When the pressure of the steam boiler protection small small steam boiler pressure exceeds the rated boiler steam pressure protection, the need for chain protection: is shutdown, the system stops the combustion; fire mouth can also be varied, single-stage or two-stage combustion, You can adjust the amount of oil, so the buck, to ensure the safe operation of the boiler. Fuel (gas) pressure protection and steam boiler water, as the use of multiple protection: the pressure controller typically use two pressure controller, the pressure signal converted to an electrical signal, the electromechanical converter, the function of the high pressure, or low levels of signal The electrical switching loss, external circuits or automatic control chain protection. Common pressure controller and pressure gauge, vapor pressure overpressure alarm can cut off the burner limit is reached; pressure controller adjusts single fire or dual fire burning the actual operating pressure; for large burner, the pressure may be adjusted according to the size of the size of the amount of fuel, and always maintain a stable pressure relief valve operation is the last line of defense to protect the boiler, the boiler pressure exceeds the limit, according to the set pressure relief valve design feature, the exhaust pressure relief, to ensure the normal operation of the boiler. Temperature protection temperature protection is an important procedure in the safe operation of the boiler, is particularly important for the regulation and protection of the boiler temperature steam; at the same time to regulate protective role in over-temperature lpg fired hot water boilers. Conventional boiler temperature protection means is a bimetallic temperature controller.
The main reason gas steam boiler produces smoke which fuel gas steam boiler main cause of smoke. A fuel gas steam boiler: oil, gas oil quality is not good when the gas contains more water, reduce the heat value of the fuel, while producing steam, the furnace temperature tends to decrease, making it difficult to burn, easy to produce smoke. Water and more oil, mainly when unloading rain water into the oil during heating the oil in water vapor penetration. When the oil contains impurities, the impurities unburned produce fine coke, the coke into fine smoke, dust becomes large, and the formation of soot. Impurities contained in the oil and gas, but also affect the pure oil and pure combustion gas generated soot. Oil impurities, mainly due to inappropriate choice of filters or filter difference impurity removal effect. Second, the failure of the fuel atomizing nozzle member main burner fuel oil atomizing nozzle. Atomizing oil burner nozzle fails, affecting the quality of the atomization, easy to poor combustion. 1, the adhesiveness between the bonding surface of the oil and the consequences of failure oil atomizers swirl atomizers and the splitter plate well, leakage will occur, atomized large oil particles, increasing the amount of fuel injection and the like. In this case serious deterioration of the quality of the combustion, the oil droplets have landed on the water wall, stacking up oil coke, partially unburned black smoke into droplets. The tangential swirl chip groove clogging mist causes uneven density distribution in the dense side of the oil mist, combustion air be insufficient. In the more dilute side of the oil mist, combustion air causes severe local excess. Mixed with oil, wind conditions deteriorated significantly, combustion conditions deteriorate, resulting in black smoke. 2, spray atomization slice failure and the consequences of failure to clogging and wear. Nozzle clogging, resulting in blockage of the fuel injection quantity is not glib increase, oil particle size thicker, the effect of fuel poor and black smoke. Wear injection port, a large hole diameter, increasing the amount of fuel injection, increasing the particle size of oil affect combustion efficiency, produce black smoke. The use of artificial gas burner, naphthalene and tar and other impurities will block the nozzles, the influence of gas distribution, resulting in black smoke. Should therefore be cleaned regularly, or clogging of the selected burner. 3, the partition partitioning poor poor, insufficient supply of air into and excess. The amount of air can not meet the requirements of the fuel combustion, so that combustion of fuel can not be sufficiently black smoke. The amount of air, will result in lower combustion temperature, black smoke and fuel difficult to burn. 4, the furnace temperature is too low when starting the furnace, fuel oil steam boiler furnace temperature is too low due to easy black smoke. 5, the furnace hearth product oil is sometimes caused by internal combustion nozzle oil accumulated inside the chamber, the oil reservoir coke black smoke at high temperature. Causes dripping of fuel combustion nozzle: ① The drip just work, just at the operating pressure is too low, the oil will flow from the nozzle, instead of the discharge. The reason for low oil pressure is a solenoid valve, the valve is clogged filter or the like or failure caused by contamination. ② In the dripping process work, probably because the relative position of burner nozzle mounting head too far, improper ignition electrode position, the oil into the atomizer, the nozzle holder is mounted is not tight, nozzle dirty, low oil pressure caused. ③ When the dripping stopped, because the line between the pump and the air nozzle, electromagnetic valve or a hydraulic valve or dirty failure. 6, the furnace flue purged countless consequences when the furnace flue remnants of oil and gas, when gas purging endless, high temperatures encountered in the explosion and black smoke. 7, the furnace smoke, sparks, the furnace pressure is too ①; ② inappropriate choice of the burner, the burner flame is too long or too much power; ③ improper combustion ratio, there are more to produce products of incomplete combustion; ④ atomization quality is not good nozzle or improper installation location, or affect the combustion flame into the furnace off port; ⑤ flue is blocked, poor smoke; ⑥ a secondary air mismatches; irrational ⑦ furnace structure; ⑧ oil spray angle is selected from with improper.

