(1) Before discharge, the boiler water level should be adjusted to slightly higher than the normal water level. When discharging water, closely monitor the water level to prevent sewage discharge from causing water shortages in gas-fired boilers. After draining, there will no longer be the sound of water flowing in the pipe. After a while, touch the sewage pipe with your hand. If the temperature is too high, it means that the blowdown valve is not tightly sealed, and the cause must be found to eliminate it.
(2) According to the principle of diligent discharge, less discharge, and uniform discharge, discharge at least once per shift. The gas-fired steam boiler adopts a lower burner mode, a two-pass structure, full fuel combustion, stable operation of the boiler and less space. At the same time, a spoiler is inserted in the flue pipe to slow down the exhaust rate and increase the heat exchange. The boiler has high thermal efficiency and reduces User fees When there are multiple sewage pipes on the boiler at the same time, all the sewage pipes must be discharged in sequence. If only one part is discharged, and the other part is not discharged for a long time, the water quality of the boiler water will be reduced or some sewage pipes will be blocked. It can even disrupt the water cycle and cause the pipeline to explode. When multiple boilers use sewage pipes at the same time, it is forbidden to discharge water at the same time to prevent the sewage from returning to adjacent boilers.
(3) When the boiler is burning or the load is low, the boiler water circulation is slow, slagging is easy to accumulate, and the sewage discharge effect is good. The hot water boiler is equipped with a computerized boiling water boiler controller, and all functions are stored on a smart chip, which realizes the intelligentization, digitization, automation and humanization of the boiler. The boiler intelligently controls the water temperature and automatically stops heating when the water temperature is reached; large screen fonts The water temperature is displayed, and the boiler water temperature is clear at a glance.
(4) The discharge operation of the gas boiler should be short-lived and intermittent, that is, the exhaust valve is closed every time it is opened, and then opened again after it is closed. Biomass boilers: horizontal biomass boilers, vertical biomass boilers. Biomass gas heat conduction oil furnace, biomass steam boiler, biomass hot water boiler, biomass heat conduction oil furnace. Repeat many times, relying on suction to quickly converge the slag to the sewage outlet, and then discharge it in a concentrated manner. If the discharge time is too long, the slag scale concentration in the pot water will be high first and then low, which not only reduces the discharge effect of sewage, but also increases the discharge of sewage, resulting in a decrease in local water circulation.
(5) The adjustment operation of the ground flow is realized by the opening of the regulating valve, and the value is determined by the test result of the water quality in the tank. The regular discharge of the steam hot water boiler can make the water quality of the boiler meet the standard requirements, maintain good water quality, slow down or prevent fouling, and ensure the use effect of the steam hot water boiler.
