different types of steam boiler

Gas leak occurred boiler gas boiler gas leakage - small different types of steam boiler manufacturers tell you how to do it. Gas boiler leak accident occurred in the use of how to do, let's look at the causes and emergency measures leak accident: 1, gas boiler leaks must be stopped in time, press the emergency stop button is pressed. Second, the main gas valve to close the boiler, cut off the gas supply, then processed according to their specific leakage. 2, the burner leaks: the main valve must be closed immediately boiler, timely reporting to company safety departments, develop detailed contingency plans based on leaks of gas boilers, and find the appropriate technical personnel. 3, indoor gas pipeline leak: shutdown immediate needs, but also turn off the main gas valve boiler room, then promptly told the gas company and its safety and production departments reporting can occur based on a series of gas-fired boiler leak emergency treatment.

China Dunhuang International Hotel relevant responsible person said, party fast or aftermarket both in pre-sales, remained consistent patient service, we have solved many difficult problems, with fast boiler, we are assured. --customer feedback

Heating and hot water boilers 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.
