10 ton industrial coal steam boiler
Henan gas boilers and waste heat boilers have different it as long as the difference between Henan gas boilers and waste heat boilers are: 1 boiler heat source Henan gas is to use the medium of combustion (coal oil gas, etc...) Is obtained, and the heat source waste heat boiler is the use of industrial combustion waste heat waste heat. 2. Structure of Henan gas boiler and a bit more complex ancillary equipment, and waste heat boiler structure is relatively simple, the kind of industrial boilers and more, waste heat boiler is now more straight-through waste heat boiler. 3. parameters Henan gas boiler (pressure, level, temperature) and the like can be easily controlled because the combustion control, the operating parameters of the waste heat boiler is difficult to control, the operation of the heat source is a waste heat boiler with a combustion cycle in an industrial furnace varies . 4. Henan gas-fired boiler is mainly used for gas and steam turbine power generation and other support, waste heat boilers are generally equipment industrial furnace, that there are energy saving and environmental protection.
Factors which influence energy-intensive industrial boiler energy-intensive industrial boilers factors influencing factors which have high energy consumption of industrial boilers which have 1, energy consumption is low management level industrial boiler is too large, are long-term presence of many companies in the current . On the one hand understanding of the enterprise energy conservation boiler is still not sufficient, on the other hand the energy management level is still at a low level, and even some companies even the most basic measuring instruments are not equipped. In order to reduce operating costs, many companies have to buy the old boiler use, lack of components purchased fuel means of inspection. Even in the case of raw coal screening is not performed, it is directly put into production use, it is difficult to ensure full combustion of coal. Not only the thermal efficiency is low, but also resulted in a waste of fuel. 2, heat recovery is poor combustion is incomplete, the situation is the high rate of heat loss is extremely common in industrial boilers used in the process, saving the main parameters of the boiler will be exceeded. Economizer function is to heat energy recovered, but in actual use, heat recovery efficiency is very low. In this case, do not use a lot of boiler economizer direct altogether, inevitably produce exhaust gas temperature is too high. Meanwhile, return the device and steam condensate recovery, it has not been fully appreciated and better use, some are put to use in the boiler after installation, and did not take appropriate measures to deal with poor recycling effect. 3, lack of effective supervision of the level of energy service work, depends largely on the level of experience and technical personnel. But in practical terms, due to the lack of technical personnel, resulting in the energy service work at the level of the low. Various enterprises produced energy-saving products with high imitation, coupled with the lack of effective supervision of energy-saving measures, resulting in the entire market of energy-saving products more confusing. The effect of not only energy-saving effect is not ideal, and to transform the poor, the performance of energy-saving products remains to be greatly improved. Market confusion, vicious competition phenomenon has not been fundamentally curbed.
Boiler startup startup boiler combustion adjustment method should pay attention to the flame monitoring, combustion and make adjustments as follows: (1) correct the ignition. Adequate ventilation furnace before ignition, the ignition first investment ignition device (or torch), then turn the gun. (2) diagonally administered fire mouth, pay attention to timely switch, the flash point was observed nozzle suitable fire, flame sought uniformly distributed in the furnace. (3) to adjust the lead note, air volume, furnace pressure should not be too large. (4) in particular to monitor exhaust gas temperature when combustion instability, the occurrence of the back pass to prevent the secondary combustion. (5) to maximize the temperature of primary air, secondary air is fed reasonable depending on the fuel. Adjusting the temperature difference between both sides of the cigarette. Do pulverizing system-OFF stable (6) operation. Stoker coal under stable powder machine speed and stability. Coal with wind stability and oxygen stable. Steam temperature, steam pressure increase stability and load stability liter.
Hebei province is the use of industrial boilers, countless large and small boilers, air pollution caused by coal-fired boiler is one of the problems of governance in Hebei Province, and therefore become a major coal-fired boiler control of air pollution in Hebei Province direction. Coal-fired auxiliary boiler control work steadily, the Hebei provincial government to develop a "" comprehensive management of air pollution in Hebei provincial financial assistance fund management approach ", the boiler subsidy detailed as follows:
1, rural areas electricity instead of coal subsidies
The household equipment purchase and install (including line transformation indoor) 85% of investment subsidies, the maximum subsidy per household amount not more than 7400 yuan, the provincial and city and county respectively 50%, the rest borne by the users themselves.
Residents give electricity for heating 0.2 yuan / kwh subsidies, provincial, city and county average bear, the highest household electricity 10,000 kwh subsidies, subsidies and standards tentatively scheduled for three years.
2, substitution of gas for coal in rural areas subsidy standards
The household gas equipment purchase and install the 70% investment subsidies, the maximum subsidy per household amount not more than 2700 yuan. Provincial cities and counties and respectively 50%, the rest borne by the user.
Heating gas for customers who use 1 yuan / cubic meter of subsidy per household per year up to 1200 m3 gas subsidies, provincial, city and county average bear, subsidies and standards tentative three years.
Given the highest building in the village of pipelines family home investment subsidies of 4,000 yuan, 1000 yuan assume the provincial, city and county to bear 3,000.
3, coal-fired boiler subsidy governance standards
Subsidies for coal-fired boilers, eliminate subsidies, a separate ban demolition of 30,000 yuan / tons of steam, the implementation of clean energy transformation of 80,000 yuan / tons of steam.
4, thermal power shutting down out of subsidies
Provincial for shutting down the unit by 300 yuan / kilowatt award given up, have been included in the national "Thirteen Five." Plan for shutting down the unit, illegal construction unit, run-of-life choice except unit and power capacity index trading.
