The inlet gas pressure is different for different capacity boiler, for example, the pressure for 2 ton steam capacity boiler is about 8~10KPa, while for 4 ton steam capacity boiler is about 12~25KPa. You can tell us the boiler capacity you want, we will help you to get the gas inlet pressure.
The coal-fired boiler refers to the boiler uses various types of coal as fuel and converts the heat of coal to steam or hot water.
There are generally two calculation methods of the circulating water volume of a coal-fired hot water boiler. One is to calculate the hourly water volume of one square meter and the other is to calculate the design parameter volume of every ton. As for the make-up water volume of this type of boiler, it is usually calculated as 1% to 3% of its total circulating water.
Four factors are related to the failure of the draft fan of the biomass-fired boiler. The factors are electric, electrical motors, dampers and induced draft fans. Therefore, if the draft fan breaks down, you can check the electric and electrical motor first, then you can check the damper and the induced fan.
1. The storage tank is used to store the heat medium oil of the heating system;
2. The storage tank is used to receive the overrunning heat medium oil；
3. The storage tank is used to supplement heat medium oil for the heating system;
4. The storage tank should be placed at the lowest position of the system;
5. A firewall should be placed between the storage tank and the thermal oil heater;
6. The storage tank should be operated at a low liquid level.
Volatile matter in coal refers to the components of coal, except for moisture, which are liberated at high temperature in the absence of air. This is usually a mixture of short- and long-chain hydrocarbons, aromatic hydrocarbons and some sulfur. Volatile matter also evaluate the adsorption application of an activated carbon. The volatile matter of coal is determined under rigidly controlled standards. In Australian and British laboratories this involves heating the coal sample to 900 ± 5 °C (1650 ±10 °F) for 7 min. Also as the rank of coal increases the volatile matter decreases (AMK).
Maintenance of the burner: thoroughly clean the rotor plate, ignition device, filter, oil pump, motor and impeller system, and add lubricant to the connecting rod device of air valve. Retest the combustion condition.
Although biomass-fired boilers are environment-friendly boiler products, there are also some situations that biomass-fired boilers can’t be used. Main reasons as follows:
Fuel restrictions: The fuels that contain synthetic compounds can’t be used as the fuel of a biomass-fired boiler, such as waste wood furniture, waste paper, production and domestic waste.
The gas consumption of 10 tph gas-fired boiler is related to technical parameters.
Such as heating surface layout, heat preservation effect, heat loss, water capacity, etc. The calculation formula of gas consumption of 10 tph gas-fired boiler is as follows:
=10 tph gas-fired boiler output÷ thermal efficiency ÷calorific value of natural gas
= 6,000,000 kcal ÷ 0.98 ÷ 8,600 kcal / h = 712 m3
Therefore, the gas consumption of 10 tph gas-fired boiler is 712 m3/ h
The gas consumption of the above gas-fired boiler is calculated at full capacity. In practice, the gas consumption changes with the operation load and operation conditions. In addition, if thermal efficiency of the gas-fired boiler is different, the gas consumption is different, too. The higher thermal efficiency is, the lower gas consumption is.
