thermal efficiency 90 gasification hot water boiler
March 19, 2019, Tangshan, Hebei Province, the city government official held "2019 Tangshan depth control key industries scientific and technological achievements Matchmaking" meeting the cement industry on air pollution emissions caps mobilization discussion. According to the news conference, Tangshan City Cement companies need before the end of September this year will be dust, sulfur dioxide, nitrogen oxides are controlled to not more than 10mg / m³, 30mg / m³, 50mg / m³. Official documents will be introduced in the near future.
It is reported, as early as in September last year, Tangshan cement industry in particular has a value of air pollutants emissions of nitrogen oxides emission concentration is less than 50mg / m³ proposed.
September 3, 2018, Tangshan Municipal Government issued the "ecological environment in Tangshan depth remediation tackling month action plan", "plan" industrial enterprises in pollution control, discharge of pollutants in the cement industry to make the following requirements: single production of raw grinding material, bag filter employed; one mill kiln production process, humidification tower may be used - electric precipitator dust collection system, dust emission concentration ≤10mg / m³. Rotary kilns for cement kiln and, preferably high dust coating, conditioning tower may be used - electric precipitator, dust emission concentration ≤10mg / m3, the concentration of sulfur dioxide emissions ≤50mg / m3, nitrogen oxides emission concentration ≤ 50mg / m3.

Why more users choose to use the condensing steam boiler steam condensing boilers due its advanced technology, cost-effective, good quality and other advantages many corporate users to capture the hearts and minds, to stand out in a crowd kind of boiler, gradually became a public company recognized and selected mainstream boiler. Here we have to discuss about it, and why more users choose to use the steam condensing boilers. 1, equipment maintenance and overhaul convenient condensing steam boiler with automatic identification record set failure, which is not only for the convenience of users faster queries, can also help users to quickly identify the cause of failure in the boiler, perform maintenance and overhaul. Meanwhile, local boiler easy to damage also set up inspection holes manholes and hand holes, etc., once the site of failure, the operator through the inspection hole, will be able to carry out maintenance work, very simple and convenient. 2, intelligent operating system condensing steam boiler is through the intelligent touch-screen direct operation, intuitive operation can grasp the real-time status of the entire boiler, including the boiler flame height and temperature changes in the state, can glance. And all pre-condensation heating has a variety of programs that can be directly applied. 3, reasonable structure design condensing steam boilers science has been able to have good thermal effects, lasting supply of energy, because the main reason is that scientific rationality in the structural design of the boiler. For example an energy saving and a condenser at the rear, not only can help improve the efficiency of condensation of the steam boiler, and excellent selection of panel material great protection and thermal insulation performance of the sealing steam boiler using condensing process. Thus, the reason why users are keen to use the steam condensing boilers, the main reason is obvious, not only because of the full range of condensing steam boiler technology to improve the performance of outstanding features, energy saving and pollution-free and does occur in the use and supply sufficient heat, and on the repair and maintenance of the entire device is very convenient to be able to quickly deal with the problem by past record.
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.
