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."
The purpose of the industrial boiler water treatment What are the specific purpose of industrial boiler water treatment has a specific purpose which boiler water treatment industry specific industrial boiler water which generally comes from groundwater or directly use tap water. Even if they look clean, but in fact contains a lot of impurities, boiler work easily lead to a lot of scale generated, affecting the thermal conductivity of the boiler, at the same time have a corrosive effect on metal structures of the boiler, boiler operation hazards. The main purpose of the timely processing of industrial boiler water is to reduce the harm of harmful impurities in the water or scale. The water quality has a direct impact on the work of the boiler. Fouling will result in thermally conductive boiler difference, steel contrast boilers, thermal conductivities only 1%, will seriously affect the thermal conductivity of the boiler, therefore, to raise the temperature of the boiler inner walls to protect evaporation, addition, it should increase blast volume boiler and the amount of coal feed, to enhance the exhaust heat consuming process, which can not be fully carbon coal combustion, combustion in the boiler will not significantly reduce the thermal efficiency. If the poor quality of the water will cause boiler corrosion, mainly in the following three aspects reflect: corrosion under the scale, oxygen corrosion and caustic embrittlement. Corrosion is mainly occurs in the inner walls of the boiler scale, iron ions contained in the water becomes high iron scale formation, leading to corrosion of the metal iron is accelerated under the scale, resulting in a new generation of scale, corrosion of iron finalized. In this regard, China has the exact requirements of the iron content in the water contained. Will result in poor quality or boiler fouling occurs Priming problems, and the main reason for the problem lies in the boiler water contains a lot of calcium and magnesium ions dissolved solids and other organic matter and fats, calcium and magnesium ions causing boiler fouling Effect heat transfer efficiency, while priming seriously contaminated steam. In addition, the water level gauge prone to bubbles, causing the water level does not display, automatic water level control system failure, resulting in a threat to the security of the entire boiler work. Therefore, handle the boiler water is very important, which affects the safety performance of boiler work.
Electric boiler heating process frequently why? 1. electric power boiler boilers electric power is too small is too small and the room is relatively large when it will result in an electrical boiler heating operation has been carried out, this case can not be met because the electric boiler heating the whole room, not reach the temperature needed to achieve it will frequently be heated, thus wasting energy. 2. The adjustment range when the temperature difference is too small gap between the set temperature and the high temperature is low will lead to a small electric boiler when heating operation has been performed, when the low temperature when the electric boiler is heated until the temperature reached to achieve the desired, then will slowly insulation, but if the temperature difference is set too low will make electric boiler has been in the heating, insulation, cooling, heating, insulation under the state, resulting in frequent power boiler start. 3. electric boiler thermostat thermostat problem is not able to accurately adjust the temperature can also cause electric boilers frequently start. 4. waterways clogged waterway blockage can cause electric boiler temperature fault occurs when frequent start because electric boiler water flow is very slow, resulting in instant reach the high temperature and then after a while the temperature will drop immediately, resulting in frequent power boiler startup problems. 5. The high-voltage electric boiler when the voltage instability will not work properly, so before using electric boilers must ensure the stability of the voltage, or the long-term use of electric boiler can cause damage to the equipment under voltage instability, voltage fluctuation range within ± 5% of the rated voltage between.
Energy conservation is a problem that needs to be considered in industrial production, especially for industrial boilers that support thermal power support for industrial production. Energy conservation is a reflection of the technical level of the boiler industry. With the implementation of the national energy conservation and environmental protection policies, the traditional coal-fired industrial boilers have gradually been replaced by natural gas steam boilers, and a revolution in energy-saving and environmental protection has taken place in the field of industrial thermal power.
Fire-tube boilers usually have a comparatively low rate of steam production, but high steam storage capacity. Fire-tube boilers mostly burn solid fuels, but are readily adaptable to those of the liquid or gas variety. Fire-tube boilers may also be referred to as "scotch-marine" or "marine" type boilers.Learn More
