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 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.

How to improve the energy efficiency of industrial boilers, industrial boilers how to improve energy efficiency 1, focusing on the transformation of practicality (1) above to recover waste heat can be effectively used. For example: high temperature organic heat boiler flue gas, but the process does not require the production of steam and hot water, attention should be considered heated by flue gas waste heat recovery techniques combustion air. (2) improved gas boiler should focus on energy-saving technologies improve the automation level of combustion control, precise control of the combustion state. (3) Consider first the application of energy-saving technologies and sophisticated equipment. 2, considering the technical nature to further improve the thermal efficiency of industrial boilers, it is necessary to consider new energy-saving technologies and equipment. Advanced (1) energy conservation technology and equipment, difficult to implement. Such as: waste heat recovery heat exchanger and the new technology: heat pipe technology, the condensed waste heat recovery technology; new water treatment device: microbial fouling and electromagnetic processing techniques (e.g., hydraulics); combustion automatic control technology. (2) spraying pulverized coal combustion technology (stratified combustion mode and suspension-fired boilers) design, construction and operation of high demand management, oxyfuel technology, such as high temperature air combustion technologies require large investments. 3, forming a complete transformation handle (1) must be considered boiler energy saving, heat insulation of synchronization is complete, sealing, and improved methods of burning fuel adjustment, and the fuel air distribution system of the inverter, reduced nicotinamide tube improved resistance to treatment. (2) pay attention to clean the boiler heating surface, and providing technical improvements boiler water, slag, ash, etc., to ensure that the boiler has good heat transfer properties. (3) the necessary training for technical operations and daily management of energy-saving equipment.

Coal to natural gas operations bunch of factors that vertical pressure steam boiler energy consumption indicators of the country are carried out in a big way, the choice of vertical steam boiler, to a large extent minus the pollution of powder, together with nitrogen oxides and other dangerous gases the press has been discharged. Energy consumption indicators is an important rule to measure vertical steam boiler, to discuss the next bunch of factors under pressure vertical steam boiler energy consumption indicators. By analyzing the relevant departments, vertical steam boiler heat loss occurs mainly includes two aspects: the proportion of non-standard sufficient combustion air with exhaust heat loss. Weaken the heat loss can be retrofitted in the vertical steam boiler chimney terminal latent heat of re-use form, or in the selection of better boiler system FGR. Combustion air ratio is not sufficiently decomposed inappropriate criteria: ordinary vertical ejector-type steam boiler burner based, air-fuel ratio can not be formed in the active mobilization. More vertical steam boiler based on a mechanical blower burner, air-fuel ratio due to the following standards several factors: air-fuel ratio standard comprises two situations: when oxygen is excessive, the excess will be an infinite cryogenic air by heat conduction, caused by rising energy vertical steam boilers, low energy consumption vertical steam boiler index; when there is insufficient oxygen, there will not be sufficient to ignite the situation, leading to low energy consumption indicators vertical steam boiler.
