After a long process of evaluating all types of efficient brown coal hot water dzl boiler systems available - including heat pump, gas, oil, coal, wood, biomass etc - a couple of years ago I installed a brand new biomass boiler system in a large country school in Poland. Each system has pros and cons - for instance, convenience versus fuel costs, and so on.sAs it was a big project to run new pipework and fit new radiators throughout the whole house, as well as a new boiler, hot water storage tank and controls, installation costs were a big factor in the decision making. Also, I wanted the lowest long-term running and maintenance costs. It was also important that the biomass heater function during power cuts.
Recently, many users of the phone does not know how to shutdown after the steam efficient brown coal hot water dzl boiler maintenance, boiler maintenance is very simple in fact, today we explain the steam boiler and hot water boiler shutdown after: After the steam boiler maintenance shutdown method how maintenance. Since the cause of boiler failure or power shutdown required boiler, a steam boiler before travel should stop combustion boiler, the boiler slowly lowering the temperature until no pressure boiler, should pump before shutdown, induced draft fan and turn off the blower. After the maintenance shutdown home for boiler, furnace divided into external corrosion and home for the pot. Pot corrosion enjoying, enjoying their home for two kinds of wet and dry selected based on the length of shutdown time. When long-term disabled boiler, furnace should be paid close attention to external corrosion problems take care of themselves. First, the boiler shutdown cooling is necessary as far as possible completely eliminate fouling and ash grate heating surface of the upper, the lower portion of the furnace. Then have to adhere to certain natural ventilation flue. Under normal conditions, should be placed to dry moisture-proof agent in the furnace, flue. The dry quicklime as used, the furnace or the flue gas per cubic meter of ordinary should be placed about 3kg. After placing all the ventilation should be tightly closed doors. Lime powder to change after change. Such as boiler rooms in low-lying position, the air during shutdown severe flood tide, the method should be used regularly and placed a small fire to dry dry agent phase separation. If the boiler boiler long time, in order to thoroughly clean the soot topcoat red lead oil furnace or other metal surfaces in the anti-corrosion paint. As for the way home for corrosion inside the furnace shutdown, the shutdown Yaoan the length of time to be. Under normal circumstances, no more than one month shutdown of the available wet home for a month or more should take care of themselves dry. Dry to pay attention when enjoying the following questions: Do not dry agent in direct contact with the metal outer boiler, can be housed in a container such as an iron plate; dry agent after standing, for shutting the hole and the other hand hole cover, the vapor, the water pipe necessary to cut off valve; variant lime powder should be replaced. While enjoying wet, to pay attention to boiler water condensate is preferably used, followed by the available existing boiler water, demineralized water again; after adding the base, with a slow fire boiler water is heated to 80 [deg.] C to 100 the pressure rose to 0.2 maintenance after 0.3MPa 2 to 3 hours, so that it reaches the furnace circulating water alkalinity balance, pressure is reduced, then fill the boiler water, a certain gauge, and continue to adhere to this pressure throughout the home for alkalinity should be regularly tests, decreases should be added at any time; in winter, wet enjoying pay attention to antifreeze, especially the local sewage channel and economizer; before re-use should release all the pot boiler lye, best prepared sump, in order to facilitate further use. At the same time should be rinsed with clean water. The performance characteristics of coal, oil, gas steam boiler
WNS What are the advantages of gas condensing efficient brown coal hot water dzl boiler with the country's commitment to increasing air pollution control throughout the country have introduced corresponding policy, enacted almost everywhere timing and amount of boiler. In order to save operating costs, most enterprises in the transformation process of the boiler will choose a coal-fired boiler is a condensing gas boiler. So, we need to WNS What are the advantages of a gas condensing boiler detailed understanding. WNS gas condensing boilers What are the advantages of air pollution coefficient small traditional coal-fired boiler during operation will generate a lot of smoke pollution, which is extremely detrimental to the environment, but high-quality gas condensing boiler has to gas as a power source, replacing the traditional coal-fired way. Therefore, there is no coal pollution during operation, which is not only important for environmental protection, but also can reduce harmful gas emission purification device configuration, thus reducing operating costs. Higher safety coefficient due to condensation gas boiler advanced structural design and build these boiler systems have a variety of protective functions of protection, the system comprising high and low voltage protection against dry protection, overheating protection and to prevent leakage protection boiler, by function, the process of condensing gas boiler operation can effectively reduce the potential security risks because of negligence. Small high high-efficiency heat loss condensing gas boiler generated steam can be recovered, not only better water recycling, waste heat can be effectively collected. Meanwhile, the condensing gas boiler advanced temperature control, the internal heat loss of the entire boiler system small, more efficient energy utilization. Therefore, it is possible for enterprises to save a lot of electricity, water and fuel.
