Working principle and structural characteristics of steam boiler

Steam boiler has brought great convenience to industry. Steam boiler has driven the development of the times. The following is a brief introduction to the structural characteristics and working principle of steam boiler. Steam boiler is a machine that mainly produces steam, and many people use it, but many of them do not know much about its structure and working principle. It makes use of coal, oil, natural gas and other water-tube steam boilers with limited capacity and pressure. There is a large desire to space, and easy to arrange, steam boiler in a variety of forms. Water is heated in the drum into steam, and the heat emitted by fire in the furnace is the principle of a steam boiler. Work of steam boiler Principle:

1, the heat generated by pulverized coal combustion in the furnace is first absorbed by the water wall through radiative heat transfer, and the water boiling of the water wall is vaporized, producing a large amount of steam into the steam drum for steam separation (except for direct flow furnaces). The separated saturated steam enters the superheater and continues to absorb the flue gas heat at the top of the furnace and the horizontal flue and the tail flue through radiation and convection, and enables the superheated steam to reach the required working temperature. The steam boiler for power generation is usually equipped with a reheater, which is used to heat the steam after the high-pressure cylinder does work, and the reheat steam comes out of the reheater to go back to the middle, and the low-pressure cylinder continues to do the work to generate electricity.

2. When the pulverized coal stove is working, The position of the center of the flame will affect the amount of evaporation, generally speaking, if the center of the flame is low, the amount of evaporation will be large, and the position of the center of the flame will also affect the temperature of the superheated steam or reheated steam, as well as the high value of the flame center and the small amount of evaporation. When the flame center is low, the superheated steam, especially the reheated steam temperature, will be low and vice versa.

3, the arrangement of burners, as far as coal powder furnace is concerned, there are many kinds of combustion modes, such as front and rear wall, tangential combustion, double tangential combustion, and so on, each of which has its own characteristics. The influence on steam can not be directly determined because the same furnace can not apply the above-mentioned arrangement methods at the same time.

Henan gas boiler control system configuration Henan microcomputer controller for a gas boiler, a large screen Chinese LCD screen with bright backlight, day or night, Henan gas boiler operating state is clearly visible. Display complete: circulating pump, the operation of the burner, the boiler water temperature, water level, the current time, alarm records, Henan readily available gas boiler operating state; easy setup: the boiler power, the operator can key 6 for operating parameters at the time by going to the standby state (set) into the operating state (power on), the state out of operation (stop), the random standby state is set; functional: arbitrarily set the current time, alarm temperature, the upper limit temperature temperature, water temperature lower limit temperature, the temperature of the circulation pump is turned on, the circulation pump shutdown temperature, the boiler switch time (divided into four time periods) and other operating parameters. The operator usually just press "Start" key to boot, press the "stop" button down, is very simple. First, the characteristics 1, arranged brand combustor inlet, a high degree of automation, automatic purge controller according to the instruction, the electronic auto-ignition, spontaneous combustion, air oil (gas) automatic ratio adjustment, security and stability performance, good combustion. And there are flameout protection device, ensure safe operation. 2, the computer controller of formula bath gas boiler, all the functions are stored on a magic smart chip, a key to boot Henan gas boiler, automatic timing, temperature operation, the user can set the start, shutdown time setting is completed after, no special duty to save time, and effort. 3, the inner fire tube inserted spoiler retardant, smoke slow speed, to strengthen the heat exchanger, the temperature of the flue gas discharged from a low smoke chamber, reducing heat loss and save fuel. Second, the operation 1, a large font display temperature, easy to grasp the operation status of the gas boiler and system Henan, the water temperature can be freely set from 10 ℃ to 90 ℃, Henan gas boiler automatic system to provide users with live or heating, bath with hot water . 2, the control system controls the circulation pump start and stop in accordance with the temperature of boiler water, boiler water circulating pump starts when the water reaches an upper limit temperature, lower than the hot water circulation pump stops when the water temperature lower limit. 3, three horizontal gas bath boiler return all wet back structure, using a large furnace, rough smoke tube design, increased furnace radiation heat absorption, the effective energy saving. Using threaded pipe and waveform furnace, greatly enhanced heat transfer effect, greatly saving fuel consumption. 4, while the machine is equipped with thermal protection (ultrahigh temperature furnace, the burner is automatically stopped and an alarm buzzer, the second over protection (Henan gas boiler housing temperature exceeds 105 deg.] C, the secondary circuit is automatically cut off), anti-dry burn water protection (when the furnace is less than the water level is very low, the gas boiler is stopped and an alarm beep), a boiler leakage protection (the control system detects electrical leakage, short circuit, automatically cut off the power) .5, Henan gas boiler press pressure design, the boiler is in the non-pressure state, there is no safety hazard. centrifugal using advanced multilayer insulation wool, a steel sheet for packaging famous white color, heat loss, anti-rust appearance.

The transformation of our country more energy-efficient oil-fired boiler boiler more than ten years ago when coal-fired boilers is widespread, as many big cities like London to become a fog; started to improve boiler, which is the traditional coal-fired boilers to improve fuel boilers. So how does the market more than a decade after the oil-fired boiler? Let's six tons of fuel oil boiler as an example. Many boiler plant now do not produce oil-fired boiler, and someone asked why ah? Just one reason, fuel is too expensive, customers are concerned about operating costs are too high, and the boiler plant produced worried about the unwanted, and finally makes us a headache . But with the advancement of our product diversification can not blindly out of old products! Should think of ways to see if I can improve through various efforts, Henan party fast stock finally developed a more energy-efficient oil-fired boilers to improve even more cost-saving program, Here we give you the share: examples of transformation of energy boiler fuel oil boiler economizer installation ①; ② mounted condensing type gas boiler economizer; ③ using condensing heat recovery boiler technology; ④ rear of the boiler heat recovery heat pipe technology; ⑤ using scaling, cleaning technology; ⑥ use of fuel additive technology; ⑦ new fuel; ⑧ using oxy-combustion technology; ⑨ using swirl combustion boiler technology; ⑩ use of air source heat pump water heater replacement techniques so many customers ask this fuel more energy-efficient boilers to improve What is the price? Henan square to welcome you soon share online consultation.

Our preliminary investigation when the other side is very interested in fast boiler, a number of fast-party research and development as well as outstanding patent cases in all industry sectors, we have confidence in each other quickly this brand. After the cooperation, but also the strength and each staff fully aware of the fast boiler of a good attitude, and cooperation in the box, very at ease. --customer feedback
