How to maintain the europe standard boiler shutdown? After boiler shutdown cooling, heating surface must be thoroughly cleaned of fouling and ash grate the upper, the lower portion of the furnace. Then to maintain a certain degree of natural ventilation flue. In general, in order desiccant moisture should be placed in the furnace, flue. The quicklime as a drying agent, within the furnace or flue gas per cubic meter should be placed generally about 3kg. After placing all the ventilation should be tightly closed doors. After the change of lime powder to be replaced. Low-lying position as boiler room, ground during shutdown severe flood tide, often approach should be used and placed a small fire to dry desiccant combination. How to care? If the boiler shutdown a long time, the boiler shutdown after complete removal of soot coated with an anti-corrosion red lead paint in oil or other metal surface furnace. As internal corrosion Maintenance shutdown of the boiler body, under normal circumstances, can be used wet shutdown maintenance is not more than one month, one month electrically operated steam boiler should be taken to dry more maintenance. To note the following problems when a dry maintenance: desiccant boiler not in direct contact with the metal surface, may be mounted in a container such as the iron plate after the desiccant is placed, and a hole for shutting the other hand hole cover.
Factors affecting the energy saving heating europe standard boilers What are the reasons 1, strictly control the temperature of the boiler exhaust gas boiler heating some of the heat loss, exha reduce flue gas heat loss is an effective way to achieve energy-saving heating boilers. There is a certain temperature difference between the outdoor air temperature and the exhaust gas temperature. When the outdoor air temperature is lower than the exhaust gas temperature, exhaust heat loss is generated. Accordingly, the heating boiler exhaust gas temperature should be strictly controlled within the controllable range. If the exhaust gas temperature is too high, if the exhaust gas temperature is too low may increa, it will lead directly to the heating boiler running cost increases, which is due to the increased tail heating surface, so that the exhaust gas temperature as low as possible. In the energy saving work boiler should be carried out technical accounting and economic accounting. Accounting based on the dew point of the smoke, the tail heating surface and heat loss due to the consumption of the metal. 2, the carbon content of the slag reduce heating boiler First, the operation of the heating boiler in order to ensure the heating boiler that burns coal, the coal particle size be controlled, full use of coal resources, while achieving the purpose of protecting the environment. Secondly, reasonably boiler operating parameters adjusted to reduce the carbon content of the slag, that the ratio of coal to air is more reasonable and the coal before combustion in the furnace. Furnace temperature is a key factor in the index reflects a lot of energy-saving operation of the boiler. The carbon content of slag is one of them. In order to ensure energy saving heating boilers, efforts should be made to reduce the carbon content in the slag, timely elimination of negative factors affecting the normal combustion boiler. 3, the outer surface of the boiler furnace control temperature of the boiler size of the heat affected second two factors is the temperature of the boiler outer wall. It is also important for the outer wall temperature of the boiler, the influence of the external surface temperature of the boiler heating boiler. Relatively larger exterior wall area, the higher the temperature of the external walls, the greater the amount of heat to the surrounding environment. To reduce the heat radiation loss of a boiler, the boiler must be controlled outer surface of the body temperature. 4, to improve the thermal efficiency of the thermal efficiency of the heating boiler heating boiler is a comprehensive index of energy-saving measures. Improve the thermal efficiency of heating boilers, but also help to improve energy efficiency and heating boilers. Improve operational level boiler operator, control of boiler operating conditions, timely maintenance heating boilers, heating boilers to save energy. 5, timely monitor the operation of heating boilers timely monitoring of the operation of heating boilers, not only improve the operational efficiency of the boiler, environmental protection can not be underestimated. Different boiler room should take different measures, timely monitoring of the operation of heating boilers. Spread the boiler room should be checked by installing equipment, computer monitor should focus boiler room.
Recently, the Government Office of Hebei Province issued the "Hebei province coal investment projects coal alternative management approach", mainly to strengthen air pollution control, the implementation of total coal consumption control target. The new "management approach" referred to new construction, renovation, expansion project of coal, coal should carry out the same amount of reduction or substitution (hereinafter referred to as a substitute for coal). Coal substitute coal should be completed before the project goes into operation.
These measures apply to administrative areas in Hebei coal for direct consumption of fixed asset investment projects. It refers to the direct consumption of coal raw coal, washed coal, other coal washing, coal slurry, coal, coal and other raw materials or fuels production and processing or combustion, its coal facilities (facilities, tools) including boilers, furnaces , gasification, blast furnace and so on.
Coal alternative pathway includes the following four aspects: the elimination of backward production capacity, excess capacity and Yajian enterprises closed down, converting reduce coal consumption; the implementation of central heating, reduce coal consumption saving technological transformation or removal of equipment out of coal-fired boilers and other equipment coal consumption; use of renewable energy, natural gas, electricity and other clean energy alternative to coal consumption; the other to meet the requirements of coal consumption reduction approach. Replacement of coal coal project supervision and management, energy conservation authorities responsible for co-ordination at all levels.
Coal to natural gas operations bunch of factors that vertical pressure steam europe standard boiler energy consumption indicators of the country are carried out in a big way, the choice of vertical steam boiler, to a large extent minus the pollution of powder, together with nitrogen oxides and other dangerous gases the press has been discharged. Energy consumption indicators is an important rule to measure vertical steam boiler, to discuss the next bunch of factors under pressure vertical steam boiler energy consumption indicators. By analyzing the relevant departments, vertical steam boiler heat loss occurs mainly includes two aspects: the proportion of non-standard sufficient combustion air with exhaust heat loss. Weaken the heat loss can be retrofitted in the vertical steam boiler chimney terminal latent heat of re-use form, or in the selection of better boiler system FGR. Combustion air ratio is not sufficiently decomposed inappropriate criteria: ordinary vertical ejector-type steam boiler burner based, air-fuel ratio can not be formed in the active mobilization. More vertical steam boiler based on a mechanical blower burner, air-fuel ratio due to the following standards several factors: air-fuel ratio standard comprises two situations: when oxygen is excessive, the excess will be an infinite cryogenic air by heat conduction, caused by rising energy vertical steam boilers, low energy consumption vertical steam boiler index; when there is insufficient oxygen, there will not be sufficient to ignite the situation, leading to low energy consumption indicators vertical steam boiler.
