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.

We have long known that fast boiler this brand, high-tech enterprises in Henan Province, the most influential brand, technology entrepreneurs contribution to enterprise and many other honors, so that our brand is very interested in each other fast. Through this collaboration, proving once again that our decision is not wrong, 15 tons of steam condensing gas boiler provides steam to fully meet the needs of our dairy products processing plant. --customer feedback

If you know a little about chemistry, you may know that the sulfur content of oil and coal is roughly equal, but ask what low-temperature corrosion of oil-fired boilers is much more serious than coal-fired boilers, for two main reasons:

1. 90% of ash in coal-fired boiler, especially coal powder furnace, is taken away by flue gas, sulphuric acid steam formed in flue gas is absorbed by fly ash in flue gas, so that sulfuric acid vapor in flue gas is reduced, and about half of sulfur remains in ash when coal is burned. When the oil is burning, the sulfur content in the fuel almost all changes to the ash in the SO2, fuel, the fly ash in the flue gas is very little, and the adsorption ability to the sulphuric acid vapor in the flue gas is very weak.

2. The hydrogen content of oil in the oil-fired boiler is about 11%-12%. The combustion of each ton of fuel oil can produce about 1 ton of water vapor, and the partial pressure of steam in the flue gas is higher than that in the case of coal-burning.

First, when the flue temperature dropped to below 50 ℃ Solution: Check the tail may enter the flue if heated, while the flue thoroughly remove soot. No burning flue tail, can be re-started ignition; if burning, should be replaced, repaired burning member. Second, the combustion chamber when the negative pressure is too large Solution: When the exhaust gas temperature close to the temperature of the injected steam, or less than 150 deg.] C over 1 hour and stable, open the inspection hole inspection; after inspection after confirming the fire source, before start the fan ventilation. Third, shutdown or fire, air gun valve ajar solutions: reinforcing and electric 2 tons steam boiler price feed water drainage, or open the valve economizer recirculation tube to protect the economizer is not burning. Fourth, Kai, during shutdown lower furnace temperature, a solution of unburned fuel in the furnace: extinguishing device immediately put into vapor, carbon dioxide or other devices off fire. Five burning improperly adjusted, with insufficient wind or with the wind unreasonable Solution: Close the flue duct and baffle around the door opening, start sending prohibited, induced draft fan. These are the methods of electric heating steam boiler fast boiler to provide you with the handling of soot in the chimney, if you use electric steam boilers, with more than five can control their own boiler equipment need to be cleared up the flue, and select the appropriate method .
