(1) Before draining, adjust the boiler water level to slightly above normal. When draining, monitor the water level closely to prevent water shortages caused by draining the gas boiler. After draining, there will no longer be the sound of water flowing in the pipes. After a few moments, touch the drain with your hand. If the temperature is too high, it means that the drain valve is not sealed and the cause must be found to eliminate it.

(2) In accordance with the principle of diligent drainage, less drainage, even drainage, at least once per shift. Gas steam boiler adopts burner cooling method, two times structure, fuel full combustion, boiler operation is stable, occupies less land, spoiler plate inserted into the flue pipe, reduces the speed of exhaust smoke, increases the heat Heat exchange, improves the thermal efficiency of the boiler, reduces the cost of the user When there are more than one sewage pipe on the boiler at the same time, all of them shall be discharged in sequence. If only one part is discharged and the other part is not discharged for a long time, it will reduce the water quality of the boiler water or block some of the discharge pipes. It may even disrupt water circulation and cause a pipe explosion. When multiple boilers use drain pipes at the same time, simultaneous draining is prohibited to prevent sewage from flowing back to nearby boilers.

(3) When the boiler is burning or the load is low, the boiler water circulation is slow and easy to slag, and the sewage discharge is effective. The hot water boiler is equipped with a computerized boiling water boiler controller. All functions are stored in the intelligent chip which can realize the boiler's intelligence, digitalization, automation and humanization. The boiler intelligently controls the water temperature and automatically stops heating when the water temperature is reached. The screen comes with large fonts. Displays the temperature of the water, and you can see the temperature of the boiler water at a glance.

(4) The exhaust operation of the gas boiler should be short and intermittent, i.e., the exhaust valve should be closed every time it is opened and then opened again after it is closed. Biomass boiler: horizontal biomass boiler, vertical biomass boiler. Biomass gas heat transfer oil furnace, biomass steam boiler, biomass hot water boiler, biomass heat transfer oil furnace. Repeat this many times, relying on suction to quickly gather the slag dirt to the sewage outlet, and then centralized discharge. If the discharge time is too long, the concentration of slag in the boiler water will first increase and then decrease, which not only reduces the effect of sewage discharge, but also increases the amount of sewage discharge, resulting in a decline in local water circulation.

(5) The operation of regulating the ground flow is realized by opening the regulating valve, the value of which depends on the test results of the water quality in the tank. Regularly draining the steam hot water boiler allows the boiler water quality to meet standard requirements, maintains good water quality, slows or prevents scaling, and ensures the use of the steam hot water boiler.
