Steam simons boiler electric and coal steam boilers hots What is the function? Too many in the form of steam boilers, would like to give a quick four tons of ordinary steam boiler talk. Water in the steam drum is heated to become vapor, fire emits heat in the furnace, it is the principle of the steam boiler. Let me say a boiler pot. This boiler is a boiler drum with a water cooling wall at about the subregional arrangements drum pyrotechnic two return pipe, before the folded portion of the drum front smoke box. Between the drum and the tank in connection with the downcomer tubes and water-cooled bi, constituting the frame of the combustion chamber. There upper steam separator drum to reduce the water vapor out of the tape. Pan heating surface of a lower portion of the drum, and the water cooling pipe bi pyrotechnic tube. A chain grate combustion section and drive means, coupled with the combustion chamber pan rack on the frame configuration composed of the grate. Four weeks envelope refractories. . From coal fired into the hopper, the shutter coal front portion while sealing air control seam thickness. Blast into the lower part of the combustion chamber is a place that boiler greater resistance, need to force the blast. Cinder burn out, through the grate in the rear portion of the olecranon iron discharged from the machine to send out of the furnace slag. The boiler flue gas from the rear, by the front drum smoke tube a return line, the return from the two rear return smoke tube, and then into the dust separating ashes, and then discharged through the chimney draft fan. Not only is the induced draft fan exhaust fumes, the negative pressure of the boiler operation is required. Steam boiler pressure vessels, safety devices is necessary. Boiler necessary water level gauge, pressure gauge, safety valve, thermometer, and under the pressure of the electric pump can pay, and the vapor pump when power is off can also be used. Boiler water must be softened, as well as water treatment equipment.
Open the presentation characteristics of gas-fired simons boiler electric and coal steam boilers hot gas boiler includes a gas water boiler, gas hot water boiler, gas steam boilers, gas hot water boiler which is also known as gas heating boilers and gas boilers bath, as the name suggests refers to the gas boiler fuel for the gas boiler, gas boilers and oil-fired boiler, electric boiler compared to the most economical, most people have opted for a gas boiler as steam, heating, boiler equipment for bathing. Gas boiler features introduced large font display temperature, easy to grasp and boiler operating conditions of the system, the water temperature can be freely set from 10 ℃ to 90 ℃, automatic boiler or heating system to provide users with life, bath with hot water. The control system controls the temperature of the boiler water circulating pump start and stop, 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. Horizontal bath gas boiler three 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. Machine equipped with thermal protection (ultrahigh temperature furnace, the burner is automatically stopped and an alarm buzzer, the second over protection (the boiler shell temperature exceeds 105 deg.] C, the secondary circuit is automatically cut off), anti-dry water protection (when the boiler water level is below low, the boiler is stopped and an alarm beep), a boiler leakage protection (the control system detects electrical leakage, short circuit, automatically cut off the power). press pressure boiler design, the boiler is no 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.
Compared with steam simons boiler electric and coal steam boilers hot, why steam boiler is replaced by electric heating boiler requires higher production and use, and the pressure increases with the increase of temperature. In recent years, the new thermoelectric heat transfer oil furnace is also called organic heat carrier heat transfer oil furnace. We are usually called heaters. It uses electricity and combustible gas as energy source and heat transfer oil as heat carrier. High export oil temperature of 400 c, thermal equipment and hot water connected more environmentally friendly, more energy-saving. Compared with steam boiler, energy saving can reach 40% ~ 55%. Electric heating and conducting oil furnaces are used in the cycle. Different from steam, steam is discharged directly after use, and the waste heat can not be recovered. Heating stability The temperature adjustment is accurate. The heat transfer body in boiler and pipe is stable, unlike steam temperature fluctuation in steam boiler system, electroheat and boiler are beneficial to microcomputer automatic control. Electric heating oil heaters are safe at low and high temperatures and are heated to 340 degrees under atmospheric pressure without evaporation. Using steam to reach the same temperature, saturated pressure is 14.593MPa. Hot water boilers must be at a certain pressure in order to achieve a higher water temperature. If you want to get a temperature of 280 degrees Celsius, the pressure should be 6.412 MPA. Therefore, the heater has good safety performance. Electric heating heat transfer oil furnace The advantages of low cost, small investment, convenient manufacture and so on. Because of the low operating pressure of the heat transfer oil furnace, it is obviously easier to manufacture than steam boiler and hot water boiler, and the cost is low and the investment is small. Generally speaking, manufacturers with class E boilers or one or two pressure vessels have the ability to produce hot oil stoves.
June 22, 2018 in the evening around 6:40, Chongqing Hechuan keel village "Ding taste the food factory" simons boiler electric and coal steam boilers hot exploded, the accident killed two people, three people were injured.
At the scene, boiler room Zhata, damaged boiler flew ten meters outside the field, next to a few factories are subject to different degrees of damage, around the ruins. But because not many nearby residents, no adverse impacts to other villagers.
According food factory owner friends when the accident occurred, both inside and outside the boiler room just five people. One person was killed and four people were injured, one of whom died en route to hospital, the other three in stable condition and is currently being treated in. It is understood, Ding taste the food factory is a small tofu factory, usually only a few factory workers. When the accident occurred, it is time off work, the boss's father, Huang uncle went to the boiler room, prepare a little help, but I do not know which part of improper operation, resulting in an explosion.
The boiler explosion, resulting in serious consequences and impact, but also sounded a warning for the steam boiler is using various food processing plants. Steam boiler output to high-temperature steam, with a certain risk, in use, to operate in strict accordance with the provisions, not miss any details, nor allow non-professional staff stoker boiler operation to avoid unnecessary losses.
