gas hot water boilers south africa

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.

Learn the difference between pay professionals work and waste boiler and boiler feed water for boilers of knowledge and understanding, we will continue this work, because the only way to keep abreast of professional knowledge about the boiler, and the knowledge and flexibility to apply their knowledge applied to practice, then, to ensure that the boiler had good results, avoid misuse. 1. What is the boiler professionals work? Boiler professionals work, the specific name for the boiler professional engineers and professionals work into operation and maintenance professionals work. Run professionals work: the development of operational procedures, technical monitoring in the boiler, if the boiler fails problems during operation, timely analysis and guidance to operating personnel discharge failure, ensure that the boiler safe operation. Also, record the operating parameters of the boiler, to provide accurate data for the boiler overhaul. Maintenance professionals work: development of maintenance procedures and maintenance scheduling and parts planning, at the same time, but also to develop maintenance programs, guidance personnel for maintenance work as maintenance procedures. Boiler feed water and boiler feed water 2. Is there a difference? Boiler feed water, which is from the plant to the Water and then through oxygen between the boiler feed pump into the boiler economizer soft water, boiler feed water is from the chemical water softener after the plant by chemical treatment. Although they are soft water, boiler feed water, but more complicated, but also the need for oxygen and heated before entering the boiler. So, boiler feed water and boiler feed water is different. 3. central boiler furnace temperature to be controlled in a range? The boiler is the first inspection within or outside the check? Central boiler furnace temperature is generally controlled within the required range of 900 ℃ -1100 ℃. Is the first in the boiler inspection, conducted after the external examination within the inspection is completed, if the problem has been found in the inspection process, and after dealing with external inspection out of the issue. In addition, we also need to know that, in the boiler inspection is conducted every two years, external examination is conducted once a year. 4. What is the waste boiler? Familiar with and understand the waste before the boiler, first look at waste boiler. Waste boiler, which means that the exhaust gas, waste and waste water. Exhaust: no fuel to burn in the combustion waste air emissions, mainly including soot, sulfur dioxide, nitrogen oxides and other waste gases. Waste: solid waste produced after combustion of the fuel, including cinder, oil residue and other such waste. Waste water: Some water is not used in the boiler emissions, comprising a compound, mixture, suspension, and salt, alkali larger boiler water, in addition, also water, sludge and the like fluffy precipitate. Waste boiler, which is the use of some of these techniques and recycling waste utilization, and reduce noise to produce secondary economic benefits.

Reform "coal to gas" boiler which change from coal to gas boiler to the enterprise transformation to the enterprise what changes bring? As an important measure to improve the air quality of our country, from coal to gas has been & all hot social topic. So, if the boiler from coal to gas, which will give users the benefits of it? First, to enhance the thermal efficiency of the boiler conventional coal-fired boiler mostly thermal efficiency of about 70%, a large portion of the energy due to heat loss or otherwise be wasted, after the coal to gas using the gas-fired boiler, the thermal efficiency will be 20% -40% increase . Second, lower investment costs than the price of coal gas prices high, but in addition to fuel costs, only the investment pipeline can. The investment in coal-fired boilers in addition to fuel costs, as well as transportation costs, labor costs, storage costs, the overall price is not cheap. From the cost point of view, natural gas overall advantage. Third, improve environmental benefits due to the combustion of natural gas itself is adequate, and clean burning, non-polluting emissions is a more environmentally friendly energy sources. After coal combustion emissions from sulfur, more ash, environmental pollution more serious, which is incomparable with gas boiler. Gas boiler can bring greater environmental benefits to the enterprise. Coal to gas boiler renovation project will enter a peak period, how to ensure that supply coal to gas projects as soon as possible and boiler manufacturers of high-quality products are a top priority. As one of the participants from coal to gas project, fast Boiler 0371-60922096 high quality, high technology, intelligent features, efforts to respond to the call of our coal to gas, and actively push green energy power production equipment, make the sky bluer, clear water make greener!
