fired boilers, in principle, to the rest of 10 tons of steam per hour, a new coal-fired boilers. Dispersing the concentrated coal-fired boiler heating pipe network grid should be eliminated, the coal-fired boilers and gas dispersion pipe network should be implemented under the premise of coal to gas in the implementation of the air supply and gas supply; central heating and no gas pipeline network coverage area scattered coal-fired boilers, energy saving and environmental protection in line with national requirements, compliance governance reform can be implemented smoke, does not meet the requirements, it should be replaced by electricity, alcohol-based fuels and other clean energy; industrial Park (zone) press the "one District one heat source "requirements, an orderly phase-out of demolition and decentralized heating boilers; in remote rural areas, affected by economic and other conditions can not be eliminated or temporarily restrict use clean energy alternative to coal-fired boilers can be taken to use clean coal and other ways to achieve the flue gas discharge standards.

In the process fuel gas boiler oven, furnace pressure, gas temperature, oven time should be adjusted according to actual requirements, to ensure the quality oven. In addition to these, also into the hole door needs to close both sides of the boiler, and the boiler water into the water softener via the water supply system.

Features boiler during operation of the drum 1. The composition of operating pressures and gas turbine combined cycle diesel industrial steam boilers price blowdown waste heat boiler has two or three drum, each drum minutes, run at different pressures, such as boilers combination of three steam drum, the drum has a pressure of a pressure drum, a low-pressure drum. In addition to the low pressure steam low pressure steam into the drum is not generated and the steam turbine into the deaerator, the high pressure steam supply to the steam drum Du machine. Qian any type of boiler, such as the presence or steam separator drum level fault, will produce serious chemical injury; for multi-component waste heat boiler drum, Q will be more serious. Further, in order to save water and energy transfer, sewage discharge way from the upper drum to the lower drum, and chemical changes affect the other drum in a steam drum. 2. Only water wall tube number 1 is set in the conventional exhaust heat recovery boiler waterwall tubes, the tubes can absorb heat due to the surrounding child, the cold side of the hot-side heat conditions conventional boiler waterwall tubes absent. On the other hand the flue gas flow, boiler, different heat flux and heat flux at the last row of finned tube of the first row at the finned tube, the difference was greater at startup. Typically, the first row of fins flue gas stream corresponds to the riser pipe, finned tube corresponds to the last row of the downcomer. However, the temperature rise in the boiler startup phase, as yet supplied to the steam turbine, the flue gas flow tuna rearmost tube sheet may be reversed, so that it corresponds to the initial rise in concentration of the chemical composition should be low, which allows the wall the resulting precipitate was minimal. 3. In addition to the waste heat boiler of the gas turbine combined cycle, oxygen is an important part of the low-pressure steam drum. Typically, low pressure steam into the low pressure steam generated by the drum deaerator feed water and makeup water to provide resources, as alternate start boiler is not provided, so that if the outlet steam pressure boiler system deaerator and the deaerator at start when open to the atmosphere, stop shutdown, the water tank to absorb oxygen, oxygen dissolved in water combined cycle heat recovery boiler causes pitting and fatigue corrosion. 4. The waste heat boiler because the DC current is no waste heat boiler drum, economizer nor evaporator superheater, when water flows through the tube bundle, the position of the interface is dependent on water vapor partial pressure of the water flow and heat absorption. 5. Run peaking gas turbine waste heat boiler can be designed to start and stop frequently, with a peak load operation, the situation in the future, peak load operation with frequent starts and stops often appear. But many ask the waste heat boiler with frequent stops the unit is related to the waste heat boiler difficult to adapt to frequent starts and stops with the state of the peak-load operation, the waste heat boiler operating status will cause a large thermal stress and chemical corrosion. These are the boiler equipment produced in the course of their work which reaction: inside equipment parts need to pay more attention, are carefully marked out.
