The main factors affecting small type gas industrial or oil steam boiler steam boiler thermal stability of gas ignition is not difficult to establish a stable small fire signal, the root cause is a small fire detectors can not detect normal to the fire. 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 biomass boilers categories: biomass boilers horizontal, vertical biomass boilers. Biomass gas thermal oil heaters, biomass steam boiler, biomass hot water boiler, biomass oil furnace. Function gas boiler the ignition system that ignites the mixture of air and fuel, its main components are: the ignition transformer, the ignition electrode, a high voltage electrical cable fire. A more secure electronic ignition system called ignition pulse, is widely used Zhuoyi energy saving gas boiler manufacturers. Which facilitate saving, can simply press a finger, and safe, does not occur due to unexpected accidents occur flame, once the stall state occurs, the control system can close the solenoid valve, off the gas passage. Small fire detectors use the ionization fire detection, and requires effective contact area of the flame, the flame stability and proper size, the gas pressure must be controlled within a very strict range. If the ignition gas pressure is too high, too long a small fire flame is moved beyond the detection range of the small fire detection probe, the system will not be mistaken for a small fire; if the gas pressure is too small, the gas will be firing too small and the boiler the blast very, very easy to blow out the flame, the ignition is not possible. Also, fire gases found a small pressure regulator valve regulating performance is not good, fine adjustment can not be achieved. Stability is also related to a small fire and the ratio of the size of the boiler furnace pressure boiler feed valve. The damper is too large or too small can affect the stability of the flame is ignited and the flame, furnace pressure will lead to extinguish the flame. In order to ensure the accuracy of fire detection, fire detection, we can adjust the small depth of insertion of the probe, the position of the fire detection probe in the correct position, in order to more effectively detect small fires flame.
Category Description oil-fired boiler fuel gas-fired boiler is different from coal-fired boilers, which requires the use of a burner fuel is injected into the boiler furnace using a combustion chamber without the use of fire grate facilities. Because not produce fuel ash after burning fuel gas-fired boiler, fuel gas-fired boiler so without slagging facilities. If the hydrocarbon injected into the furnace with the air mixing within a certain range, or turned off, it is easy to explode. Therefore, fuel gas-fired boiler combustion required to adopt automation and control systems. Fuel gas boiler compact, small boiler and ventilation, water supply, control and auxiliary equipment are arranged on a chassis, the assembly may also be medium-sized factory. Boiling water boiler fuel oil boiler fuel, also known as water heaters, stove oil, furnace fuel tea, water boiler fuel, is living in a boiler, belong to the category of civilian atmospheric boiler. The boiler is a fuel oil as fuel by a burner to heat the water, when the water temperature reaches the set temperature (water), the burner stops working, heat boiler into the automatic state, the user starts to provide water, oil and water if the boiler holding tanks connected to meet like hospitals, schools and other centralized water supply demand type units. Hot water boiler fuel oil hot water boiler fuel refers to fuel have mainly boiler fuel hot water boiler with a high-tech automatic control system, with a number of security devices, water protection, overpressure protection, flame protection abnormal pressure protection, over-temperature protection flue; using high-tech structures, having a body holding a small, compact and easy to install, simple operation, automatic adjustment, the pressurized fuel to the atomizer, and then allowed a slight positive pressure fuel combustion burner more fully, to reduce the loss of gas emissions and fuel, it is a modern industrial steam to use the most convenient and most energy-efficient, environmentally friendly standard products. Fuel industrial or oil steam boiler fuel (gas) steam boiler, a horizontal combustion all wet back, efficient threaded pipe, with a sound insulation outsourcing design, the boiler thermal efficiency as high as 85% or more, product design, rational structure, process performance is good, so that this product has extraordinary excellent quality.
June 22, 2018 in the evening around 6:40, Chongqing Hechuan keel village "Ding taste the food factory" boiler 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.
