fuel gas steam boiler for egypt

Operating cost comparison of different fuel fuel steam boiler for egypt below Henan fast boiler with small series to introduce the company's operating cost comparison of different fuel steam boiler. Refers to a steam boiler water heated to a certain temperature parameters, and the production of industrial steam boiler, water is heated into steam in the steam drum, the fire in the furnace emits heat, it is the principle of the steam boiler. Steam boiler belongs to special equipment. Gas: Advantages: clean energy, high thermal efficiency and save costs. Disadvantages: Restricted gas on condition. Generating a cost of about 2.4 tons of steam million (calculated as the price of 3.2 yuan gas / side) fuel: steam boiler advantages: no pollution, high efficiency, no fuel limitation. Disadvantages: higher operating costs. Produce one ton of steam costs about 594 yuan (fuel prices by 9.5 yuan / kg calculated) electrical heating: advantages: no pollution, no fuel limitation. Disadvantages: is a secondary energy, high operating costs to produce one ton of steam costs about 700 yuan (electricity prices by 0.6 yuan / kWh). Coal: advantages: low operating costs. Disadvantages: pollution, restrict the use of some areas, the cost of one ton of steam produced is about 150 yuan (coal prices by 900 yuan / ton).

Young workers from Tianjin, said the training is very timely, went through the last heating period we have a lot of operational settings, fault verification, exclude doubt want to learn the skills, the training targeted and very practical, lecturer lectures easy to understand, is a rare and rewarding "charge" in the hope the group can fast side of this type of open class continue gone out of existence, we have a great need for such training.

The reason you need to know the boiler energy consumption (reheat steam temperature) reheat steam temperature problems 1. Circumstances reheat temperature rises 1.1 Move boiler furnace flame center, furnace outlet temperature increases (see main economic indicators No. 5 boiler exhaust gas temperature). 1.2 coal increased too fast. 1.3 Excess air amount is increased. 1.4 pulverizing system start-stop. 1.5 Automatic control of the reheater desuperheating water improper adjustment. 1.6 reheater sootblowing time poor choice. 1.7 feed water temperature is low. 1.8 the high pressure turbine exhaust temperature is high. Next to the 1.9 high leakage, high reheater inlet temperature. Hot and cold extraction section greater then 1.10. 1.11 boiler heating surface design is unreasonable, over-temperature reheater tube wall, forced cooling operation. 2. Reheat the following partial flame temperature is lowered center 2.1: burner tilt deviation, hem; burner is switched from the upper to the lower layer, the lower layer or to an excessive amount of the powder; volatile coal fraction is increased, the pulverized coal thinning, water reduction. 2.2 reheater heating surface fouling, slagging, fouling the interior. 2.3 Save reheat the heated drain valve. 2.4 automatic adjustment inappropriate, excessive reheater desuperheating water. 2.5 feedwater temperature. 2.6 economizer and water wall sootblowing time poor choice. 2.7 reduce the amount of coal too fast. 2.8 # 1, # 2 high pressure heater is disabled, increasing the reheated steam flow.

The main difference between the gas boiler and gas fuel steam boiler for egypt What is the main difference between what gas boilers and gas steam boiler is? Nominally, a clear distinction between gas and steam boiler wherein the boiler fuel gas is different. The former use of natural gas, which uses coal. I think a lot of user concerns boiler is why they should cancel gas-fired boiler, because many people have purchased and used the gas boiler. If they switch to gas-fired boiler, it will be a huge expenditure. First, according to the current direction of development of the ecological environment of China, gas boilers will gradually be replaced by gas-fired boiler or other clean and green energy boilers, gradually withdraw from the stage of history. To say a big difference between the gas boiler and gas steam boilers, gas-fired boiler is mainly due to the elimination of environmental protection. From the fuel supply portion, only a gas boiler tube connected to the boiler; gas boiler needs coal field, coal (with or artificial), coal transportation, handling, storage and loading of coal boiler process. It will produce dust, causing serious pollution to the people's living environment. From the point of view of atmospheric emissions, natural gas is very small dust content, substantially negligible; high ash content of coal, the ash content of about 10-30%, the combustion smoke. If dust emission reduction facilities, emissions will increase; if more dust removal facilities, the corresponding costs will increase, this is not a long-term solution. In addition, the sulfur content of natural gas is very small, dust removal, desulfurization and denitrification can get gas boilers, gas boilers need only consider the denitrification problem. From the other point of view of waste disposal, natural gas substantially free of other contaminants, especially in city gas. In the case of coal, the coal field (especially small boilers mainly built in the open air) to produce coal slurry water during the rainy season, or sink into groundwater. When entering the surface water, the combustion ash conveyance of dust is generated. Of course, there are differences also in other ways. For small boilers, gas boilers are more energy efficient than gas boilers, equipment flow is simple, small footprint, low operating and maintenance costs, and so on. These are the main difference between the gas boiler and gas steam boilers, as well as the significance out of gas boiler. As can be seen, the use of gas-fired boiler is the trend of the whole society.
