Third, do not use over-pressure boiler
Since the pressure of the boiler can withstand pressure in the boiler has been used previously to determine a good through precise calculation, it is not freely beyond a predetermined pressure range. Because the thickness of the steel and testing requirements of different pressure boiler used is not the same, if not in strict accordance with the provisions of excess pressure boiler will result in unbearable pressure boiler explosion.
Boiler coking coking hazards caused great harm to the boiler operation and safety will mainly be reflected in what areas? Today small for everyone to specifically introduce: 1, large focal block after the boiler fell, instantly generate a large amount of steam, so that a large number of cool air leakage into the bottom, causing the burner region (especially lower stage burner region) pulverized coal flame serious deterioration of the situation of fire, so that negative pressure generating furnace volatility (overrun) caused by boiler fire; coking time if the fused bulk, fall by gravity from the upper portion, resulting in water wall smashed cool ash, resulting in even down load shutdown; 2, when all the water wall coke, only manual shutdown decoking; 3, furnace coking temperature rise caused by superheated steam, resulting in superheated steam temperature and reheat steam temperature desuperheating water to open a large, or even lead pipe soda blasting; coke boiler output will reduce, causing severe forced shutdown; 4, will shorten the life of the boiler coking equipment; exhaust loss increases, reduce boiler efficiency; 5 increase, induced draft fan power consumption. And that knowledge about the dangers of boiler coking, I believe you must have a lot of harvest it, I hope this can help you to better avoid the occurrence of such phenomena.
Boiler inspection and external examination order and the Boilermakers difference fireman: boiler products and keywords the site, because it is important and flagship product, the site box boiler, so the learning attitude, and careful attention should be paid treat, not sloppy. And here, we will, be carried out by a number of specific issues of their study and work, and give their corresponding answers, so that we can based on the original, to further deepening and expansion. 1. boiler, which is the first inspection within or outside the check? From a professional point of view, in the boiler should be seized, and then is external examination. Also, if you find a problem in the internal examination, then, is to wait until after the external inspection, if there are problems be dealt with. In addition, in the test cycle, in general, is conducted annually external inspection, internal inspection once every two years. If the same year, both internal and external inspection should be carried out, then, is outside the inside first. 2. Vertical shell boiler, which has its specific species? Vertical shell boiler, which is a boiler, in which specific species, there is a transverse vertical water tube boiler, water tube boiler vertical multi-lateral, vertical straight water tube boiler, water tube boiler vertical bending, and Li type fire-tube boilers and other such. However, for now, the latter three, is the straight vertical water-tube boilers, water tube boilers of vertical bending and vertical fire tube boiler, is using three more.
Hot water boiler is the essential equipment of our hotel, one of the parties to provide fast condensing pressure hot water boiler immediate operational effect. Our demand for environmentally friendly and out of the hotel itself, very high environmental performance requirements for boilers, party fast products fully meet our needs, the index after testing are in line with the relevant provisions of the State; with the outside atmospheric pressure remains stable sufficiently improved security index boiler, eliminating our worries. --customer feedback
