Whether shutdown any case, we must maintain timely contact with steam departments.
Meaning high-pressure pumps and electric boilers and boiler relations eye: boilers and high pressure pumps, What is the relationship between them? Circulating fluidized bed boiler, its coal particle size furnace, whether there requirements? And, on the boiler, which related issues, it is we do not know? These are the boiler on the product website, so the following will explain and answer, so that we have the right ideas, and know how to properly answer. 1. between the high pressure water pump and boiler, what is the relationship? High pressure water pump, its main role is to extract fresh water from a water storage tank, and then into the boiler, thus, supplemental water boiler work. Therefore, it is generally used in conjunction with the boiler. However, due to the high pressure boiler operation process, therefore, it requires high pressure pumps have a powerful driving force, in order to form a high pressure, to ensure that the work can be carried out smoothly. Further, on compression performance, but also has certain requirements.
Why supervisory inspection-free steam boiler steam boiler characteristics can exempt? According to the "Steam Boiler Safety Technology Supervisory Regulations" provides that the normal water level of boiler water volume less than 30L in the boiler does not belong to the scope of the surveillance. When the normal water level of boiler steam boiler water volume is only 27L, like installing a home water heater as safe. So steam boilers belong to exempt boilers. You can avoid the security of small steam boiler What are the benefits? 1, you can not build a separate boiler room, can be placed in the basement, roof and other places 2, do not have a full-time duty Boilermakers (conventional boiler requires certified fireman) 3, eliminating the need for a year dealing with government departments, burning more peace of mind coal steam boiler What are the advantages over conventional steam boiler? Coal-fired steam boiler, is lower than conventional coal-fired steam boiler safety running costs, fast start, no registration and annual inspection, firing five minutes produce steam. Coal-fired steam boilers suitable for use in what place? It can be used in hotels, factories, hospitals and other occasions.
