energy saving boiler for chemical industry
Heating and hot water energy saving boiler for chemical industrys are mainly two uses hot water bath boiler fuel using steam turbine power conditioning subsystem - Frequency electrohydraulic control system similar to the feedforward - feedback cascade control system. Master regulator proportional regulator, the steam turbine power - frequency electro-hydraulic control system of a frequency corresponding to a difference amplifier which corresponds to droop ratio with the steam turbine, the size represents the size of the hot water boiler with a load capacity, proportional band the larger, the more hot water boiler with a load capacity; the sub-controller uses proportional-integral regulator, the steam turbine power - the power conditioner frequency electro-hydraulic control system corresponding to; the amount of fuel introduced into the feedback signal, and the steam turbine power - frequency turbine electrohydraulic control system incorporated in the pressure signal corresponding to a first stage, which is rapid elimination of the hot water boiler fuel quantity spontaneous disturbance. There are heating and hot water boiler bath for two purposes. Hot water boiler by circulating hot water circulation pump hot water holding tank, the tank hot water heating cycle can be achieved bath object; hot water boiler by circulating hot water circulation pump heating conduit, through the heat sink (radiator) people can achieve heating requirements; hot water boiler and hot water circulating pump with heat exchanger can be achieved bathing and heating dual function. Water speed before the hot water boiler should not start too fast, usually in winter no less than 4h, the other seasons 2 ~ 3h, especially in the beginning of the water should be slow. Hot water boiler water temperature is generally 50-90 ℃, so that the temperature difference between the feedwater entering the drum drum wall temperature is not more than 40 ℃. Not completely cooled gas hot water boiler, water temperature, mutatis mutandis, the drum wall temperature, or should slow down the speed of the water. When feed water enters the drum, the first wall half always in contact with the drum, when the feed water temperature and drum wall temperature difference is too large, the influent fast speed, upper and lower walls of the drum, the inner and outer wall will have a greater expansion difference, resulting in a large drum to additional stress, causing deformation of the drum, when severe cracks. Since the thick-walled drum, slow expansion, the wall of the tube is connected to the drum wall is thin, expanded rapidly. When the gas hot water boiler water temperature is too high or too fast, uneven expansion will cause the weld cracks, damage to the gas hot water boiler.
Finally, He Jinping, vice governor visited our laboratory cleaning energy saving boiler for chemical industrys, boiler shocked layout in the laboratory, the enterprise to acknowledge in-depth study of the safe operation of the boiler. Prior to departure, He Jinping, vice governor, said: "Your company is active in this research, visit the highest gold content of science and technology, value-added security strongest companies in the field of corporate research you safe operation of special equipment, has exceeded the government. the widespread perception boiler products. "
Condensing energy saving boiler for chemical industry using an advanced technology - condensation technique, it is provided inside the condensing heat recovery boiler, and absorbing the sensible heat released latent heat boiler, thereby improving the overall thermal efficiency of the boiler.
Popular Science: What premix condensing gas energy saving boiler for chemical industry, which are suitable for places: Nowadays, natural gas boiler generally begin to prevail in our country, whether it is industrial processes, heating or other production industries, natural gas boiler has a shadow.
