Brief Introduction of New Biomass Hot Water Boiler of Shitong Boiler in 2015
Biomass boiler has a wide range of fuel sources and is a renewable green energy source. It contains almost no sulfur and little ash. Its growth process can absorb all the CO2 generated during the combustion process and achieve zero CO2 emissions. Biomass energy will gradually replace coal and become one of the main energy sources. Biomass fuels include straw, wood branches, bamboo and wood processing waste, grain crusts, nut shells, sugar residues, oil residues, etc. According to its shape and size, it can be divided into three types: chip (≤3mm), sheet (≤50mm), and bar (> 50mm).
Since 2003, our company has cooperated with well-known colleges and universities in China, absorbed the technology of advanced domestic and foreign counterparts, gradually opened up the material boiler, and continuously improved it in practical operations. At present, mature and stable technologies and products have been widely used. . According to the characteristics and shape of different biomass, we have developed four combustion methods: fixed grate, movable grate, chain grate and chamber combustion. There are three main structures: horizontal water pipe, single vertical and double vertical, four series. Biomass fuel boiler. Different from the structure of coal-fired boilers, the main features of our company's biomass fuel boilers are as follows: the secondary air designed and arranged in the furnace disturbs the flue gas power working conditions, timely supplements the oxygen ash volatiles, improves thermal efficiency and reduces emissions. Reasonable design guarantees the protection of the arch and the rear grate, and avoids the periodic microburst of the hearth. For moisture-containing waste, increase the length of the preheating section, provide an effective heat source for heating, or directly input the hot section of hot flue gas. For the peak load of gas consumption, or the coke-containing components such as glue in the waste material, a large number of heating surfaces are arranged in the furnace to solve the problem. For the waste, there are blocks, strips, flakes, chips, powder and other states, design multiple feeding methods and a single feeding method for users to choose.
Compared with coal-fired boilers, the cost of biomass fuel is low, which significantly reduces operating costs. Our company can individually design for the various requirements of users of different biomass fuels to provide users with the best value products.
2015 new CDZH / CDZL biomass hot water boiler detailed introduction
CDZH (L) biomass horizontal atmospheric hot water boiler is a horizontal three-pass water-fire-fire tube mixed boiler. A bunch of threaded smoke pipes is arranged in the drum. There are light pipe water-cooled walls on the left and right sides of the hearth. Use light block grate, equipped with blower and induced draft fan for mechanical ventilation. After the fuel falls on the grate and is fully burned in the hearth, the flame passes through the flue gas passage in the middle furnace wall and enters the rear of the body. It is turned from the embers room on both sides to the front smoke box, and then returned to the pot The tube bundle enters the dust collector through the rear smoke box, and is then drawn by the induced draft fan through the flue to the chimney and discharged to the atmosphere.
Biomass hot water boiler features:
1. The boiler thermal efficiency is above 78%, which is higher than the "General Technical Conditions for Industrial Boilers".
2. Quick installation leaves the factory, after the use of the site, install valve instruments, drums, induced draft fans, flue air ducts, dust collectors and water circuits, etc. can run, and has the characteristics of quick start of fire.
3. Easy installation and moving can save a lot of infrastructure investment. Scope of application: Atmospheric hot water boiler series is the ideal first choice for heating, bathing, air conditioning and domestic hot water in enterprises, institutions, hotels, schools and other industries.
