How to siting the boiler room to install gas hot water boiler? When the gas boiler selection, will consider various factors, then a reasonable selection; but often do not notice the choice of location of the boiler room, in fact, the position of the boiler room will be related to the pre-investment costs, late operational management and security work, etc., is a rather important aspect. So how should be address to choose? (1) Gas boiler room so as not to set off in a crowded place too close to the area, in order to avoid noise in the boiler during operation or have other unforeseen circumstances affect human life and safety. (2) boiler room in most cases will be subject to various conditions, to be located in the basement of high-rise buildings and other places, then you should seek the consent of the relevant departments in advance, but it should also be noted that the choice of fuel and boiler rated evaporation and vapor pressure criteria defined in this state. (3) the location of the boiler room during the selection should be also taken into account the type of building, in the form of the system, operating pressures and other factors, to set up or normal operation of other facilities for the latter part of the pipeline, to lay a prerequisite. (4) should be close to the boiler room where the heat load more concentrated, in the tube grid, rational arrangement of the heat pipes to ensure economical and convenient. (5) in favor of natural ventilation and lighting, it should not be too confined space. In short boiler room location, taking into account the legitimate economic factors facilitate the safe operation of boiler standards, local conditions, etc., must not be selected without any planning, to the disadvantage of post-maintenance.
The reason condensing gas boiler fouling fouling What is the boiler is condensing gas boiler maintenance and repair should focus on issues, not only because fouling threat to the safe operation of the boiler, but also greatly increase the cost of maintenance and repair boilers, boiler shortening life. For boiler fouling problems, we should be in-depth analysis of its causes, promptly take effective preventive measures to provide effective protection for the safety, energy conservation, economic operation of the boiler. (1) a carbonate, sulfate scale carbonates, sulfates reasons of scale formation due to condensation gas boiler is the presence of calcium, magnesium, carbonates, sulfates, etc. to the solubility in water decreases with increasing temperature, to a certain extent will precipitate scale. Carbonate scale, is generally formed in the heated places less intense; sulfate scale precipitation is generally at a high temperature, often occurs in the heating surface heated relatively strong, and it is in the waterwall tubes of the boiler convective tube bank common. (2) Chemical composition of silicate scale mainly aluminum silicate scale, iron silicate compound, the chemical structure is more complex, this scale hardest texture, and very poor thermal conductivity, so the maximum harm, in general forming a high thermal condensing gas boiler load tubes. (3) the main component is iron scale iron oxide scale iron compound, condensing gas boiler in normal operation, the oxygen content of the water is very low, oxygen does not cause corrosion of the boiler. However, if the increase in dissolved oxygen, can lead to corrosion of metal surface oxide, iron oxide generated in the boiler product was dissolved in water, and at high temperature, the iron oxide scale formed gradually. For scaling condensing gas boiler safe and economic operation of harm it is very large, because it's hidden features, easily overlooked, but the boiler accidents caused due to scale accounts for a large proportion. Only by understanding the reasons for fouling produced, find a solution, by taking appropriate measures to avoid fouling, in order to ensure that the boiler safe fundamentally, run the economy.
Recently, the district government Qingyang City, Gansu Province, deputy head of Xifeng Wang Chao organized a remediation coal-fired boilers will promote the work. By the township (street), the head of district straight relevant departments attended the meeting.
Written meeting issued atmospheric district office "notice Leading Group Office of Air Pollution Prevention
Wang Chao requires that all relevant units must concentrate efforts to promote coal-fired boiler renovation, remediation to the control list, in strict accordance with the "three three must" requirements, to promote catch, this area, this system is not in place of coal industry regulation boiler immediately carry out concentration and control, to ensure that the work complete, fully put in place. To collaborate actively cooperate with the township (street) mainly clear time limit for rectification and reform measures, solid progress. To strictly control inventory and remediation remediation standards of accountability and strengthen supervision of the ideological hesitation wait and see, action is delayed, focus on promoting renovation is not complete unit, accountability seriously investigated.
In operation gas steam boiler water may not be anhydrous or combustion, the boiler at this time may be in the dry state. When a user finds a boiler in such a situation, the user should be vigilant, timely and secure processing, in order to make the boiler to avoid irreversible serious accident.
1, if found severe dry gas and steam boiler, should immediately stop heating was continued until the temperature of the boiler was cooled, identify the reasons for troubleshooting. Ventured must not add water to prevent the occurrence of cracking furnace of strike.
2, boiler operator must have proficient skills, master the performance of the gas steam boiler, procedures and processes, to prevent illegal operations.
3, if the shutdown in the winter, you must put the net boiler water, prevent frost damage to the boiler situation. During the summer without a boiler, furnace water also should put the net, use dry lime maintenance.
4, if found steam boiler furnace gas pumping force reduction, it is necessary to do cleaning treatment furnace, the furnace door, or in the neck of the chimney with a rubber hose running water rinsed.
