heavy oil fired steam boiler food industries
Pressure fuel boilers interpretation of the overall daily operation and maintenance of oil-fired boilers with atmospheric corrosion knowledge structure, including boiler and auxiliary equipment of two parts. Boiler furnace, drum, burner, water wall superheater, economizer, air preheater, and the furnace wall, etc. The main frame member constituting the core part of the steam production, called boiler. Boiler body is in two main parts and drum furnace. Also known as the furnace combustion chamber, fuel combustion for space. The solid fuel on to the grate, referred to as a fire bed combustion furnace Stoker, also known as fire bed furnace; solid fuel furnace liquid, gas or pulverized, is injected into the combustion chamber is called the fire chamber burner, also known as the furnace fire chamber; air coal particles burn hold it was boiling, and the furnace is inferior fuel suitable for combustion is called fluidized bed furnace, also called fluidized bed furnace; coal particles so that an air flow rotated at high speed, and strongly called fire cylindrical cyclone furnace hearth. Boiler pressure fuel daily operation and maintenance link and chemical corrosion, turbine attendant prepare enough desalinated water, oxygen, water passing temperature no higher than the drum wall temperature 50 ℃; Sheung during hot drum wall temperature should be after the temperature of the metal is not more than 40 ℃ before a new installation or repair departments boiler Feed records an indication of expansion. Sheung summer time less than 2 hours, at least 4 hours in winter, when the temperature and Sheung drum wall temperature difference of less than 40 how ℃ boiler reheater corrosion protection? after turbine fight gate, boiler guarantee a blower, an induced draft fan is running the best cross retain two oil gun. turn reheaters to the empty exhaust steam reheater hydrophobic doors and air doors corrosion, anti-corrosion of the reheater steam temperature is lower than a predetermined deg.] C for 400 control drum water level within an allowable range. anticorrosive time less than 20 minutes after stopping two oil gun operation. guarantee furnace pressure when 50--100Pa, each of the flaps open, baffle for ventilation less than 5 minutes, stop sending, fan, each of the flaps closed tailgate may be appropriate to accelerate Sheung speed.
How to combine gas fired steam boiler food industries when a parallel gas steam boiler / steam boiler two or more than two runs, the new operational boiler steam supplied to the total charge of steam, the furnace is called parallel, how a natural gas steam boiler is operating analysis of: (1) steam boiler gas before the merger, should decrease the fire. Gas-fired steam boiler burner underlying mode, two-pass configuration, the fuel combustion, the boiler operation is stable and take up less space, while the spoiler is inserted smoke tube, smoke slow speed, increase heat transfer, a high thermal efficiency, reducing the total cost of the user is provided drain pipe, the water shall be discharged, and then washing water level gauge, the normal water level is maintained below the water line. (2) At this time, the steam pressure gas steam boiler is reduced, when the steam pressure is below the vapor piping system pressure of about 0.05MPa, the water level can be in communication with the furnace. Biomass boiler categories: biomass boilers Horizontal, vertical biomass boilers. Biomass gas thermal oil heaters, biomass steam boiler, biomass hot water boiler, biomass oil furnace. (3) a combination of steam gas boiler, a main steam valve should be opened slowly. When the main steam pipe soda no impact should open the main steam valve, to observe changes in water level. (4) Complex fire, pay attention to the steam boiler water, maintain the normal operation. Gas-fired steam boiler burner underlying mode, two-pass configuration, the fuel combustion, the boiler operation is stable and take up less space, while the spoiler is inserted smoke tube, smoke slow speed, increase heat transfer, a high thermal efficiency, reducing user fees gas steam boiler drum double lateral structure, completely overcome the bulging phenomenon boiler superheater tubes are directly exposed to the furnace caused by the heating surface is disposed more reasonable. Using membrane wall structure on both sides of the furnace, both to ensure the sealing of the furnace, but also improves the thermal efficiency of the boiler.
How to deal with water shortage in electric fired steam boiler food industries machine in use for some time this or that problem will be serious delays in the progress of work, causing great inconvenience to the people, such as water shortage, this problem arises in the use of electric steam boilers after a period of water shortage in how people deal with how to solve it. Electric steam boiler how to deal with water shortages: water level proofread each water level indicated by the right to judge whether the electric steam boiler water. In the electric boiler can not be determined when full of water or water vapor, can turn on the water faucet open water level, water flows out of the pot if not, indicating that water scarcity is an accident, otherwise it is full of water accidents. For the embodiment allows a small electric steam boiler waters operation, water may be called first, determines the electric steam boiler is mild or severe water shortage. This only applies to the water level gauge water hole communicating tube heating surface is higher than the highest water capacity and fire community large electric steam boiler. Otherwise it can not be called electric steam boiler water, because it will delay the time of the incident electric steam boiler water treatment, the worsening of the situation. When a slight electric steam boiler water, should reduce the fuel and air, the combustion decreased, and electric steam boiler feed water slowly to the normal level. Typically by adjusting a valve opening degree and the size, to control water flow rate and water, being careful not excess water. To quickly identify the cause of water shortage in the water and remove the process, and then check the electric steam boilers there is no unusual circumstances, after confirmation by the normal operation can resume electric steam boilers. When electric steam boilers severe water shortages, the need for emergency fire fighting shutdown. The fire shutdown procedures according to the method of implementation of the emergency shutdown, is strictly prohibited water to the pot and when serious water shortages. Some fireman personnel after the discovery of electric steam boiler water shortages, interrupted several times with water, each time a small amount of water replenishment way to cover up the accident electric steam boilers. This practice is very dangerous. If electric steam boilers are also less severe water shortage will cause biomass boiler leaks. If electric steam boiler water can cause serious electric steam boiler explosion. Only natural ventilation and cooling in electric steam boiler pot temperature dropped to below 70 ℃, water only slowly. Electric steam boiler for the water to normal level after thorough examination, no abnormal situation in order to re-start ignition, electric steam boilers to resume operation. Traditional old-fashioned coal-fired boiler using coal, gas, fuel oil and other fuel, these fuels are non-reusable primary energy, the future price will be higher. And the shortcomings of the traditional old-fashioned coal-fired heating methods are also caused by incomplete combustion, incomplete combustion can cause a lot of heat from the flue gas discharge out together, so it will cause energy losses. Boiler not only save electricity, but also saves time and effort, not the traditional coal-fired boiler heating boiler released by carbon dioxide, toxic gases, dust and other harmful substances, so users do not need to clean up, so it can save a large sum of maintenance cost.
Car accessories types of complex processing, such as the interior wall Peng, floor, seats, instrument panels, sound systems, many processes required in a high temperature environment, the temperature becomes optional metrics wind Visteon hot water boiler. It is reported that Dongfeng Visteon existing boiler equipment can not reach the growing production needs, the introduction of fast boiler production of two parties often piezoelectric hot water boiler (CWDR1.8-95 / 70-II) in 2017.
