2Th Heavy Oil Fired Steam Boiler

Safe use of chemical plant 2th fired steam boilers and safe use of chemical plant maintenance measures and maintenance measures of a steam boiler, steam boiler how to prepare for chemical corrosion: preparedness, it is necessary to analyze the problem from the root, it is necessary to corrosion from steam boiler elements lead to corrosion of departure, to find a solution. In principle, resulting in steam boiler corrosion is an electrochemical corrosion. Boiler film surface layer of the electrolytic solution absorbs moisture in the air and CO2 constituted, or a metal surface composed of many small primary batteries many weakly acidic, neutral dissolution, iron as the anode, electrons are lost oxidized to Fe2 +, the positive electrode the oxygen dissolved in water to obtain an electron is restored. Corrosion biological structure is made loose, not diffusion barrier profile metal ion etching process will be performed successively. Second, how to deal with chemical steam boiler sewage: sewage is also considered an indicator of boiler steam boiler, now say environmental protection, environmental protection sewage to be called within a certain range. Sewage discharge steam boiler to do less ground row row, that is, the number of sewage to be more, but the amount of each drainage control in a small area, both to ensure that does not affect the steam supply, but also make pot of water quality has been in control It is within specifications, and a large shake does not occur, which is very beneficial for boiler maintenance. Third, the chemical plant steam boiler protection and maintenance: 1, the burner should be every two months removed from the boiler, careful eradicate coke dust and other foreign matter. Photocell light-receiving surface scrub once a month, to keep the fuel filter and clean the filter function; carefully clean the filter inside the oil pump, not to damage the gasket. Not oil-burner idle, to avoid damage to the pump. 2, the protective boiler maintenance, it is necessary to cut off the power supply, it is necessary to relieve pressure. 3, pulling the safety valve once a day, to prevent rusting failure. 4, the water level gauge should always be kept clean, flush purge valve open once a day, to ensure water clarity. 5, when the boiler suspend the operation time is longer, should cut off the power, and do maintenance work: (1), dry maintenance, shutdown after the release came out water, dirt washed clean the furnace, slow fire the pot with a burner drying (combustion time not too long, to avoid damage to the boiler), and then after all the gas boiler drain, everything pipeline valves closed, to see once every three months. (2), wet maintenance for a period not exceed one month shutdown of the boiler, furnace shutdown after water release, discharge clean fill with water, cut off the power, close the valve. 4, the water level gauge should always be kept clean, rinse the purge valve is opened, the water level in order to ensure a clear day. 5, the boiler stops longer running time, cut off the power, and do maintenance work: (1), dry maintenance, shutdown after the release came out water, dirt clean the furnace, slow fire the pot with a burner after drying (burn time not too long, to avoid damage to the boiler), then drain all of the gas boiler, all pipe valve closed, checked every three months. (2), wet maintenance for a period not exceeding one month shutdown of the boiler, furnace shutdown after water release, discharge and clean fill with water, cut off the power, close the valve.

2 tons of diesel boiler has a boiler which is a kind of model diesel fuel boiler, such as the title of the diesel boiler 2 tons can be divided into 2 tons of diesel 2th fired steam boilers and hot water boilers 2 tons of diesel oil in accordance with its nature, generally 2 diesel steam boiler tons of little use, basically there are few places to use, because some of powered industrial steam boilers are for the most, so most buy two tons of diesel boilers for heating or for all customers hot, multi-fuel reserves sufficient for these areas of some refineries or oil exploration base, then the customer exactly how to choose the type 2 tons of diesel fuel boilers it? This chapter focuses on the next introduce to you: It is well-known oil-fired boiler factory in Henan square quick introduction, two tons of diesel boiler contains two main one is the WNS type one is SZS type, among which the best-selling type WNS, why, mainly because of the type of boiler small footprint, and high thermal efficiency, the waveform of the boiler furnace structure, increase the cycle so that the heat of the furnace off gas in value with a more abundant, and the boiler fuel savings, low price is now two tons of diesel boiler best-selling series. More questions about two tons of diesel boiler model and technical parameters please consult the online customer service!

The scaling of gas-fired 2th fired steam boiler not only reduces the thermal efficiency of the boiler, but also increases the temperature of the heating surface of the boiler, causes damage to the heating surface, and even causes the explosion accident of the boiler. Therefore, the use of soft water treatment equipment, strictly according to the process operation of boiler feed water softening treatment equipment, control boiler feed water quality, can delay the formation of the scale. At the same time, it is very important to control the boiler scale in real time, master the boiler scale and clean the scale if necessary. Because the temperature of the gas-steam boiler body and the steam-water heat pipe system is higher than the air temperature in the boiler room, some of the heat is emitted through radiation and convection into the surrounding air. This becomes a loss of heat. Boiler Therefore, the heat loss should be reduced when the heat insulation and heat pipe system of the boiler are damaged or leakage is discovered. The increase in noise from gas-fired steam boiler burners is mainly due to the closure of the valve or insufficient oil intake in the oil path, blockage of the oil filter, or because of low inlet temperature, high viscosity or oil on the pump. Too high temperature; oil pump failure; fan motor bearing damage; due to dirty turbine impeller, the equipment is too loud. This failure occurs when a gas-fired boiler is in use and is not easy to atomize (heavy oil) because of the high viscosity of the oil; it is also due to cyclone and jet The distance between the nozzles is inappropriate; in addition, because the burner is worn or dirty; it is also due to the excessive heating temperature of the spare fuel tank, resulting in steam pumping the oil pump out of the oil pump; or because the oil in the oil boiler is hydrated. Gas steam boiler feed water contains a variety of impurities and calcium, magnesium and other scaling substances, the boiler will inevitably expand. The thermal conductivity of the scale is very low, so once the surface is polluted by the hot surface, the exhaust temperature of the boiler will increase, and the heat loss of the exhaust gas will increase due to the increase of the thermal resistance. The experimental data show that the heat loss of waste gas will be increased by about 2%-4% when 1mm oxide is formed on the heating surface of boiler. The thicker the scale on the heating surface of the boiler, the greater the thermal resistance, and the lower the thermal efficiency of the boiler.

March 19, 2019, Tangshan, Hebei Province, the city government official held "2019 Tangshan depth control key industries scientific and technological achievements Matchmaking" meeting the cement industry on air pollution emissions caps mobilization discussion. According to the news conference, Tangshan City Cement companies need before the end of September this year will be dust, sulfur dioxide, nitrogen oxides are controlled to not more than 10mg / m³, 30mg / m³, 50mg / m³. Official documents will be introduced in the near future.

It is reported, as early as in September last year, Tangshan cement industry in particular has a value of air pollutants emissions of nitrogen oxides emission concentration is less than 50mg / m³ proposed.
