A composition for a Coating System (paint) which forms an insulating material being designed to both reflect infrared radiation and have reduced thermal conductivity. The coating system may be either a single Thermal Coating or may be a Thermal Coating used in combination with a Thermal Primer. The Thermal Coating is formulated using conventional techniques and a resin used in paint manufacture, but utilizes primary pigments and extender mineral pigments which preferentially reflect in the infra red area of the solar spectrum. A method of characterizing particulate materials for their infra red reflectivity is described, which provides a means for preferential selection of particulate additives based on their relative visible light and infrared reflectivity. Additionally the incorporation of hollow micro-spheres is desired to reduce thermal conductivity. The Thermal Primer is designed to provide adhesion between the Thermal Coating and the substrate on which it is applied and uses conventional techniques to achieve those properties. However it has been found advantageous to incorporate hollow micro-spheres with low thermal conductivity, such as glass, ceramic or polymeric micro-spheres and/or an extender pigment with low thermal conductivity such as calcined clay to further reduce heat flow through the Coating System.

An apparatus for collecting heat from a solar concentrator has an isothermal body defining an elongated cavity with a circular opening having a diameter equal to a diameter of a focus of the solar concentrator, the cavity having a reflective walls such that solar rays contacting the walls are substantially reflected. The circular opening is located at the focus of the solar concentrator and perpendicular to a principal axis of the solar concentrator, and the axis of the cavity is aligned with the principal axis of the solar concentrator. The heat generated in the isothermal body is absorbed by the heat sink. The length of the cavity is sufficient to absorb a desired proportion of the energy in the solar rays entering the cavity and is about 5 to 9 times the diameter of the opening of the cavity. Depending on material used, the isothermal body can be enclosed in a reducing atmosphere to maintain reflectivity of the cavity walls.

The invention relates to a new pole piece heating drying manner in a pole piece plating process of a lithium battery in a lithium ion power battery production process. According to the driving method and the driving device, electrode slurry plating on the pole pieces is finished through an induction heating coil on which intermediate-frequency AC power or high-frequency AC power is applied. The heating drying manner belongs to self-induction heating of a metal material. Heating of circulation air or heating to an overhigh temperature is not required, and therefore the drying device does not radiate a large amount of heat to an external environment, thereby realizing high heat efficiency. Furthermore energy consumption in a heating process and a cooling process for a large amount of circulation air is greatly reduced. Additionally, energy consumption in eliminating a solvent which is carried in the circulation air is reduced. The heating manner makes an overall thermal efficiency higher than 90%. Because a metal foil self-induction heating is adopted, the slurry which is plated on a substrate is dried from inside to outside, and micro channels which improve battery performance can be formed in the coated material.

The invention discloses a burning quality analysis and control system used for industrial stoves such as heating furnace, hot blast stove, boiler. Sampling pipe disposed at tail of the stove or in flue transfers sampled flue gas to purifying sampling chamber after the flue gas has been cooled, and oxygen sensor detects oxygen content value of the flue gas. As the oxygen content value of the flue gas in stove exceeds the predetermined value, i.e. excessive air distribution, the oxygen transmits the signal to a controller for comparing, operating or processing, and then transmits the processed signal to speed governor to reduce the rotation speed of blower group, i.e. air reduction, until air amount is appropriate; contrarily, if the oxygen content value of the flue gas in stove, detected by the oxygen sensor, is lower than the predetermined value, i.e. lacking air distribution, the speed governor will increase the rotation speed of the blower group, i.e. air increase, until air amount is appropriate, thereby, keeping the air consumption system of the stove in region of 1.0 to 1.1. The analysis and control system can not only improve burning quality of the industrial stove thereby providing economic benefit for user, but can also greatly reduce the emission of nitrogen oxides or carbon monoxide, therefore, has great popularization value.
