Natural gas fired boiler is an inevitable trend of biomass transformation of straw pellet machine wood biomass combustion boilers has become an inevitable trend, as people's environmental awareness is gradually improving, countries and relevant departments of environmental protection and energy conservation incentives gradually introduced, burning reconstruction of coal boiler to a biomass fired boiler has become an inevitable trend. It is reported that wood biomass straw pellet production line capable of dispersing straw, wood and other raw materials processed into biomass burning particles, biomass fuel boilers provide a rich fuel, thus contributing to the transformation of enterprises biomass combustion boilers. Due to the strong state support, biomass burning particles as an alternative to coal, it has become China's fourth largest energy. British co-promote the use of wood biomass straw particle machine production lines, the production of biomass burning particles is greatly improved, greatly facilitate the process of enterprise biomass burning boiler in China. The increase in coal-fired boiler flue gas heat recovery steam recovery and necessary, and grate and transform a simple drum cited the wind, it can become a biomass wood pellet machine straw biomass pellet fuel biomass combustion boilers. While coal-fired boiler will increase business costs, but in the long run, the interests of biomass fuel boiler to the enterprise is immeasurable. With the contraction of the national policy on coal mining, the market price of coal is gradually rising. Biomass, straw wood pellet machine sufficient feedstock biomass particles, low processing costs, the use of biomass boilers, direct year savings of 5-10% in fuel costs. It is understood that use coal-fired boiler, the desulfurization necessary intervals, the biomass particles fuel sulfur content is extremely low. This complete abolition boiler desulfurization costs, reduce operating costs. Biomass fuel fired boilers can be exempt costs 80 yuan / ton; subsidies can help apply alternative fuel fired $ 200 / ton (NDRC); Also, according to the case of application of various energy saving MEP technological sector, the Ministry and other subsidies; where if a higher corporate income tax, then the application of biomass wood pellet machine straw biomass fuel particles can win policy tax shelters.
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.
When the external inspection of the 4 ton steam boiler for sale few notes below Henan fast boiler's steam boiler Xiao Bian told you about the external examination of the few notes need to be transported when the steam boiler, it is necessary to check the external steam boiler, 1, security accessories are complete, sensitive, reliable, secure attachment of the installation for compliance with relevant regulatory requirements. 2, can test gauge when necessary, the safety valve exhaust test. 3, auxiliary equipment (fans, pumps) is functioning properly. 4, automatic control equipment, signal systems and a variety of instruments is sensitive and reliable. 5, various types of door is tight, leaks and corrosion. 6, placed in the drum to the combustion chamber wall may be observed, water wall is normal, without deformation or other anomalies. 7, the combustion is stable, whether black smoke chimney. 8, steam boiler furnace wall, architecture, platforms, escalators, etc. is intact: water treatment equipment is operating properly. 9, boiler room facilities for compliance with relevant regulatory requirements, management is normal and so on. 10, the visible parts of the boiler weld cracks cracks (joints) appears. Classification of a steam boiler combustion apparatus, the four-way steam boilers for solid fuel burner layer being layered on the furnace grate stratified charge combustion. Such as: hand-burning stove, chain furnace stoker furnace. Second, the four-way chamber burner fuel mist of fine particles with the air injected into the furnace combustion furnace in suspension. Such as: Pulverized Coal, oil furnace, gas furnace or the like. Three, four boiling furnace fuel stream is lifted carrying like rolling boil under goes a combustion furnace.
Fangkuai Group has more than 60 independent intellectual property rights, advanced clean fuel boiler manufacturing technology, and jointly established a clean fuel boiler production, research and research cooperation base with Tsinghua University and Xi'an Jiaotong University. An enterprise with a R & D and test center for clean fuel boilers. The thermal efficiency of “Fangkuai” boilers can reach 107%, which has been included in the national special equipment energy-saving catalog. The company developed ultra-low nitrogen full premixed combustion condensing boilers and ultra low nitrogen emission fuel gas boilers, which are developed by the company using Ultran condensation technology.Free Chat
