The common methods for boiling the gas-fired boiler:
1. Sodium carbonate (Na2CO3) or trisodium phosphate (Na3PO412H2O) and other drugs are used, and the dosage is calculated as per cubic meter of boiler volume, with the former being 5 kg and the latter being 3 kg;
2. Close the front manhole, hand hole and main steam valve (main water outlet valve), open the manhole of the upper drum, inject the prepared solution into the drum at one time, then close the manhole and open the emptying valve...
With the enhancement of environmental awareness, gas-fired boilers have been popularized all over the country because of their high combustion efficiency and environmental protection emissions, and have become mainstream products in the market after coal-fired boilers. When enterprises buy boiler equipment, the size of gas boiler is also an important parameter. Here, ZOZEN Boiler, a professional gas boiler manufacturer, has summarized the size and model parameters of two common gas boilers for e...
An Interlock in the boiler’s control system is a programmed or hardwired condition that forces a device to be in a pre-determined or permissive state before the process can continue.
Depending on design pressure, fuel type, either liquid, gas or solid, all steam boiler require interlocks to sequence the operation and to prevent damage to the boiler. Examples of such devices are High or Low Boiler Drum Water Level, Low Boiler Feed Pump Pressure, High or Low Fuel pressure, High or Low Atomization pressure (oil fired), Proof of Ignition, Proof of Flame, FD and/or ID (solid fuel) Fan Motor Operation or combustion air pressure, Damper or Valve position and High Boiler Steam Pressure as well as O2 and furnace temperature.
Here, we'll address four of the key mechanical benefits that serpentine coil heaters have to offer.
1. Coil Replacement
Coil replacement in serpentine industrial coil heaters is notably easier than that in helical coil heaters. With serpentine coil thermal oil heaters, you can replace one tube at a time instead of replacing the entire coil. This can save you thousands of dollars on the cost of purchasing a new helical coil in its entirety. Because the coil replacement can be taken care of quickly, you'll also save hundreds of thousands of dollars by avoiding excess facility downtime.
The boiler manhole-lids are mounted from the inside of the boiler so that the boiler pressure will help to keep them tight. Hence the manholes have to be elliptical in shape to make it possible to take the lid out from the boiler.
The circulating pressure of a thermal oil boiler is generated by the driving of the circulating oil pump to the thermal oil circulation. Generally, the working pressure of the thermal oil pump is 4 ~ 8kg / cm2. Actually, the pressure of the thermal oil pump differs from different working conditions.
What are the factors that affect the maximum pressure of thermal oil heater?
1. Pressure of circulating hot oil pump
The pressure of liqu...
Boiler environmental factors are an important aspect of managing boiler control safety, and users need to correctly identify boiler environmental factors. The environmental factors of different boiler rooms are different. Here we mainly introduce the environmental factors of gas boilers.
Gas boiler environmental factors
1, Lighting lamps, short-circuit, leakage cause fire, discarded
2, Burn the boiler, which produces harmful gases
3, Sanitary cleaning, waste cleaning tools, garbage
4, Boile...
There are many factors that affect the operating cost of the boiler, among which the insufficient combustion of the coal-fired boiler directly leads to an increase in the cost of the boiler. Therefore, users should adjust in time during daily operation and use to avoid insufficient combustion of coal-fired boilers.
Causes and treatment of insufficient combustion of coal-fired boiler
1, Insufficient air volume; Need to increase the air intake,
2, poor ventilation, insufficient oxygen supply, s...
