What are the advantages slip parameter Henan gas boiler unit? Henan gas boiler and turbine generator and start, while boosting boiler ignition, a low boiler parameters using superheated steam turbine to warm up increases the speed with load. Since the Turbo is warm start parameters steam temperature in the case of changing the vapor pressure and the like. Increases the speed. And a small amount of network and receiving the load, so called sliding start parameters, also called kit or unit is started. Many advantages: (1) start with the machine compared furnace separately, from the start to the unit with a full load, the time required is greatly reduced. Each turbine and boiler start-up time required, Henan gas boiler steam turbine start-up and the time required for the individual. And the time required for the steam turbine startup parameter sliding substantially equal to the time required for a single start, even shorter. (2) Since the parameters of the low initial start Henan gas boiler superheater outlet exhaust steam is used to warm recovered heat increases the speed and working fluid losses and part load, caused by exhaust. (3) warm the pipe warm lower pressure and temperature steam, thermal stress is much smaller than with the higher steam temperatures and pressures warm the pipe warm. (4) started separately, since the initial rise fire, the steam superheater is not cooled, burn-out to prevent overheating, you must limit the amount of fuel entering the gas boiler Henan. And slippery start parameter, starting with a vacuum in the condenser, soon there superheater steam cooling, Stokes speed can be significantly faster. At low pressure, large volume flow in the steam superheater, superheater tubes is not as small as the exhaust flow rate (about 15% to 20% of the rated evaporation), the flow rate variation when thermal image is generated individually activated deviation. (5) Sliding Parameters, Henan gas boiler starts to meet the requirements of the turbine increases the speed of the warm-up, because of the time needed to start a steam turbine is sufficient for the boiler. Adjusting the intensity of combustion boiler can be used (i.e., a control quantity of fuel into the furnace) to control starting conditions. When sliding pressure starting, due to the large volume flow of steam, it is advantageous to improve the water cycle and steam drum wall temperature difference from top to bottom.
Vacuum hot water boiler and cast iron boilers boiling temperature whether hot water boiler: A boiler for hot water boiler which, first of all to make some related issues, is as follows: vacuum hot water boiler this kind of boiler, its boiling temperature of water, What is? Cast iron boilers, hot water boilers which may be right? In addition, the three return, specifically refer to? These problems are on the boiler, so below, to explain in detail and answer, so that we have a complete understanding. 1. this kind of vacuum hot water boiler hot water boiler, the boiling temperature of its water, in general, how much is? This kind of vacuum hot water boiler hot water boiler, which usually work under negative pressure, so there is no danger of the expansion of the explosion, and compared with pressure hot water boiler, can greatly improve the safety of its use performance. Therefore, under a normal atmospheric pressure, a water boiling temperature is 100 degrees, and if it is at 6mmhg pressure is 4 degrees. 2. The transformation of the boiler, if it is transformed into hot water boiler, then, the internal structure of the boiler, external interfaces and systematic pipeline, whether should be carried out? The transformation of the boiler, if it is transformed into hot water boiler, then, the internal structure of the boiler, external interfaces and systematize pipeline, are to be involved, and are to be carried out, so, in order to have good transformation effect. And, if it is used for heating, then, preheat fast, but good results.
Note the use of the vacuum boiler: vacuum boiler at work because their internal pressure of the furnace is always in a vacuum, so the higher heat exchange rate and utilization. At the same time due to the unique design, so if the outside when the pressure exceeds atmospheric pressure in the course of the next, then the unit will automatically cut the power, and when there is a failure of the water level will alarm, so as to improve the professional vacuum boiler safety.
January 16, Harbin Municipal Environmental Protection Bureau Director of the atmosphere and noise pollution control at the public hall, Li Bin, said: "Harbin problem-oriented, focused on solving the coal pollution environmental air quality, autumn and winter of straw burning pollution." By a wide range of governance, 2018, Harbin has made in terms of ambient air quality improvement remarkable results, the standard number of days 310 days, an increase of 40 days, for the introduction of new environmental quality standards since the best of the year.
Prior to 2017, the total removal of Harbin urban built-up area of small boilers range of nearly 3,000. 2017, Harbin started the largest in the history of the elimination of small-scale boilers battle, tear down 9 district built-up areas and industrial parks within a small boiler 2074 units. 2018, further expanded the phase-out range, expanded from 9 Zone has outside built-up areas, where the built-up area in District 9 out of 10 tons of steam per hour of coal-fired boilers to achieve foundation "clear" on the hour and eliminated more than 10 tons of steam coal-fired boilers 99 units, out of the city a total of 1191 units. The results accumulated over the years, significantly reducing the use of coal, reduce emissions of pollutants.
According to reports, in the fall and winter seasons, Harbin straw Jinshao pay close attention to the work to implement the five grids responsibility, building straw Jinshao 24-hour duty system inspections, inspection teams at all levels of uninterrupted inspection. In addition, Harbin has also implemented emission standards of air pollutants, vehicle control, open-air barbecue ban, dust management, especially in heavy weather pollution contingency timely warning, take active control measures played a role in the down-clipping. Through various management, air quality has been greatly improved.
