oil fired fuel high pressure gas operated steam boiler

20 tph WNS gas-fired oil fired fuel high pressure operated steam boiler for milk products plantThe production and processing of dairy products require a large amount of steam to distill, disinfect, dry, and shape the food. The customer's boiler house is arranged in a single layer. After our technical staff visits the site and communicates with customers, ZOZEN decided to use two units of 10 tph oil and gas dual-use steam boilers in this project. This type of boiler adopts a mechanical and electrical integration structure, generous appearance, less investment in infrastructure; our boiler is strictly in accordance with the requirements of the customer to complete the standard, and we provide full equipment debugging, technical guidance, regular return visits, collection Feedback, which makes customer relieved and satisfied.

The main reason gas oil fired fuel high pressure operated 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.

Recently, Shaanxi Province issued a notice "issued four Battle 2019 program of work". Programs that: improve the mechanism of heating prices, heating prices reasonable development of clean, green electricity implement ultra-low emissions coal-fired power plants, a comprehensive clean canceled preferential tariff class of high energy-consuming industries unreasonable prices and other preferential policies. Off Area ban coal stove, substantially eliminated cogeneration heating pipe network coverage in the range of coal heated oven (furnace).

According to focus on the use of coal and clean use of principles, focusing on reduction of non-coal for electricity, increase the proportion of electricity from coal. Increase Condensing units and cogeneration units technological transformation efforts, speed up the heating pipe network construction, fully release and improve the heating capacity, eliminate coal-fired boilers and scattered inside the pipe network coverage. Actively implement alternative heat source, deadline for shutting down the Guanzhong area below 100,000 kilowatts thermoelectric ratio does not meet the national standard or alternative heat source thermal units. Optimal operation mode cogeneration units, strictly implement the "hot set electricity."

8 tph DZL biomass-fired oil fired fuel high pressure operated steam boiler for textile factoryHangzhou Yunsen Textile Dyeing and Finishing Co., Ltd. was founded in 1999 and attaches to the Zhejiang Yunsen Group. It processes color yarns, singeing, and filaments with a capacity up to 6,000 tons. ZOZEN boiler was commissioned by Hangzhou Yunsen Textile Printing and Dyeing Company and recommended a DZL8-1.25-M biomass-fired steam boiler according to the characteristics of Yunsen Textile Company. The ash discharged from the DZL8-1.25-M biomass-fired steam boiler can be directly used as farmyard fertilizer, which is a highly efficient, energy-saving, environmental friendly boiler product. The DZL8-1.25-M biomass-fired steam boiler has the characteristics of high calorific value and low cost, and its operating cost is only one fourth that of the electric boiler and less than one half that of the fuel (gas)-fired boiler.
