In the fierce competition in the market, fast dealer boiler commercial moldavia adhere to "not forget the early heart, sustained ingenuity" of the faith, taking the long view, establish and improve a comprehensive overall solution, leading to control market trends, improve the environmental performance of the boiler, make unremitting efforts to build China clean boiler brand.
Boiler installation of "blast doors," What is the role now on the market most of the dealer boiler commercial moldavias to gas, oil, biomass, electricity as the main fuel, coal-fired boilers because of its harmful pollution levels gradually been changed or replaced. In general, no boiler explosion during normal operation, but if it is due to the improper operation of the ignition or operation, it may cause the furnace or tail or secondary combustion flue explosion, resulting in serious danger of impact. In this case the role of "explosion vent" is manifested when the furnace or flue trace knocking occurs, the pressure within the furnace is gradually increased, when a certain value is higher than the pressure relief device can turn on itself through the explosion vent to avoid the risk expansion to ensure the overall safety of boiler and furnace wall, more importantly, it is to protect the safety of the boiler operator. Currently there are blasting boiler membrane and two kinds of swing-proof door. Swing-proof doors are mostly placed in the furnace wall of the combustion chamber. Their installation position can be divided into vertical and tilting, by the door frame, the door and the hinge member and the like components. The door frame and multi-cast iron round or square, the width of their mutual contact surface generally is 3 ~ 5mm, and to ensure seamless tight. The door is coated with a heat-resistant concrete, which limit the pressure according to a desired thickness value has been calculated or determined experimentally. When the gas in the furnace or flue explosion, the door is automatically turned about the shaft relief, and then shuts itself down. Sealing pressure of the vent door from the inclination angle (usually not more than 30 °) or the downward pressure created by the weight of a weight is obtained. Most membrane blasting explosion vent means on the flue, and a clamping device consisting of explosive membrane. Bursting disc is typically made of a thin metal plate of asbestos, aluminum and stainless steel. When an explosion occurs in the furnace or flue gas generated shock wave pressure to bursting membrane damage, play the role of relief, once the explosion vent membrane after blasting effect, it will not reset itself, the clamping device must be open blasting repositioned membrane. Note 1, the position of general device explosion-proof door on the wall or on top of a steam boiler furnace furnace exit side of the furnace flue fuel gas. 2, explosion-proof doors should be installed in place without the threat of operator safety, and a pressure relief guide tube, it shall not be stored near inflammable and explosive materials, highly preferably not less than 2 meters. 3, activity blast doors require regular manual test to rust dead.
Selection and classification of fuel gas thermal control system fuel gas dealer boiler commercial moldavia 1. The boiler classification thermal control system (1) electric system for an electric meter instrument cluster system consists of relays, time relays, the relay program composed of program control and interlock system; manufactured by electronic control and intelligent series or digital instruments, measuring instruments display, sound and light alarm monitoring instrumentation and control system and other components. Electric instrumentation system design experience mature, the price is cheap, but it is difficult to achieve system redundancy, remote data transmission, maintenance is more difficult, more difficult to implement advanced control methods. Electric meter system is mainly used for small boilers, but the electronic control Applications for closed-loop regulation of decreasing almost been replaced by intelligent multi-function instrument, the following sections mentioned electronic control just want to take advantage of familiar industry and the series combination of a widely used instrument that time to explain the principles of the control system configuration and (2) programmable control system programmable control system is the core of programmable logic controller (PLC). Programmable logic controllers are widely used in the initial control, since the 1990s has increased the ability of process control, the programmable logic controller in the field of process control applications more widely.
Different meaning of the data and the oxygen content of the exhaust gas fired dealer boiler commercial moldavia: A boiler oil-fired boiler which, it is explained below target, because through knowledge and understanding of this kind of boiler, can broaden everyone's knowledge, and at the same time, familiar with the different boiler type, so as to achieve a comprehensive understanding of the boiler, do not miss any of which. 1. fuel boiler, 0.5 tons and 0.35mw, its meaning is the same as you? An oil boiler, and 0.5 tons 0.35mw these two parameters, which specifically refers to, and is not the same, because the former is the rated evaporation of the boiler, while the latter refers to the rated power of the boiler or the rated for heat. In addition, in the unit, the two are not the same. So, obviously, on this issue, that the answer is not the same. 2. Industrial boilers, oil-fired boiler is why the general level? In addition, the oxygen content in the exhaust gas boiler fuel, how much is more appropriate? Industrial boilers, if its use is oil-fired boiler, then, it generally is a Class B boiler, that is, the pressure of the boiler is rated at 2.5MPa or less. Oil-fired boiler exhaust gas oxygen content and, in general, is controlled within the range of 3% to 5% is appropriate. If less than 3%, the problem of incomplete combustion occurs.
