Maximum level (c) Installation of boiler network (1), water supply conduit installation requirements typically require as backup pool below the normal water level line of the boiler, so as not to shutdown, boiler feedwater flowing into a large number of drainage caused to start the next . At the outlet of the tank (i.e., an inlet feed line) should be installed wire screen. (2), a main steam line installation requires the main steam lead pipe straight run section should be more than 0.5 m, the bending radius should be 4-5 times the diameter of the pipe, the trap should be fitted at the lowest line in order to prevent water hammer pipe, while to be reliable insulation. (3), the safety valve should be installed in the valve installation requirements after the hydrostatic test, the safety valve shall be fitted exhaust pipe, the exhaust pipe of the safety guide outside the boiler house, allowed valving the exhaust pipe. (4), mounting a lower water table level table downcomer must access a safe place, Hancock rotating flexible water table, not leaking, water table must be installed to the lighting device, easy to observe. (5), a pressure gauge mounting means so that when the scale gauge vertical plates, should be painted red gauge scale to show the maximum allowable pressure boiler, rotating flexible plug gauge, not leaking, water flow, pressure gauges insulation prohibited. (Iv) the boiler chimney installation requirements, when lifting the chimney, the chimney should be straight, horizontal direction lead length should not be too long, generally less than 5 meters, the height of the chimney should comply with relevant national standards. To add chimney rain cap, the weight of the chimney should not fall directly on the boiler chimney take over the host. Installation (e) combustion system: 1, according to the combustion system of FIG power line control circuit, a control signal line and the control line is electrically connected, the program should be installed reliable ignition and flame failure protection devices. Combustion process controller provides a separate set of contact start-stop control. May be formulated in a variety of burner start-stop loop cascade control relay 10A is a fuse, relay start-stop control stops the control terminal may be connected to the burner, may directly control the power of the burner. Both constant pressure sensor, water power, fuel, gas pressure set value is detected after the automatic controller opens. Time pressure sensor, water supply, oil, gas, and their detection circuit, alarm and found the problem immediately shutdown flame protection, the controller automatically displays the point of failure, an alarm sounds machine.
Gas Steam Boiler Water Wall Tube Explosion Analysis and Processing With the west-east gas project in-depth and complete, and the "coal to gas," the implementation of Beijing, Urumqi, Daqing and other cities and district heating heat source to promote the use of gas-fired boiler . More commonly used gas-fired boiler type D, type 0, A-type, p-type [1-2], these four basic types of furnaces by dividing the furnace cross-sectional shape. Wherein, D, 0, A-type small capacity boilers belonging horizontal boiler, boiler Ding is a large vertical boiler. The four furnaces are used membrane wall structure, eliminating the flue gas leak, reduce heat loss and improve the thermal efficiency of the boiler, ensure the stability of the structure. A compact, short installation period, high thermal efficiency, low noise, low energy consumption, low emissions, long life (design life 30a), adaptable load fluctuations and other characteristics can be controlled by computer program running faults and Protective function. Domestic slightly less than the amount of evaporation experience in the development of high-power gas made in china fired steam boiler in the 75t / h or more, most of the development work is based on the introduction of Europe and learn from small gas steam boiler above. China's own design of high-power gas steam boiler in the course of running more than a vibration, burst pipes and other problems. This paper discusses some evaporation of the squib causes and treatment of boiler waterwall 160t / h of a gas steam.
Electric made in china fired steam boiler of the heating process due to elevated water temperature within electric steam boiler, heating and evaporation of the bubble surface of the metal wall temperature begins to rise at any time. There are heating and hot water boiler bath for two purposes. Hot water boiler by circulating hot water circulation pump hot water holding tank, the tank hot water heating cycle can be achieved bath object; hot water boiler by circulating hot water circulation pump heating conduit, through the heat sink (radiator) people can achieve heating requirements; hot water boiler and hot water circulating pump with heat exchanger can be achieved bathing and heating dual function. 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. Since the bubble greater wall thickness, in the electric boiler of the heating process, the thermal stress is a major problem, it is necessary for the thermal expansion of the bubble temperature and thermal stress study. At the same time, also considering the overall thermal expansion problems, especially an electrical heating surface tube steam boiler, since the thin wall thickness, length of problems in the process of heating the whole of the problems of thermal expansion, it should also be noted that the thermal stress. Prevent inadvertent failure caused. In the process of generating steam and processing the thermoelectric pressure steam boiler, when the temperature is higher than the outer wall temperature of the inner wall, the upper wall at a temperature above the wall temperature, the wall thickness and the temperature difference between the upper and lower walls of the bubble there is a temperature difference, i.e., bubble the inner wall temperature above the temperature of the outer wall, the wall temperature is higher than the wall temperature, the temperature difference between the thickness of the bubble exists in the thickness direction, the upper and lower walls of the larger temperature difference between the bubble, when the temperature is higher than the outer wall temperature of the inner wall, the wall temperature is higher than the wall temperature. In order to prevent excessive thermal stress, it is necessary to gradually increase the pressure of the boiler. In the process of electric spark and boost steam boiler, the steam parameters of the boiler components, water and conditions are changing. Therefore, in order to effectively prevent the occurrence of abnormal conditions and other hazards, it is necessary to arrange a variety of instruments to monitor closely the instruction of professional change. Within the normal allowable range, but also the reliability and safety of various instruments, valves and other components was evaluated by adjusting the process parameters pressure, temperature, water, etc., in order to fully guarantee the security of the electric steam boiler stable operation. The higher the electric steam boiler pressure, the higher the energy, the corresponding steam plant, pipes and valves can withstand the pressure will increase, which also makes the maintenance and protection requirements of the steam boiler is relatively high. In the production and transportation, and the ratio of heat loss will increase the share of the steam.
