Generally, small gas-fired hot water boilers are between 0.7 MW and 14 MW, and the output of boilers is different, so the prices are different. Different pressures require different techniques, materials and pressures. The higher the pressure, the higher the price.
Because a certain amount of air is usually dissolved in water, with the increase of temperature, the solubility of air decreases, and the gas is gradually separates from the water in the process of water circulation, and gradually gathers together to form large bubbles and even gas columns. Gas is often produced due to the water supplement, so the boiler exhaust valve must be used to avoid damage to the system.
The ignition system of gas-fired boiler adopts high-energy igniter, which belongs to low-voltage capacitive discharge device. Its main structure is composed of nddh high-energy igniter, nddz igniter and nddl shielded ignition cable.
Ash accumulation on the heating surface.
The scaling and ash deposition on the water-cooled wall of the furnace and the ash deposition of the superheater, convention tube bundles, economizer and preheater can increase the thermal resistance of the flue gas, weaken the heat transfer, lessen the cooling effect of the flue gas and increase the exhaust gas temperature of the gas-fired boiler.
Too high excess air coefficient.
Under normal circumstances, as the furnace outlet excess...
Power boilers take the chemical energy stored in fuel, convert it to heat energy in the combustion process, and transfer that heat energy to water to produce steam. The transfer of energy from combustion gases to the water and steam is called heat transfer.
When it refers to how to reduce the procurement cost of industrial boilers, many corporate users will be first to take measures to effectively reduce the related costs involved in the boiler procurement process, such as the boiler equipment cost, transportation cost, loading and unloading cost, insurance cost, installation and commissioning cost, labor cost, acceptance and inspection cost.
In addition to quality, price is also an aspect that most corporate users are very concerned about when they purchase the gas-fired thermal oil heater, so what is the price of a set of high-quality gas-fired thermal oil heater?
1. The types and parameters of thermal oil heater, such as rated thermal power, rated working temperature, etc.
Rated thermal power: heat output per unit time. Thermal oil heaters with different heat output per unit time have different prices.
Rated wor...
Biogas is the mixture of gases produced by the breakdown of organic matter in the absence of oxygen (anaerobically), primarily consisting of methane and carbon dioxide. Biogas can be produced from raw materials such as agricultural waste, manure, municipal waste, plant material, sewage, green waste or food waste. Biogas is a renewable energy source.
Biogas is a byproduct of the decomposition of organic matter by anaerobic bacteria. Biogas is typically composed of 60% methane and 40% CO2...