What is different from the lpg fired hot water boiler and steam boiler there? There are many companies will operate on steam boilers do this relatively high cost of care. After the scene since the late boiler equipment, equipment up and running is a big sum of costs. About enterprise, if choose for their own fuel boilers, boiler fuel efficiency will make use of further progress. Therefore, we demand that the cost of running on several different fuel steam boilers budget to know. Gas: Advantages: clean energy, high thermal efficiency, low cost. Disadvantages: gas adapter constrained condition. Produce one ton of steam costs about 240 yuan (gas prices by 3 yuan / square meter accounting). Fuel: Advantages: no pollution, high efficiency, no fuel constraints. Disadvantages: higher operating costs. About 594 yuan one ton of steam production costs (fuel prices accounted for 9.0 yuan / kg). Electric heating: advantages: no pollution and no fuel constraints. Disadvantages: is a secondary energy, high operating costs, the cost of producing one ton of steam is about 700 yuan (price 1 yuan / degree). Coal: Characteristics: low operating costs. Disadvantages: severe pollution in some areas, the use of restraints, cost of production of one ton of steam is about 150 yuan (coal prices by 1,000 yuan / ton accounting). Heat boiler is an important means to transfer heat to the appropriate fuel equipment, it is now being widely used in industrial production and heating and so on. Popular in the size of the boiler is a steam boiler and hot water boiler both types, many people who only know the boiler heating equipment, but can not tell in detail parting boiler. Today we gave Shandong steam boiler explain what the differences steam boilers and hot water boilers, after all, what! On the surface, we can understand heating hot water boilers and steam boiler heating method chosen is not the same, but the distance between the hot water boiler and steam boiler Moreover, detailed in what areas? The different output media we literally can be seen, the medium is hot water output from the boiler, medium boiler steam output of the steam. First, the user can according to their demand for the output media, choose the appropriate boiler. Different steam boiler space occupied by a high pressure vessel, through steam forming water is heated after the completion of the vapor compression heating, and the area of the pressure vessel by the use of less water boiler is an unpressurized vessel by virtue of heat temperature of the water to complete the heating, hot water boilers professional usually occupied by a larger location, but better able to complete the non-selection of the pressure vessel safety are better able to ensure the safety of those who use. Because the size of different heating and heat storage capacity of water vapor from a large, high-volume hot water boiler and thus be able to choose long-distance transport of heat pump delivery lost less able to complete large-scale transport of hot water requirements. The steam boiler because the steam freezes faster, so in the long-distance transport can lead to sudden drop in water temperature, so the size of two kinds of heat supply boiler equipment can withstand different. Heating steam boiler at different speeds when using the heat generated as the water transpiration and thus burn calories in order to ensure the needs of large steam generation, and thus the temperature rise faster fever faster speed; hot water boiler heated water to ensure that the temperature of the water in the use of Yung heat better, thus better able to maintain the heating heat.
