shell fired boiler manufacturer

Heating and hot water shell fired boiler manufacturers 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.

Is shell fired boiler manufacturer thermal efficiency related to boiler load? The boiler thermal efficiency, according to its manufacturer Fangkuai boiler professional and technical personnel, its higher value is 85% of the boiler load, so, if the boiler load is 10 tons, and that load will exist for a long time. A boiler of about 12 tons should be chosen. And, when the boiler full-load steam supply, the boiler water supply will be increased.

Shandong Zhaoyuan Mining Group Co., Ltd. is a large state-owned local asset management companies, gold mining dressing and smelting for leading industries, operates in the area of ​​tourism, services, precious metals, real estate, eco-agriculture, with total assets of 10.2 billion yuan, Shanghai gold Exchange is an international provider of standard gold bullion. July 2017, Shandong Mining Group and fast shell fired boiler manufacturer steam signed a 0.5-ton electric heating steam boiler which mainly produce steam for metallurgical mineral processing and other manufacturing processes, energy defeating small, strong ability to supply steam .

Fourth, energy-saving effect

Now intelligent boiler equipment, modular design arrangement, the parallel combination of the simple, multi-joint control boiler. Users can produce according to demand, real-time adjustment of the number of operating boilers, to a great extent to meet the different techniques, different steam using steam differentiated, personalized requirements; comprehensive energy saving can reach 30%.
