Exhaust pipe shall be provided with permanent sampling ports and in accordance with national and regulatory requirements related to the construction of Jiangsu Province.
Second, the boiler produces air pollutants must be in accordance with national standards and requirements related to Jiangsu Province, construction of flue gas collection systems and centralized purification facilities, flaring has been the implementation of "coal to gas," "dry FGD" and included in discontinued closure plan outside the coal boiler, and the rest are required to install the cooling and dehumidification systems, and to ensure proper operation.
Small electric coal fired single drum 1 ton steam boilers What are the benefits, features? First, electric and coal, oil steam generating comparative advantages and disadvantages: advantages and disadvantages of coal: Advantages: coal is the most economical energy per kilogram of coal can produce more than 5,000 calories, can produce about 6 kg steam (theoretical value). Both economical than electric, fuel oil and natural gas. Disadvantages: 1, low efficiency, although theoretically per kilogram of coal can produce more than 5,000 calories, but due to the limitations of coal-fired boilers and human factors affected the Boilermakers, the real heat of the steam is converted to produce much smaller than the theoretical value, the heat utilization rate of around 60%. 2, can not do automatic control, if the device is not continuous steady steam steam that instant steam consumption fluctuations, the steam produced by the boiler with the steam in the bottom of the valley steam equipment can only let go waste. 3, need specialized operators, high labor costs. 4, do not meet the requirements of modern environmental protection, to ban small coal-fired boilers is the trend. The advantages and disadvantages of fuel: fuel meets the requirements of environmental protection, the state has not been expressly provided, however, based on current oil prices, its economy has ceased to exist. Per liter of oil can produce more than 18,000 calories, about 60% utilization, we can produce about 10 kg of steam. Which produce one ton of steam costs around 800 dollars (at current prices). The advantages and disadvantages of heating: Cons: Because electricity is converted from the other sources of energy, so the relatively high price point, once electricity can produce about 1.5 kg of steam. Calculated to produce 1 ton of steam costs about 400 yuan or so based on the current average domestic electricity bill. More expensive than coal.
Gas-fired coal fired single drum 1 ton steam boiler and gas steam boiler which is more energy-efficient? General business in the procurement of steam boilers were more often or consider production efficiency problem, we need to know what kind of fuel steam boilers more energy-efficient choice is clear, and that is the most common gas steam boiler and gas steam boiler comparison which is more energy efficient? Following on from me give you an analysis. Clear answer the same model as compared to steam boilers or gas steam boiler energy conservation, we can roughly be calculated next-ton per hour boiler full load of work to 150-160Kg coal according to the market value of fuel gas and gas to about 80m3 . A further additional energy means 'gas' is higher than the calorific value of 'coal' fuel value, and then under the same conditions, producing one ton of steam, of course, fast burning gas. Also a ton of water to generate a tonne of steam, in theory, as much heat energy is required, the low single coal market price, it is cheaper than burning gas. But better to burn coal gas and environmental protection in environmental protection. If a large amount of production if the proposed biomass boiler, coal processing than such low investment, but also more environmentally friendly.
Works coal, gas boiler steam heating device (burner) to release heat, radiation heat transfer is first absorbed by the water wall, the Wall Boiling water, a lot of steam into the drum for generating steam separator (DC furnace out), separated into the steam superheater full, by radiation, convection method and continuous top horizontal flue furnace absorption, the flue gases heat the back pass, and the superheated steam temperature reached the requested work. Power generation boilers are generally provided with a reheater, steam is used to heat the work of the high-pressure cylinder, the reheater go out of the reheat steam, the low pressure cylinder continuously to generate power. Plain speaking, a coal fired single drum 1 ton steam boiler the burning of the fuel absorbs heat energy must be water parameter (such as pressure, temperature, etc.) of the steam device. Boilers and boiler furnace divided into two parts, the pot is filled with water to the metal container, the fuel is burning furnace section heat absorb water pot furnace and burning the fuel to steam, with the basic principles of almost boiling water, the pot equivalent kettle, oven stove equivalent. A heating device (burner releases heat, radiation heat transfer is first absorbed by the water wall, the Wall Boiling water, a lot of steam into the drum for generating steam separator (DC out furnace), separated into the full steam superheater by radiation, convection method and continuous top horizontal flue furnace absorption, the flue gases heat the back pass, and the superheated steam temperature reached the requested work. power generating boilers are generally provided with a reheater for heating by high-pressure cylinder is after work steam reheater go out of the reheat steam, the low pressure cylinder continuously to generate power. plain speaking, thermal energy of the fuel steam boiler burning the water absorption becomes bound parameter (such as pressure, temperature, etc.) device steam boiler is divided into two parts and the furnace pot, the pot is filled with water to the metal container, the fuel is burning furnace section heat absorb water pot furnace and burning the fuel to steam, and the basic principles of burn almost boiling water, the pot equivalent kettle, equivalent furnace stoves. vertical coal-fired steam boiler is an energy conversion device, the energy input to the boiler with a fuel Chemical energy, electrical energy, thermal energy and other forms of high temperature flue gas, the boiler through the conversion of thermal energy must be output externally with steam, hot water or organic heat. Used for power plant, boats, locomotives and mining enterprises. Boiler the main reason of the original work is a thermal energy or heat using a fuel burning industrial production released after transfer to the water in the container, the water temperature reaches thermodynamic device necessarily needs or steam pressure in the boiler furnace pot with some two performed in conjunction with the water into the boiler in the future, the system heat soda boiler heating surface will absorb transferred to the water, the water must be heated to a temperature and pressure to generate steam or hot water, it is drawn applied. in some apparatus burning, the burning fuel may continue to evolve heat, high temperature flue gas occurs by thermal incineration convey the heat to the boiler heating surface, the temperature was gradually lowered itself, and finally discharged from the steam boiler chimney classification: First, according to the fuel is divided into: 1, coal-fired boilers, 2, oil-fired boiler, 3, gas boiler, 4, electric heating boilers, 5, nuclear boiler, 6, waste heat boiler, etc., before therebetween Up to four kinds, the most common, the lowest operating costs of coal-fired boilers, but a large area, environment pollution, the operator requested more; higher degree of fuel gas-fired boiler automation, operation cost is higher than coal, covers smaller, less operator request; electric heating boiler I have not had the operation, but the operation cost should be the highest, but a small boiler footprint, best environmental; other boiler is not introduced, due they do not understand. Second, by way of heat transfer into water tube boiler, fire tube boilers, water, fire-tube boiler fuel gas-fired boiler is usually fire tube boiler, typical model:. WNS series (horizontal combustion chamber burning boilers), such boiler features: simple structure, an additional amount of evaporation is generally small (typically ten tons or less, there are also large, but usually do not exceed 35 tons), Kai furnace boost rapid, relatively low boiler water quality request; coal-fired boilers are generally are water-tube boilers, water tube boilers high thermal efficiency, but messy configuration, the boiler high quality requested. Third, additional pressing pressure into the low-pressure boilers, medium-pressure boiler, high pressure boiler four, according to use For the day of boilers, industrial boilers, power generation, marine boilers.
