When using electric import from china cfb power plant boilers need to pay attention to what issues? Use electric boiler problems that need attention. Before operating the first electric boiler should carefully read the product manual, in strict accordance with the instructions, so as to correctly understand and use electric boilers, it will not affect the use of operational errors. Second, the need to carefully check before starting electric boiler water source, and the power supply voltage, to ensure that there is no abnormality, and then the valve is opened, the water fills the conduit, the electric boiler into operation time. Third, when the electric boiler failure when maintenance needs to be re-checked after the power is turned off, but also to increase security. Fourth, to maintain electric boiler clean, damp work to do waterproof pump motor, electric control boxes and other parts. If conditions permit, can be prepared in a small boiler room. Also to be regularly fittings and spare pipeline pumps, pipe inspection, and take all security work.
Pharmaceutical import from china cfb power plant boiler full of water Accident pharmaceutical boiler when selected, mostly steam boilers based, then, in the course of its references in this or that problem will be inevitable, the boiler is full of water in which the accident one of you in the face of such a phenomenon should be how to solve it? the reason pharmaceutical boiler filled with water accidents (1) water gauge failure, can not judge normal water level in the boiler, causing interference to determine the operator. (2) If the water pressure of the boiler sudden increase in water speed will accelerate, and should the inspection staff is not recognizing this phenomenon, it is likely to cause accidents occur boiler full of water. Process boiler operation (3), or it may exist fireman who neglects his duty, over-reliance on boiler feedwater automatic control system, once the system failure, it is very likely to cause full of water accidents. Measures Pharmaceutical boiler filled with water accidents (1) to detect the water table at any time, to ensure the normal operation and its sensitivity to its normal feedback boiler water level situation, full of water to avoid the phenomenon. (2) If the boiler full of water and the accident has occurred, should be made to deal with the emergency shutdown, stop the boiler feed water, turn on the water quickly, hydrophobic, when the boiler water level to be back to normal, the relevant component inspection to ensure the normal time, restore the normal operation of the boiler . (3) In addition, the boiler full of water accidents in part due to operational reasons the boiler itself, the other part also and operations fireman who has a direct relationship, therefore, on a regular basis to the relevant personnel training, the development of relevant work rules, ensure operational co reasonable regulation. Of course, the cause of the accident boiler full of water and there are many specific treatment to be based on the actual situation, as a preventive measure to ensure the safe and efficient operation of the boiler, especially pharmaceutical institutions like the slightest mistake is likely resulting in unnecessary human and material losses.
Gas import from china cfb power plant boiler heat loss through the combustion of fuel gas boiler, will release some heat, automatic gas boiler which will supply part of the heat user, some will be recycled and part is inadvertently wasted. So these are wasted heat lost through the ways in which it (1) Automatic gas boiler flue gas heat loss:? Flue gas exhaust gas boiler part of the heat into the atmosphere, causing the heat losses of the boiler, it is the boiler heat loss Dazhong biggest one. The main factors influencing the heat loss is higher exhaust gas temperature and the amount of smoke exhaust gas temperature, the greater the amount of smoke, the greater the heat loss. Low exhaust gas temperature depends mainly on the number and operating conditions of the heating surface; the amount depends on how much leakage exhaust case and the furnace excess air, flue. (2) heat loss incomplete combustion gas: a part of the unburned combustible gas is discharged with the flue gas to heat loss caused by heat in the flue gas. The main factors affecting the incomplete combustion gas heat loss is the excess air and furnace structure. Excess air coefficient is too small, uneven air is mixed with fuel, easy to generate carbon monoxide and other combustible gases; excess air coefficient is too large, the furnace temperature is lowered, the combustible gas is not easy ignition and combustion. Furnace volume is too small, combustible gases in the furnace too late to enter the combustion flue gases caused by incomplete combustion heat loss. (3) heat loss: the furnace heat loss, frameworks, pipes, door opening caused by heat dissipation to the surroundings. Size depends on the heat loss factors of the size of the surface area of the furnace gas steam boiler, heat insulating properties and thickness, the outside air temperature and the flow velocity.
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.
