Biomass boiler introduction
Biomass boilers have a wide range of fuel sources and are renewable green energy sources. They contain almost no sulfur and little ash. The growth process can absorb all the CO2 produced by the combustion process and achieve zero CO2 emissions. Biomass energy will gradually replace coal and become one of the important 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 external dimensions, it can be divided into three types: chip (≤3mm), sheet (≤50mm), and bar (> 50mm).
Since 2003, our company has cooperated with famous domestic colleges and universities to absorb the technology from the domestic and foreign ancestors, gradually open the material boiler, and continue to modify it in practice. At present, mature and stable technology and products have been obtained. widely used. According to the characteristics and external dimensions of different biomass, we have developed four combustion systems: fixed grate, moving 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 important characteristics of our company's biomass fuel boilers are as follows: the secondary air designed and arranged in the furnace disturbs the flue gas power conditions, timely adds oxygen ash volatiles, improves thermal compliance and reduces emissions . Reasonably design the cherishment of the arch and the rear grate, and avoid the periodic microburst of the hearth. For water-containing waste, increase the length of the preheating section, provide useful heat sources for heating, or directly invest in the hot section of hot flue gas. For the gas-producing Cenling load bulge, or the waste material contains easily coking components such as glue, a large number of heating surfaces are arranged in the furnace to solve it. For the various conditions of the scrap, such as blocks, strips, flakes, chips, and powder, a variety of feeding methods and a single feeding method are designed 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 according to users' requirements for various biomass fuels to provide users with superior value products.
Benefits of biomass boilers
Biomass fuel is a new fuel supported and promoted by the state. Biomass fuel refers to rural crops such as corn stalks, wheat stalks, cotton stalks, straw, rice husks, peanut husks, corn cobs, branches, leaves, sawdust and other crops, solid waste. As a material, it is crushed, pressed, and densified to form "biomass fuel". It is a renewable resource.
The benefits of using biomass boilers for customers are mainly reflected in two aspects:
1. It can greatly save operating costs. For every 600,000 kcal of heat (1 ton of steam), 160Kg of fuel is consumed, which is equivalent to approximately RMB 208, while oil-fired boilers must consume 67Kg of light diesel, which is equivalent to approximately RMB 502.
2, can significantly reduce pollutant emissions,
Biomass particles have the characteristics of high calorific value (calorific value up to 4500Kcal / kg), effective combustion and reduced pollution. It has been tested that all types of emission indicators are lower than the standard time period requirements in the category 1 region in the “Boiler Air Pollutant Emission Standard” (GB13271-2001). Among them, sulfur dioxide and nitrogen oxides have almost zero emissions and are far lower than fuel oil (gas). )boiler.
CDZH (L) biomass-fired 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. The fuel fell on the grate, and after it was fully burned in the hearth, the flame passed through the flue gas channel of the central furnace wall and entered the rear of the body. It was turned from the ash chamber on both sides to the front smoke box, and then returned to the pot from the front smoke box 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.
1. The boiler thermal compliance 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: The atmospheric pressure hot water boiler series is an ideal choice for heating, bathing, air conditioning, and domestic hot water in various industries such as enterprises, institutions, hotels, and houses.
