natural gas boiler in steam power plants

A heated boiler in steam power plants is called a boiler. Heat transfer oil, also known as organic heat carrier or heat medium oil, has been used as intermediate heat transfer medium in industrial heat transfer for more than 50 years. Based on the idea of forced cycle design, a once-through boiler is developed. Generally, coal, oil and steam are used as fuel, heat conduction oil is used as the medium, hot oil circulation pump is used to force the medium into liquid phase circulation, heat energy is transmitted to the heating equipment and then returned to the heating furnace for re-heating. High operating temperature at low pressure, and high precision control for medium operation. The heat utilization rate of the system is high, and the transportation and maintenance are convenient. The closed circulation heat supply is connected with the atmosphere, can extend the service life of the boiler, liquid phase or gas phase transportation heating. The boiler adopts three-way coil design, the system sets the expansion water tank, and realizes low-pressure and high-temperature heating. The coil structure is adopted, the heating surface is sufficient, and the expansion is fully absorbed. Imported low-NOX combustion machine, combustion charge, belongs to environmental protection products. Boiler can choose advanced touch screen computer controller and digital computer controller automatic control system. With automatic temperature regulation, automatic ignition, and differential pressure, overtemperature, quenching protection. Boiler manufacturing standards, strictly in accordance with the relevant national standards. Pot The use of furnace water quality requirements: some users believe that as long as the boiler to maintain water can be, the water quality is not a choice. In fact, the quality of water on the boiler or have an impact, the editor recommends that you choose clean tap water. Because if there are impurities in the water, the use of this impurity water will have some impact on the equipment. The impurities form a thick layer of scale on the inner wall of the boiler. Scale will gradually thicken with time, and the accumulation of thickness will affect its heat transfer efficiency, resulting in a waste of energy consumption. If the scale appears, it should be cleaned up in time, so that the heat can be concentrated in the scale, which is not easy to emit. .

Boiler multiple protection: (1) the integration of boiler in steam power plants water level to protect water level and boiler design, the appearance of more compact appearance, accurately show the actual water level in the boiler body function. Coupled with dual independent electronic water level control system to achieve ultra-low water level in the boiler, low water level automatic adjustment function, the normal water level, high water level, ensure that the boiler in a variety of unforeseen circumstances foolproof, secure home. (2) steam pressure protection ☆ pressure controller: selection of high sensitivity of the pressure controller, the pressure is high, or low levels of signal to the electrical switch, other control lines or automatic control chain protection. Common pressure controller and pressure gauge, vapor pressure overpressure alarm can cut off the burner limit is reached; the pressure controller may be single or double fire burning fire the actual operating pressure regulator. ☆ safety valve: safety valve is the last line of defense to protect the boiler, the boiler pressure exceeds the limit, according to the set pressure relief valve design with the school, the exhaust steam pressure relief, to ensure the normal operation of the boiler. (3) having a burner flame protection flame protection inlet means, combustion function is to detect, when the ignition failure or extinguish combustion middle, immediately off the burner into the oil (gas) solenoid valve, the blower continues to operate at this time, the furnace was purged combustible residual gas, after 20 to 30 seconds purge, and various auxiliary blowers automatically cut off power, the boiler operation stops. (4) self-locking power failure protection case, the boiler shutdown immediately burst self-locking power interruption, if the current power is restored, the boiler will not start at any time, you must reset release self-locking, to re-start the ignition.

What if there is wear and tear in the natural gas boiler in steam power plants? Detailed inspection is the key, as is fuel management. According to the operation condition and time of natural gas boiler, we can plan reasonable wear inspection. When using fuel, we strictly control the granularity of coal and limestone. The size of bed material should be strictly controlled. Boiler waste should be disposed of. The waste residue of the boiler must be treated before it can be discharged. Natural gas boilers should be installed where heat is used, easy to install. The hot pipe should not be too long. It should have a good insulation. The pipe shall be tilted properly from the hot water outlet to the end. The water supply source shall be equipped with a control valve. To discharge exhaust gases, the chimney of the natural gas boiler should extend to the outside and the outlet should be 1.5 to 2M higher than that of the boiler. If we want to reduce the influence on the water wall tube, we can adjust the air pressure and air volume properly, and effectively reduce the wear of the water wall. Check time is usually standby or downtime. Items to be examined include wall wear, furnace sealing and smoke leakage. In case of wear and tear, repair and welding are required to ensure the normal operation of steam boiler. Generally speaking, before combustion of natural gas boilers, fossil fuels, fossil fuels and bed and circulating materials should be filled in the combustion chamber at wind speed and strength. And stiffness of the air convection under full integration. Furnace bottom air device, inner core area upward. The movement in the outer ring region flows downwards along the water wall of the furnace, thus prolonging the residence time of the coal particles in the furnace. Mineral particles, a large number of ash powder and smoke contain a large number of fly ash particles, these continue to lead to rapid wear of water-cooled wall tube, make wall thickness wear thin, resulting in wear.

For more than two decades, it has been the focus on clean boiler in steam power plantss, the insistence on precision and wisdom, and the pursuit of exquisite craftsmanship that have made today's Fangkuai boilers. Fangkui Boiler will always be based on the boiler industry, and will return customer support and trust with brilliant results and sophisticated technology.
