Safe use of chemical plant 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.

What type steam boiler is? Electric heating boiler and the boiler is mainly composed of electric control box and control system. Its characteristics are environmentally friendly, clean, no pollution, no noise, automatic, with limited energy and reduce prices significantly, as a new boiler electric heating boiler equipment increasingly being recognized. Electric heating the core member is electrically heated boiler, directly determines the life of the boiler, to select a non-metallic electrical heating tube (such as a ceramic heating pipe), because it is resistant to the load, a long life, and a water separation structure, the boiler Wing no leakage. Press working medium can be divided into natural circulation boiler, forced circulation boiler, boiler DC. Biomass boiler is a kind of boiler to biomass energy as a boiler fuel called biomass boilers, steam boilers into biomass, biomass 13 ton portable hot water boiler, biomass stove, biomass thermal oil heaters, vertical raw biomass boilers, biomass boilers and other horizontal. 2, according to the water-tube boiler flue gas flow, boiler shell (fire tube boiler), water - Combined fire tube boiler. 3. Press installation fast loading boiler, boiler assembly, bulk boilers. 4. Place the vertical and horizontal boiler boiler according to the boiler drum. 5. End-use domestic boilers, industrial boilers, utility boilers, marine boilers and motor. 6. Press media steam boilers, hot water boilers, soda boilers, organic heat carrier boiler. Natural circulation water circulation, forced circulation and once-through boiler, combined cycle. 8. atmospheric pressure boilers, low boilers, medium pressure, high pressure boiler, high pressure boiler. 9, the internal combustion boiler combustion, external combustion boilers. 10, coal-fired boilers, oil-fired boiler, gas-fired boiler, pulverized coal boiler, waste heat boiler, electric heating boilers, biomass boilers. Many types of steam boilers, the key is what kind of needs, because different categories, so in different places, use different steam boiler. In order to ensure better use.
The fuel oil of the oil-fired boiler is injected into the furnace by the incinerator and shows fog-like oil droplets, which is easy to mix with the air and burn rapidly and exotherms rapidly. Compared with the coal-fired boiler with the same parameters and capacity, the thermal strength of the furnace volume can be doubled to 1046.6 × 10 kilo coke / m / m ·h. However, in order to reduce the heat load in the incinerator area and avoid the overtemperature of the water wall tube in this area, the furnace volume is only reduced by about 1 / 3. Because the ash content in fuel oil is very little, it does not form slag on the convection heating surface, so the flue gas temperature of furnace outlet can be up to 1300 ℃, and the pitch between tubes of convection heating surface can be reduced to improve the flow rate of flue gas. Then the heat transfer coefficient of the heating surface can be improved and the heating area and steel can be saved.
