Matters pressure hot water boiler system cost use to note what pressure hot water boiler is the device of choice for many heating boiler units, its high safety indicators. The main reason for the boiler has a top vent, furnace pressure consistently with the outside atmospheric pressure, normal use will not harm the explosion occurred. However, some users do not have to fully understand the atmospheric hot water boiler, tend to ignore the many precautions, leading to accidents in the actual operation of the boiler. Here are some questions fast boiler arranged atmospheric pressure hot water boiler in the safe use should be avoided, and I hope for your help. 1, when the atmospheric pressure by some users will directly use the water closed loop boiler or heating system, boiler atmospheric exhaust pipe and a return pipe considered, it may be easier for users, but this time the boiler full water pressure in a very dangerous state. This loop has two hazards: First, when the boiler water temperature is too high, the steam produced can not be discharged from the furnace, the pressure in the furnace continues to rise, explosions and spills may occur at any time. 2, pressure hot water boilers into steam boilers some users to atmospheric steam boiler hot water boiler, the exhaust pipe is directly mounted on the boiler, a control valve mounted on the exhaust pipe, some users will be a control valve mounted on the exhaust pipe, installed directly from the boiler hot water bath with boiling water or a control valve, which is why the boiler operation unsafe. If you close the control valve in the boiler operation, in the case of increasing pressure, ordinary pressure hot water boiler is prone to explosion, the consequences are very serious. 3, the rapid development of product quality varied atmospheres of hot water boiler manufacturing and gradually led to an oversupply of the market, resulting in some factory price positioning of the distress is not good, some manufacturers technical weakness, poor manufacturing quality, even cut corners. Use of the boiler had a negative impact. Design, manufacture, installation and operational atmospheric hot water boiler is safe and reliable factors affecting boiler. In order to stabilize atmospheric hot water boiler running on the user site security, we should pay attention to the following questions. (1) design and manufacture of boiler pressure hot water boiler departments should conduct in-depth research. The combustion, heat transfer, air and flue gas flow, hydrodynamic properties, adapted to the design of the boiler pressure and atmospheric pressure operation of the heating system. Ensure atmospheric pressure hot water boiler can maintain atmospheric pressure or slightly under any circumstances; (2) R & D and boiler characteristics adapted to a stable and reliable control system, pressure hot water boiler heating system to ensure safe and reliable operation; (3) establish boiler management systems, training furnace workers, avoiding major accidents due to the low level of operation and improper operation caused.

Paper industry coverage is very wide, the user in the choice of a steam boiler, require a combination of local environmental policy as well as the actual operating cost analysis, select the appropriate boiler selection.

Steam Boiler explosion: the production of steam boilers and hot water equipment, because it can provide power and heat. With the development of production, boiler equipment increasingly widely used in various sectors of modern industry, one of the important thermal equipment development of the national economy [1]. Industrial boilers is both common equipment, special equipment is potentially explosive. Boiler during normal operation, the system stores a lot of heat, it not only to withstand the high temperature and pressure, but also to withstand the media and fly ash erosion wear, the work environment is bad. Once some of the reasons why accidental release of stored energy, it will cause property damage and even loss of life. In recent years, our boiler explosion accident occurred frequently, to economic construction and social civilization has brought a greater impact [2]. Through scientific and objective means of detection, after the explosion of steam boilers were analyzed comprehensively and systematically, to find out the root cause of the explosion, the provision of technical ideas for future failure analysis of steam boilers.
