Gas heating flow proses pc boiler power plants Maintenance brief (two) to share with you a small series of measures dry gas heating boiler maintenance, then share with you another maintenance measures that the maintenance of the wet method. Three wet maintenance method: (1) After heating boiler shutdown, we must first produced during the operation dirt clearing is completed, in the process should have a tubing connections with the outside world were cut block. (2) the internal heating boiler filled with demineralized water, avoid incorporation of air, in the process, should be carefully monitored to ensure no leakage of boiler. (3) filled with the gas heating boiler, an alkaline solution, the surface of the metal protective layer produced alkaline, boiler avoid corrosion phenomena. The above are some commonly used method of wet maintenance of boilers, of course, you may also have better ways, who will need to be different debugging, and choose a more appropriate and reasonable ways and means depending on the situation. In short, boiler maintenance shutdown of the boiler is the process of using a more important part to ensure that the boiler can always be safe and stable up and running.

Condensate recovery flow proses pc boiler power plant of Embodiment 1, how the recovery boiler steam condensate recovery system recovering exhaust system high-temperature condensed water, the condensed water can maximize the use of heat, water conservation, fuel economy. Condensate recovery system can be divided into open and closed recovery system recovery system. Recovery system is open to a condensate recovery tank to the boiler, the condensed water recovery and utilization in the process, one end of the recovery pipe is open to the atmosphere, i.e., the condensed water collection tank is open to the atmosphere. When the lower pressure of the condensed water, can not be reached by the pressure from recycling properties, high temperature condensed water pump pressure-feeding. The advantage of this system is that the device is simple, easy to operate, a small initial investment; however, a large area of ​​the system, resulting in low economic efficiency, larger environmental pollution, and since the condensed water is directly in contact with the atmosphere, dissolved oxygen concentration in the condensed water improved, easy to produce equipment corrosion. This system is suitable for small vapor supply systems, a small amount of condensate, small amounts of secondary steam system. When using this system should minimize emissions of secondary steam. Condensate recovery system is a closed tank and all piping are set at constant pressure, the system is closed. Condensate system has most of the energy recovery through a certain recovery device directly to the boiler, the condensed water recovery temperature loss in the cooling portion of the pipe network only, since closed, quality assurance, the water reduces the cost of recovery into the boiler . The advantage is economic good condensate recovery, long working life of the equipment, but the system is relatively large initial investment, operation inconvenient. 2. Select recovery methods for different condensate reconstruction project, which way the recovery and recycling equipment selection, is whether the project can achieve the purpose of investment crucial step. First, we must accurately grasp the condensed water condensate recovery system, if the condensed water is not calculated correctly, will make the condensate pipe diameter selected too large or too small. Second, to properly control the pressure and temperature of the condensed water, which embodiment uses the recovery system, which device, how to arrange the pipe network, the condensate temperature and pressure are related. Third, the trap condensate recovery system is selected to be noted that the content, wrong trap selection, will affect the pressure and temperature at which condensation water use, also affect the normal operation of the recovery system. Recovery efficiency is not as high as possible in the system selection, but also consider economic issues, that is considered waste heat utilization efficiency, we must also consider the initial investment. Due to the high efficiency of closed recovery system, less environmental pollution, are often preferred.

Recently, Shandong Province, issued a "thermal power plant air pollutant emission standards (DB37 / 664-2019 instead of DB37 / 664-2013)". Standards will be implemented on September 7, 2019.

First, the standard applicable to the use of a single output 65t / h or more layers in addition to coal-fired burner, furnace stoker boiler or steam generator; single output 65t / h or more oil, gas, or steam generation boiler; single output 65t / h or more power using steam boilers other fuels; pulverized coal fired boilers of various capacities; various capacities gas turbine. Gas turbine integrated gasification combined cycle power generation is performed in this standard gas turbine exhaust gas as a fuel limit.

Environmental Impact Assessment II. This standard is applicable to the existing project management of emissions of air pollutants, as well as the above-mentioned new construction, renovation, expansion projects, environmental protection facilities design, environmental protection facilities acceptance, pollution permits and air pollutants after putting into operation emissions management.

With sugarcane, the stalks are basically pulverized, and water and lime are added to produce a juice. The juice is boiled until the sugar crystallizes. The crystals are run through a centrifuge, which separates the syrup. In the final stages, the sugar goes through the refining process, which involves washing, filtration and other purification methods to produce pure, white sugar crystals. Bagasse can be used to fuel the flow proses pc boiler power plant.
