coal steam boiler for paper making dyeing factory
Gas boiler refers to a container for generating steam and hot water from natural gas(Calorific value 10000 kcal/Nm³), LPG(Calorific value 22929 kcal/Nm³), artificial gas(such as city coal gas, Calorific value 3000-4000 kcal/Nm³), biogas(Calorific value 5200-6000 kcal/Nm³) and other fuels. In general, gas boilers are usually packaged boilers.
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 steam boiler for paper making dyeing factory 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.
Main contents of boiler energy efficiency test：
1. Boiler thermal efficiency test: a) determination of boiler evaporation; b) boiler excess air coefficient detection; c) exhaust smoke temperature detection; d) fuel combustion efficiency test; e) boiler thermal efficiency test; f) fuel consumption; g) Steam to coal ratio.
2. Boiler new product stereotyped energy efficiency test: Determine whether the boiler thermal performance indicators are consistent with the design and determine the operation mode of the equipment. Such as boiler evaporation, boiler thermal efficiency, combustion efficiency, various heat losses and so on.
3. Boiler operation adjustment test: Determine the most economical operation mode of the boiler and identify defects in the boiler operation. Such as boiler maximum load, boiler minimum load, fuel requirements, economic load, reasonable exhaust gas temperature, optimum wind coal ratio, excess air ratio, secondary air ratio and so on.
4. Comparative test of thermal performance before and after boiler reform: changes in evaporation, effects of combustion, thermal efficiency of boilers, etc.
5, fuel industry analysis, elemental analysis: to judge the quality of oil, gas and other fuels, easy for enterprises to control the quality of fuel into the plant.
6, water quality testing, scale analysis: determine the quality of water, control the boiler water indicators to prevent boiler fouling.
Car accessories types of complex processing, such as the interior wall Peng, floor, seats, instrument panels, sound systems, many processes required in a high temperature environment, the temperature becomes optional metrics wind Visteon hot water boiler. It is reported that Dongfeng Visteon existing boiler equipment can not reach the growing production needs, the introduction of fast boiler production of two parties often piezoelectric hot water boiler (CWDR1.8-95 / 70-II) in 2017.
