electric heating industrial steam boiler for sale
Temperature protection device during the fuel steam electric heating industrial steam boiler for sale overtemperature protection to regulate temperature protection is an important part of safe operation of steam boiler fuel, especially fuel steam boiler temperature regulation and protection. Electric heating boiler and the boiler is mainly composed of electric control box and control system. Its characteristics are environmentally friendly, clean, no pollution, no noise, automatic, with limited energy and reduce prices significantly, as a new boiler electric heating boiler equipment increasingly being recognized. Electric heating the core member is electrically heated boiler, directly determines the life of the boiler, to select a non-metallic electrical heating tube (such as a ceramic heating pipe), because it is resistant to the load, a long life, and a water separation structure, the boiler Wing no leakage. Fuel gas boiler is not only fuel but also refers to the gas boiler. Previously no such dual-fuel boiler, burner because either fuel or gas, no dual fuel burners. With the rapid development of the world energy equipment, some European countries begin production and sales of fuel gas burner, dual fuel burner and boiler combination of organic birth of a new breed of boiler - fuel gas-fired boiler. Meanwhile, when the superheated steam boiler fuel, can play a role in the regulation and protection. Conventional boiler temperature protection means is a bimetallic temperature controller. Flame protection: To prevent the furnace blast, the fuel steam boiler must be equipped with flame protection device, and its function is combustion within the monitor cavity (including ignition misfire on or off in the middle of the combustion, is generally re-ignition within 5 seconds, within 1 sec. running off the oil (gas) solenoid valve, and opens the concurrent silent alarm signal, when the blower continues to operate, remove residual combustible gases in the furnace, after 20 or 30 seconds purge, and various auxiliary blowers automatically cut off power boiler stop running. flame monitor function signals displaying a flame presence or interrupt from the control device. its main use is a photomultiplier tube, photoresistors and photocells, they have an ultraviolet or infrared type photoelectric conversion element, its operating the principle of light radiation intensity is converted to the corresponding high current and low current and the output is a linear state, the induced current is sometimes weak, and thus affect the controller amplification.
Electric power operation a steam electric heating industrial steam boiler for sale steam boiler flame condition is a kind of power for energy conversion from electric energy into thermal energy, the hot water or organic heat medium (HTF) is heated to a certain parameters (temperature of the boiler through the heat exchanger portion, pressure) and externally output has a nominal thermal Machinery working fluid. The use according to electric boiler can be divided into: KS-D electric water boilers, CLDR (CWDR) electric boiler (including an electrical heating bath boilers and electric boilers), LDR (WDR) electric steam boiler. Electric steam boiler in the process of running, fireman personnel to observe the combustion flame, burning flame can burn if fully reflect fully, a number of other accessories such as whether there is a problem, then the fireman can be carried out according to the boiler combustion flame swap, in order to reach the normal combustion. If the flame exhibits electric steam boiler combustion yellow-orange, with neither white nor black smoke bright and clear outline, surrounded by non-sparking, fire smoke color other than transparent; size and shape of the flame at high fire to substantially fill the chamber but the phenomenon of flame swept and peripheral heating surface does not appear. In the case where the oil temperature, oil pressure requirements are met, such as the Mars entrained in the flame, it is possible that nozzle clogging. When the atomization uniform, the local flux density is too large, the presence of coarse particles or droplets, can see the flame root few black stripe, snow flake peripheral flame Mars large droplets combustion. If there is incomplete combustion of carbon black and outer combustible gas flame, the flame and smoke in rewinding the tail and around the flame, smoke opacity. Here the air volume should be adjusted, with the wind flame-inspection position of the disc, to remove the nozzle may hit coke.
Fangkuai Company has a fully-automatic PLC intelligent control system designed and developed by itself with complete intellectual property rights. It adopts a combination of mechatronic control equipment and a programmable logic controller (PLC). Take the advanced programmable logic controller (PLC) as the "central processing unit" of the control system. The control system is operated through the touch screen, which greatly improves the degree of automatic control and operation reliability of the electric heating industrial steam boiler for sale, and the operation is simpler and more intuitive.
Hot water electric heating industrial steam boiler for sales are classified according to what conditions according to different hot water boiler fuel can be divided into electric water boilers, hot water boiler fuel, gas hot water boiler, coal-fired hot water boiler; can be divided according to whether atmospheric pressure and two kinds of hot water boiler pressure hot water boilers, hot water boilers we usually call refers to the atmospheric pressure hot water boiler, due to its safe operation, people bathing or heating largely adopted this pressure hot water boiler. 1, the tubular assembly Computerized water boiler controller, all the functions are stored on a smart chip, intelligent, digital boiler, automatic, user-friendly, intelligent control of boiler water, water reaches the automatic stop heating; large-screen font temperature, boiler water temperature at a glance. 2, boiler water temperature can be freely set from 10 deg.] C to 100 deg.] C, the boiler can supply both hot water bath can provide water for drinking, may be a dual oven. 3, the top of the furnace through the air opening is provided, the boiler is in an unpressurised state, there is no danger of explosion, while the machine is equipped with thermal protection (ultra-high-temperature furnace during the heating tube buzzer alarm and automatically stop working, secondary overheat protection (boiler housing temperature exceeds 105 deg.] C, the secondary circuit is automatically cut off), anti-dry water protection (when the furnace is less than the water level is very low, the boiler is stopped and an alarm beep), etc. .2 number of security, pot such hot water boiler drum cartridge type hot water boiler, early mostly modified from a steam boiler made, which in the case of boiler water within a boiler of natural circulation. in order to ensure safe and reliable boiler water cycle, the boiler requires to have a certain height, so such larger boiler, steel consumption, and the cost is relatively increased. However, since this type of boiler capacity and can maintain the natural water cycle, when the system pump is suddenly stopped, the pot can be effectively prevented vaporization of water. it is also for this reason natural circulation hot water boiler in our rapid development.
