The cost of a rice husk fired steam boiler is about $4,000 – $18,500, depending on a number of factors. A Rice husk fired steam boiler (RHFSB) is a type of biomass boiler that converts rice husk into steam for use in manufacturing processes. There are several different types of RHFSB, all with varying efficiencies and costs, but the main difference between them all is how they are fired. The most common method for firing an RHFSB is with wood chips or other biomass materials such as agricultural waste or sawdust.
What is a rice husk boiler?
Rice husk steam boiler
A rice husk boiler is a type of biomass-fired steam boiler. It is used in the processing of food, pharmaceutical, chemical, and other industries to generate steam. The use of rice husks as fuel for power generation has been practiced for many years in South East Asia and China.
Rice husk is a byproduct from the milling process where it’s removed from the polished rice kernel after milling to be discarded or used as animal feed. Rice is a widely cultivated plant globally with large production in Asian countries such as India, China, and Indonesia which account for about 50% of the world’s total output.
How steam is produced by a rice husk boiler?
Rice husk burner for steam boiler
A rice husk boiler is a device that produces steam and electricity from rice husks, which are burned in a furnace. The heat from the furnace turns water into steam. Then, this steam is used to turn a turbine which turns an electrical generator (Eg: Stirling engine). This generates electricity from the shaft of an engine or turbine that has been rotated by thermal energy contained in steam generated by burning rice husks.
A rice husk boiler is essentially a large furnace that uses natural gas to turn water into steam. The heat generated by the burning of rice husks in the furnace boils the water, turning it into steam which then spins a turbine and produces electricity.
The process begins when you start up your rice husk boiler and ignite the fuel inside of it (usually coal). As soon as the fuel starts burning, it heats up the water inside large pipes that are connected directly to each other. This causes the air pressure inside these pipes to rise quickly until they reach a point where they have enough pressure for water vaporization—this means that at this point there is enough heat energy available for you to turn liquid water into vapor or gas (i.e., steam).
How does a rice husk fired steam boiler work?
Rice husk fired boiler
A rice husk fired steam boiler works by burning rice husks in the furnace, which generates heat. The heated water is then turned into steam and used to turn a turbine that drives a generator. The electricity produced can be used to power lights or other appliances in your home.
The rice husk fired steam boiler is a simple, reliable, and cost-effective solution for generating electricity. In this type of boiler, heat is generated by combusting rice husks in the furnace. The heat generated through burning the fuel heats up water which is then used to produce steam. Steam produced from the water will turn a turbine and generator which produces electricity.
What is the rice husk fired steam boiler efficiency?
Rice husk boiler efficiency
Rice husk fired steam boiler efficiency is low. The rice husk-fired steam boiler heat transfer rate is small, and the temperature difference between different parts of the furnace wall is large, so it is easy to form a layer of thermal radiation film. So the overall thermal radiation loss is large and part of the heat transferred to cold air becomes hot air at low temperatures; The rice husk fired steam boiler water evaporation efficiency cannot be used effectively.
The moisture content in rice husk fuel will drop after burning and its calorific value drops as well. It can only achieve up to 50% combustion efficiency at best when using high-quality coal like metamorphic coke or anthracite coal which can reach up to 70%.
The above problems lead to low operating pressure and low steam quality, resulting in less steam produced per unit weight of fuel burned, thereby reducing power generation efficiency.
What is the running cost of rice husk fired steam boiler?
Rice husk boiler operation
The running cost of rice husk fired steam boiler is very low. It costs less than 1 cent per hour, which is equivalent to a few cents per day. The fuel cost is lower than 0.5 yuan/kilowatt-hour (US$0.04) and the maintenance cost is also very low, only about 0-0.2 yuan/kilowatt-hour (US$0.002 – US$0.008). The total running cost of a rice husk fired steam boiler can be calculated as follows:
Costs / hour = Power Consumption * Fuel Cost + Maintenance Cost*2
How much is the rice husk fired steam boiler?
Rice husk fired steam boiler cost
The price of a rice husk fired steam boiler depends on many factors, but generally, it’s between $400 and $750 per ton. The cost of installing and maintaining your rice husk fired steam boiler will depend on its size and what kind of fuel you’re using to run it. The average maintenance cost for a 500-kilowatt unit is $3,000 per year. Depending on the size and complexity of your system, operation costs may be higher or lower than this average figure. You can expect fuel costs from $5-8 per ton.
It is very simple to calculate the cost of a rice husk fired steam boiler. The price is calculated considering the capacity, type, model, and additional features. Rice husk fired steam boiler price depends on its size, efficiency, design, and other factors.
Rice husk-fired steam boiler cost is generally considered on a per unit basis or per KW basis depending upon the requirement of the customer and budget constraints by them.
The installation cost of a rice husk fired steam boiler varies with respect to the manufacturer who provides a complete package including piping work and other civil works along with their equipment at a given location.
