industrial PLC 3 pass fire tube gas steam wet back boiler
The origin of the gas on the principle of using gas steam industrial plc 3 pass fire tube steam wet back boiler steam heating boiler called gas steam boiler. HTF, also known as organic heat carrier medium or hot oil, use as an intermediate heat transfer medium in the industrial heat exchange process has been more than 50 years of history. Based forced circulation design and development of once-through boiler. Typically coal, oil, gas fuel to oil as the medium, using a thermal oil circulation pump to force the liquid circulating medium, the heat energy to a heat transport device and then return again heated furnace, having obtained at low pressure high operating temperature, and can perform high-precision control of the working medium run. High system thermal efficiency, easy operation and maintenance, the closed-cycle heat to the atmosphere, the service life, the liquid or vapor phase delivery extended heating boiler. Gas steam boiler return three-coil design, the system is set up expansion of the water tank, provides low temperature heating. Using the coil structure, sufficient heating surface, expands sufficiently absorbed. Imports of low NOX burner, combustion, are environmentally friendly products. Boilers can use advanced touch-screen computer controller and digital computer controller automatic control. Having a thermostat, automatic ignition, and differential pressure, over-temperature, flame protection. Boiler manufacturing practices, in strict accordance with the relevant national standards. The use of gas steam boiler water quality requirements: Some users believe that as long as gas steam boiler water is held on it, the water quality indiscriminately. In fact, the use of water or gas steam boiler influential, small advice you to choose clean tap water. Because if there are impurities in the water, then the use of this device with impurities of water will have some impact. Impurities junction thick layer of scale on the inner wall of the gas steam boiler. The scale will gradually thickened over time, which will affect the efficiency of heat conduction when a thickness of accumulation is wasted energy. If the scale appears to be cleared, so the heat is concentrated in the scale easy to distribute.
Fire industrial plc 3 pass fire tube steam wet back boiler design pitch is much: a room, boiler production plant belongs to class D, to a steam boiler rated evaporation 4t / h, when the rated output is greater than 2.8MW hot water boiler, the boiler room building fire resistance rating of not less than two ; rated evaporation steam boiler is less than or equal to 4t / h, when the hot water boiler is equal to or less than the rated output 2.8MW, between the boiler building fire resistance rating of not less than three; m-inter-tank, oil pump and the oil heater are inter production plant belonging to class C, not less than two of its construction fire rating, between said room is arranged within the auxiliary boiler room, a room should be set apart from other firewall; March and gas regulator production plant belonging to Group A, which building fire rating of not less than two, should be provided between the boiler room and the immediate neighborhood regulator firewall spaced boiler room, which doors should open outwards and should not directly access to the boiler room, the ground should not be spark Ping.
Fangkui Boiler aims to "warm the world", and we provide target customers worldwide with industrial plc 3 pass fire tube steam wet back boiler equipment and service guidance to meet their needs. At present, we have provided boiler equipment and solutions for customers in more than 80 countries and regions, including Russia and Bangladesh, to promote the production efficiency of customer enterprises.
Hot water industrial plc 3 pass fire tube steam wet back boiler for users to solve the "coal" urgent at present, energy conservation and building sustainable economic model has become a national priority, but only our coal utilization hovering around 30%, far below the 78 % of the international average. Steam boiler is an energy conversion device, the energy input to the boiler fuel chemical energy, electrical energy, thermal energy and other forms of high temperature flue gas, and after converting the boiler, the steam output having a certain outside thermal energy, high-temperature hot water or an organic carrier. Biomass boiler categories: biomass boilers Horizontal, vertical biomass boilers. Biomass gas thermal oil heaters, biomass steam boiler, biomass hot water boiler, biomass oil furnace. Gas-fired steam boiler burner underlying mode, two-pass configuration, the fuel combustion, the boiler operation is stable and take up less space, while the spoiler is inserted smoke tube, smoke slow speed, increase heat transfer, a high thermal efficiency, reducing user fees Therefore, improving the utilization of coal combustion has become essential. Currently, coal-fired hot water boiler control system to achieve precise control and real-time monitoring. By controlling the water temperature, the fan speed to achieve a controlled, to ensure the stable combustion furnace pressure and coal, which saves coal, but also to ensure safety. Industrial production in the boiler and heating primary energy into secondary energy of important equipment, has been widely used in industrial production and daily life. Coal-fired hot water boiler control scheme is reasonable and convenient way to monitor, steady state operation, the whole process of thoughtful service, users get a good feedback. I believe in the future, coal-fired hot water boiler intelligent control scheme can serve a wider field of industrial production, as well as hotels, schools, hotels, residential heating, bath, hot water and other fields, coal cost savings for users, improve combustion efficiency, ensure the safe operation provide a solid guarantee. Completely solve the problem of long-term accumulation of the user, the water temperature stable. Water temperature set by the ambient temperature, grate speed difference adjustment according to the actual water temperature and the set temperature of the water, i.e. adjusting the amount of coal boiler, to ensure the stability of the water temperature. Outstanding energy saving. Grate speed changes to the feedforward signal, in conjunction with flue gas oxygen content signal or the furnace temperature, blower speed control using the PID algorithm, to ensure full combustion of the coal, to improve the utilization of coal, reduce emissions of harmful substances. Excellent safety performance. To change the fan speed as a feedforward signal, the PID control calculation and induced draft fan speed according to the furnace pressure value, to ensure the stability of the furnace pressure. This paper introduces a control algorithm based on the level of intelligence of the new big jump lag PID. After control of embodiment, given a certain waiting time to observe the effect, and to determine whether further embodiment control, multi-parameter input and multiple output control mode based on performance parameters.
