comparison of low pressure and high pressure boiler

Industrial comparison of low pressure and high pressure boilers prevent scale measures what? Industrial boilers prevent scale measures what? To ensure that no knot or less furring industrial boilers, water treatment work must strengthen measures usually taken include the following items. (1) pretreatment of raw water in the raw water to be taken using the coagulating sedimentation, filtration, purification and the like. (2) the outer pot pot water treatment comprising oxygen and softening process. Raw water often dissolved oxygen, carbon dioxide and other gases, is likely to cause boiler corrosion. Industrial boilers generally use heat deaerator, water for Ca2 +, Mg2 + and other harmful ions often used ion exchange softening. (3) pot-treatment chemical is added directly into the furnace slag fluidity reaction occur through ionic water chemicals with the furnace, and then discharged through the sewage in time. This method is suitable for small-scale low-pressure boilers. (4) Operation reasonable industrial boiler blowdown during operation, due to the continuous delivery of external steam, boiler water is reduced, resulting in increase in solid concentration in the furnace was dissolved, a precipitate gradually accumulated and formed in the long term high temperature scale, so We must be regularly sewage, reducing scale production. If it is found in boiler water alkalinity is too large, increase the sewage; on the contrary, should be reduced.

Fang quick to join hands farmers Springs, win-win cooperation, to create a new future environmental Speaking farmer spring, everyone will think so mind a slogan - "Nongfushangquan a little sweet." As a Chinese brand strength index (ChinaBrandPowerIndex, referred to as C-BPI) ranked first brand of mineral water, Nongfu Spring adhere to never use city tap water, every drop of Nongfu Spring has its source in the concept of environmental protection, we are committed to producing the most human needs drinking water containing natural mineral elements.

Gas-fired steam comparison of low pressure and high pressure boiler water treatment gas steam boiler steam boiler water treatment gas is a kind of industrial boilers, in recent years, with the recognition of such equipment, it has been applied in a variety of industries. Found practical application, in the course of which water will be treated. So we know what the reason for this is that by analyzing the right cause gas steam boiler water treatment are the following:? 1 to prevent scaling and sludge buildup; 2 sulfate and silicon: silicon and sulphate salts often precipitate in the boiler without forming a metal sludge, it is difficult to prevent the precipitation; 3 iron and sodium: iron will be dissolved or suspended is deposited on the metal surface. Because of the high solubility of the sodium compound, usually only water will be deposited near dryness; 4 Hardness: dissolved calcium and magnesium salts referred hardness. When the water vapor produced by evaporation is deposited on the pipe surface hardness. This compound due to the solubility of calcium and magnesium in water is relatively low easily precipitated, this fouling was reduced thermal conduction and cause overheating of the metallic pipe. Natural water hardness of more than a few ppm to 500ppm differences, high-pressure boiler only allowable 0 ~ 2ppm.

At present, small coal-fired comparison of low pressure and high pressure boilers are gradually replaced by clean energy boilers such as gas boilers and biomass-formed fuel boilers, and the operating efficiency of gas-fired boilers is higher because gas-fired boilers burn quickly, generating large amounts of power then coal-fired boilers. It is 20% more efficient and emits less pollutants, which is more beneficial to maintain the environment. Improving the thermal efficiency of gas boilers and making gas boilers more economical is the goal pursued by the boiler industry. The following are several ways to improve the thermal efficiency of gas boilers:

1. The design of the boiler should be reasonable, and the unreasonable boiler structure will cause waste of heat or allow the heat to be consumed in the middle of the cycle.

2. The pipeline connection of the boiler should be checked frequently. If there is any leak, stop the furnace immediately to prevent the occurrence of air leakage.

3. The gas boiler can also play a role in heat recovery, collecting the recycled hot water and reusing it, which is a method to improve the combustion efficiency of the boiler.

High pressure vs low pressure propane burner?

2020-2-26 · I recently acquired a camp chef explorer dual burner cook top. It is a low pressure system and doesn't get hot enough to light charcoal or fry fish. I contacted the manufacturer, and they said I could convert it to a high/low combination by changing the burner, spring, valve, manifold, air vent and hose/regulator. This didn't make much sense to me.
