Inspection of gas boiler before ignition: 1. Boiler, fan and boiler circulating water pump should be in good working condition.. Safety accessories (such as pressure gauge, water level gauge, boiler explosion door, etc.) should be complete, flexible and reliable.. The water level of the hot water tank is higher than 2/3 of the height of the tank (but lower than the overflow port). Boiler water level is full.. Keep the flue clear and open the air door of the induced draft fan.

Boilers are widely used in various industries and are related to our food, clothing, housing and transportation. As a kind of high-temperature and high-pressure thermal energy equipment, pressure gas boilers are widely used special equipment. If you do not pay attention to the use, the operation is wrong, it is easy to cause equipment damage and serious consequences.

In industrial heat applications, the hot water gas boiler operating system is more complex, including the boiler system and piping system, as well as the later hot water gas boiler system operation should pay attention to some of the situation? Heze boiler for you in detail:

 

Hot water gas boiler operation matters needing attention

 

(1) When starting a large circulating water pump, the bypass valve should be opened first to prevent the boiler or radiator from being damaged due to too fast starting pressure. After the boiler is in normal operation, the main water valve should be opened and the bypass valve should be closed.

 

(2) As the water temperature rises and make-up water enters the boiler, the gas will continue to precipitate, and the exhaust valve should be opened frequently.

 

 

Wall-mounted boiler manufacturers: a brief understanding of the gas wall-mounted boiler

2022/05/26 14:23

The gas wall hanging boiler of the wall hanging boiler manufacturer originated in Europe and has a history of hundreds of years. Today, wall-mounted boilers from Europe have a long history of development, mature technology and excellent quality, and have become the darling of the market. The full name of the wall hanging furnace is: gas wall hanging furnace. Compared with the gas instant water heater, it is a rapid heating device without a hot water storage device, but there are fundamental differences in structure. The gas wall-mounted boiler of the wall-mounted boiler manufacturer has a strong household central heating function, which can meet the heating needs of multiple rooms. In addition, it can also take into account the function of hot water bath. The heating function of the gas wall-mounted boiler is affected by the local climate conditions and building insulation conditions. With anti-freezing, dry burning protection, accidental flameout protection, over-temperature protection, water pump anti-lock protection and other safety protection measures. It can be connected with the indoor temperature controller to realize personalized temperature adjustment and energy saving. According to statistics, the use of indoor thermostats can save 20-28% of gas costs. What factors are related to the consumption of gas wall-mounted boilers of wall-mounted boiler manufacturers? 1. The heating power of local gas wall-mounted boilers can be reduced. 2. The average temperature of indoor wall-mounted boilers in winter is a thermal insulation measure for many big cities. Even if the room does not have heating facilities, the indoor temperature can reach 13 ℃ to 15 ℃, some small and medium-sized cities and farmers.

How to judge the electrolytic cell yin and yang pole?

First of all, look at whether [anode] is an inert electrode (it will be clearly stated in the question) if it is not an inert electrode, such as copper, then copper takes part in the reaction: Cu-2e = = = Cu2 if it is an inert electrode, then only the ion anode in the solution needs to be considered as anion and the cathode as cation anode

What is a reference electrode

The reference electrode is the electrode used as a reference for comparison when measuring various electrode potentials. The electrode to be measured and the reference electrode of the accurately known electrode potential value constitute a battery, and the electromotive force value of the battery can be measured to calculate the electrode potential of the measured electrode. The electrode reaction carried out on the reference electrode must be a single reversible reaction with stable electrode potential and good reproducibility. Usually, the slightly soluble salt electrode is used as the reference electrode, and the hydrogen electrode is only an ideal but not easy to realize reference electrode.

Basic requirements for reference electrode

The reversibility of the electrode is better and it is not easy to be polarized. This requires that the reference electrode is reversible and the exchange current density is large (10-5A/cm2). When the current flowing through the electrode is less than 10 − 7A/cm2, the electrode is not polarized. Even if a slightly larger current flows for a short time, the potential can quickly return to the original value after the power is turned off.

Electrode polishing

The first step treatment of the solid electrode surface is mechanical grinding and polishing to the degree of mirror surface. In particular, when an inerting layer and a strongly adsorbed layer are present on the electrode surface, mechanical treatment is necessary. (However, mechanical polishing will cause certain damage to the electrode, so please operate carefully.

The anodes are anions, the cathodes are cations The anode loses electrons and the cathode gains electrons.
